RESUMO
INTRODUCTION AND HYPOTHESIS: Our aim was to compare the mid-term results of native tissue, biological xenograft and polypropylene mesh surgery for women with vaginal wall prolapse. METHODS: A total of 1348 women undergoing primary transvaginal repair of an anterior and/or posterior prolapse were recruited between January 2010 and August 2013 from 35 UK centres. They were randomised by remote allocation to native tissue surgery, biological xenograft or polypropylene mesh. We performed both 4- and 6-year follow-up using validated patient-reported outcome measures. RESULTS: At 4 and 6 years post-operation, there was no clinically important difference in Pelvic Organ Prolapse Symptom Score for any of the treatments. Using a strict composite outcome to assess functional cure at 6 years, we found no difference in cure among the three types of surgery. Half the women were cured at 6 years but only 10.3 to 12% of women had undergone further surgery for prolapse. However, 8.4% of women in the mesh group had undergone further surgery for mesh complications. There was no difference in the incidence of chronic pain or dyspareunia between groups. CONCLUSIONS: At the mid-term outcome of 6 years, there is no benefit from augmenting primary prolapse repairs with polypropylene mesh inlays or biological xenografts. There was no evidence that polypropylene mesh inlays caused greater pain or dyspareunia than native tissue repairs.

BACKGROUND: Stress urinary incontinence constitutes a significant health and economic burden to society. Traditional suburethral slings are surgical operations used to treat women with symptoms of stress urinary incontinence. OBJECTIVES: To assess the effectiveness of traditional suburethral sling procedures for treating stress urinary incontinence in women; and summarise the principal findings of relevant economic evaluations. SEARCH METHODS: We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), as well as MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP); we handsearched journals and conference proceedings (searched 27 February 2017) and the reference lists of relevant articles. On 23 January 2019, we updated this search; as a result, several additional reports of studies are awaiting classification. SELECTION CRITERIA: Randomised or quasi-randomised trials that assessed traditional suburethral slings for treating stress or mixed urinary incontinence. DATA COLLECTION AND ANALYSIS: At least two review authors independently extracted data from included trials and assessed risk of bias. When appropriate, a summary statistic was calculated: risk ratio (RR) for dichotomous data, odds ratio (OR) for continence and cure rates that were expected to be high, and mean difference (MD) for continuous data. We adopted the GRADE approach to assess the quality of evidence. MAIN RESULTS: A total of 34 trials involving 3244 women were included. Traditional slings were compared with 10 other treatments and with each other. We did not identify any trials comparing suburethral slings with no treatment or sham treatment, conservative management, anterior repair, or laparoscopic retropubic colposuspension. Most trials did not distinguish between women having surgery for primary or recurrent incontinence. One trial compared traditional slings with bladder neck needle suspension, and another trial compared traditional slings with single-incision slings. Both trials were too small to be informative. Traditional suburethral sling operation versus drugs One small trial compared traditional suburethral sling operations with oxybutynin to treat women with mixed urinary incontinence. This trial did not report any of our GRADE-specific outcomes. It is uncertain whether surgery compared with oxybutynin leads to more women being dry (83% vs 0%; OR 195.89, 95% confidence interval (CI) 9.91 to 3871.03) or having less urgency urinary incontinence (13% vs 43%; RR 0.29, 95% CI 0.09 to 0.94) because the quality of this evidence is very low. Traditional suburethral sling versus injectables One small trial compared traditional slings with suburethral injectable treatment. The impact of surgery versus injectables is uncertain in terms of the number of continent women (100% were dry with a traditional sling versus 71% with the injectable after the first year; OR 11.57, 95% CI 0.56 to 239.74), the need for repeat surgery for urinary incontinence (RR 0.52, 95% CI 0.05 to 5.36) or the occurrence of perioperative complications (RR 1.57, 95% CI 0.29 to 8.49), as the quality of evidence is very low. Traditional suburethral sling versus open abdominal retropubic colposuspension Eight trials compared slings with open abdominal retropubic colposuspension. Moderate-quality evidence shows that the traditional suburethral sling probably leads to more continent women in the medium term (one to five years) (69% vs 59% after colposuspension: OR 1.70, 95% CI 1.22 to 2.37). High-quality evidence shows that women were less likely to need repeat continence surgery after a traditional sling operation than after colposuspension (RR 0.15, 95% CI 0.05 to 0.42). We found no evidence of a difference in perioperative complications between the two groups, but the CI was very wide and the quality of evidence was very low (RR 1.24, 95% CI 0.83 to 1.86). Traditional suburethral sling operation versus mid-urethral slings Fourteen trials compared traditional sling operations and mid-urethral sling operations. Depending on judgements about what constitutes a clinically important difference between interventions with regard to continence, traditional suburethral slings are probably no better, and may be less effective, than mid-urethral slings in terms of number of women continent in the medium term (one to five years) (67% vs 74%; OR 0.67, 95% CI 0.44 to 1.02; n = 458; moderate-quality evidence). One trial reported more continent women with the traditional sling after 10 years (51% vs 32%: OR 2.22, 95% CI 1.07 to 4.61). Mid-urethral slings may be associated with fewer perioperative complications (RR 1.74, 95% CI 1.16 to 2.60; low-quality evidence). One type of traditional sling operation versus another type of traditional sling operation Nine trials compared one type of traditional sling operation with another. The different types of traditional slings, along with the number of different materials used, mean that trial results could not be pooled due to clinical heterogeneity. Complications were reported by two trials - one comparing non-absorbable Goretex with a rectus fascia sling, and the second comparing Pelvicol with a rectus fascial sling. The impact was uncertain due to the very low quality of evidence. AUTHORS' CONCLUSIONS: Low-quality evidence suggests that women may be more likely to be continent in the medium term (one to five years) after a traditional suburethral sling operation than after colposuspension. It is very uncertain whether there is a difference in urinary incontinence after a traditional suburethral sling compared with a mid-urethral sling in the medium term. However, these findings should be interpreted with caution, as long-term follow-up data were not available from most trials. Long-term follow-up of randomised controlled trials (RCTs) comparing traditional slings with colposuspension and mid-urethral slings is essential. Evidence is insufficient to suggest whether traditional suburethral slings may be better or worse than other management techniques. This review is confined to RCTs and therefore may not identify all of the adverse effects that may be associated with these procedures. A brief economic commentary (BEC) identified three eligible economic evaluations, which are not directly comparable due to differences in methods, time horizons, and settings. End users of this review will need to assess the extent to which methods and results of identified economic evaluations may be applicable (or transferable) to their own setting.

BACKGROUND: Concerns have been raised about the safety of surgery for stress urinary incontinence and pelvic organ prolapse using transvaginal mesh. We assessed adverse outcomes after first, single mesh procedures and comparable non-mesh procedures. METHODS: We did a cohort study of women in Scotland aged 20 years or older undergoing a first, single incontinence procedure or prolapse procedure during 1997-98 to 2015-16 identified from a national hospital admission database. Primary outcomes were immediate postoperative complications and subsequent (within 5 years) readmissions for later postoperative complications, further incontinence surgery, or further prolapse surgery. Poisson regression models were used to compare outcomes after procedures carried out with and without mesh. FINDINGS: Between April 1, 1997, and March 31, 2016, 16â660 women underwent a first, single incontinence procedure, 13â133 (79%) of which used mesh. Compared with non-mesh open surgery (colposuspension), mesh procedures had a lower risk of immediate complications (adjusted relative risk [aRR] 0·44 [95% CI 0·36-0·55]) and subsequent prolapse surgery (adjusted incidence rate ratio [aIRR] 0·30 [0·24-0·39]), and a similar risk of further incontinence surgery (0·90 [0·73-1·11]) and later complications (1·12 [0·98-1·27]); all ratios are for retropubic mesh. During the same time period, 18â986 women underwent a first, single prolapse procedure, 1279 (7%) of which used mesh. Compared with non-mesh repair, mesh repair of anterior compartment prolapse was associated with a similar risk of immediate complications (aRR 0·93 [95% CI 0·49-1·79]); an increased risk of further incontinence (aIRR 3·20 [2·06-4·96]) and prolapse surgery (1·69 [1·29-2·20]); and a substantially increased risk of later complications (3·15 [2·46-4·04]). Compared with non-mesh repair, mesh repair of posterior compartment prolapse was associated with a similarly increased risk of repeat prolapse surgery and later complications. No difference in any outcome was observed between vaginal and, separately, abdominal mesh repair of vaginal vault prolapse compared with vaginal non-mesh repair. INTERPRETATION: Our results support the use of mesh procedures for incontinence, although further research on longer term outcomes would be beneficial. Mesh procedures for anterior and posterior compartment prolapse cannot be recommended for primary prolapse repair. Both vaginal and abdominal mesh procedures for vaginal vault prolapse repair are associated with similar effectiveness and complication rates to non-mesh vaginal repair. These results therefore do not clearly favour any particular vault repair procedure. FUNDING: None.

BACKGROUND: Pelvic floor muscle training can reduce prolapse severity and symptoms in women seeking treatment. We aimed to assess whether this intervention could also be effective in secondary prevention of prolapse and the need for future treatment. METHODS: We did this multicentre, parallel-group, randomised controlled trial at three centres in New Zealand and the UK. Women from a longitudinal study of pelvic floor function after childbirth were potentially eligible for inclusion. Women of any age who had stage 1-3 prolapse, but had not sought treatment, were randomly assigned (1:1), via remote computer allocation, to receive either one-to-one pelvic floor muscle training (five physiotherapy appointments over 16 weeks, and annual review) plus Pilates-based pelvic floor muscle training classes and a DVD for home use (intervention group), or a prolapse lifestyle advice leaflet (control group). Randomisation was minimised by centre, parity (three or less vs more than three deliveries), prolapse stage (above the hymen vs at or beyond the hymen), and delivery method (any vaginal vs all caesarean sections). Women and intervention physiotherapists could not be masked to group allocation, but allocation was masked from data entry researchers and from the trial statistician until after database lock. The primary outcome was self-reported prolapse symptoms (Pelvic Organ Prolapse Symptom Score [POP-SS]) at 2 years. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01171846. FINDINGS: Between Dec 21, 2008, and Feb 24, 2010, in New Zealand, and Oct 27, 2010, and Sept 5, 2011, in the UK, we randomly assigned 414 women to the intervention group (n=207) or the control group (n=207). One participant in each group was excluded after randomisation, leaving 412 women for analysis. At baseline, 399 (97%) women had prolapse above or at the level of the hymen. The mean POP-SS score at 2 years was 3·2 (SD 3·4) in the intervention group versus 4·2 (SD 4·4) in the control group (adjusted mean difference -1·01, 95% CI -1·70 to -0·33; p=0·004). The mean symptom score stayed similar across time points in the control group, but decreased in the intervention group. Three adverse events were reported, all of which were in the intervention group (one women had a fall, one woman had a pain in her tail bone, and one woman had chest pain and shortness of breath). INTERPRETATION: Our study shows that pelvic floor muscle training leads to a small, but probably important, reduction in prolapse symptoms. This finding will be important for women and caregivers considering preventive strategies.

BACKGROUND: The use of transvaginal mesh and biological graft material in prolapse surgery is controversial and has led to a number of enquiries into their safety and efficacy. Existing trials of these augmentations are individually too small to be conclusive. We aimed to compare the outcomes of prolapse repair involving either synthetic mesh inlays or biological grafts against standard repair in women. METHODS: We did two pragmatic, parallel-group, multicentre, randomised controlled trials for our study (PROSPECT [PROlapse Surgery: Pragmatic Evaluation and randomised Controlled Trials]) in 35 centres (a mix of secondary and tertiary referral hospitals) in the UK. We recruited women undergoing primary transvaginal anterior or posterior compartment prolapse surgery by 65 gynaecological surgeons in these centres. We randomly assigned participants by a remote web-based randomisation system to one of the two trials: comparing standard (native tissue) repair alone with standard repair augmented with either synthetic mesh (the mesh trial) or biological graft (the graft trial). We assigned women (1:1:1 or 1:1) within three strata: assigned to one of the three treatment options, comparison of standard repair with mesh, and comparison of standard repair with graft. Participants, ward staff, and outcome assessors were masked to randomisation where possible; masking was obviously not possible for the surgeon. Follow-up was for 2 years after the surgery; the primary outcomes, measured at 1 year and 2 years, were participant-reported prolapse symptoms (i.e. the Pelvic Organ Prolapse Symptom Score [POP-SS]) and condition-specific (ie, prolapse-related) quality-of-life scores, analysed in the modified intention-to-treat population. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN60695184. FINDINGS: Between Jan 8, 2010, and Aug 30, 2013, we randomly allocated 1352 women to treatment, of whom 1348 were included in the analysis. 865 women were included in the mesh trial (430 to standard repair alone, 435 to mesh augmentation) and 735 were included in the graft trial (367 to standard repair alone, 368 to graft augmentation). Because the analyses were carried out separately for each trial (mesh trial and graft trial) some women in the standard repair arm assigned to all treatment options were included in the standard repair group of both trials. 23 of these women did not receive any surgery (15 in the mesh trial, 13 in the graft trial; five were included in both trials) and were included in the baseline analyses only. Mean POP-SS at 1 year did not differ substantially between comparisons (standard 5·4 [SD 5·5] vs mesh 5·5 [5·1], mean difference 0·00, 95% CI -0·70 to 0·71; p=0·99; standard 5·5 [SD 5·6] vs graft 5·6 [5·6]; mean difference -0·15, -0·93 to 0·63; p=0·71). Mean prolapse-related quality-of-life scores also did not differ between groups at 1 year (standard 2·0 [SD 2·7] vs mesh 2·2 [2·7], mean difference 0·13, 95% CI -0·25 to 0·51; p=0·50; standard 2·2 [SD 2·8] vs graft 2·4 [2·9]; mean difference 0·13, -0·30 to 0·56; p=0·54). Mean POP-SS at 2 years were: standard 4·9 (SD 5·1) versus mesh 5·3 (5·1), mean difference 0·32, 95% CI -0·39 to 1·03; p=0·37; standard 4·9 (SD 5·1) versus graft 5·5 (5·7); mean difference 0·32, -0·48 to 1·12; p=0·43. Prolapse-related quality-of-life scores at 2 years were: standard 1·9 (SD 2·5) versus mesh 2·2 (2·6), mean difference 0·15, 95% CI -0·23 to 0·54; p=0·44; standard 2·0 (2·5) versus graft 2·2 (2·8); mean difference 0·10, -0·33 to 0·52; p=0·66. Serious adverse events such as infection, urinary retention, or dyspareunia or other pain, excluding mesh complications, occurred with similar frequency in the groups over 1 year (mesh trial: 31/430 [7%] with standard repair vs 34/435 [8%] with mesh, risk ratio [RR] 1·08, 95% CI 0·68 to 1·72; p=0·73; graft trial: 23/367 [6%] with standard repair vs 36/368 [10%] with graft, RR 1·57, 0·95 to 2·59; p=0·08). The cumulative number of women with a mesh complication over 2 years in women actually exposed to synthetic mesh was 51 (12%) of 434. INTERPRETATION: Augmentation of a vaginal repair with mesh or graft material did not improve women's outcomes in terms of effectiveness, quality of life, adverse effects, or any other outcome in the short term, but more than one in ten women had a mesh complication. Therefore, follow-up is vital to identify any longer-term potential benefits and serious adverse effects of mesh or graft reinforcement in vaginal prolapse surgery.

BACKGROUND: Bladder neck needle suspension is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience some urinary incontinence, and about a third of these have moderate or severe symptoms. Stress urinary incontinence (SUI) imposes significant health and economic burdens on society and the women affected. OBJECTIVES: To determine the effects of needle suspension on stress or mixed urinary incontinence in comparison with other management options. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 12 November 2014), and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised trials that included needle suspension for the treatment of urinary incontinence. DATA COLLECTION AND ANALYSIS: At least two authors assessed trials and extracted data independently. Two trial investigators provided additional information. MAIN RESULTS: We identified 10 trials, which included 375 women having six different types of needle suspension procedures and 489 who received comparison interventions. Needle suspensions were more likely to fail than open abdominal retropubic suspension. There was a higher subjective failure rate after the first year (91/313 (29%) failed versus 47/297 (16%) failed after open abdominal retropubic suspension). The risk ratio (RR) was 2.00 (95% confidence interval (CI) 1.47 to 2.72), although the difference in peri-operative complications was not significant (17/75 (23%) versus 12/77 (16%); RR 1.44, 95% CI 0.73 to 2.83). There were no significant differences for the other outcome measures. This effect was seen in both women with primary incontinence and women with recurrent incontinence after failed primary operations. Needle suspensions may be as effective as anterior vaginal repair (50/156 (32%) failed after needle suspension versus 64/181 (35%) after anterior repair; RR 0.86, 95% CI 0.64 to 1.16), but there was little information about morbidity. Data for comparison with suburethral slings were inconclusive because they came from a small and atypical population.No trials compared needle suspensions with conservative management, peri-urethral injections, or sham or laparoscopic surgery. AUTHORS' CONCLUSIONS: Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary and secondary urodynamic stress incontinence because the cure rates were lower in the trials reviewed. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity. A Brief Economic Commentary (BEC) identified no cost-effectiveness studies comparing bladder neck needle suspension with other surgeries.

BACKGROUND: Anterior vaginal repair (anterior colporrhaphy) is an operation traditionally used for moderate or severe stress urinary incontinence (SUI) in women. About a third of adult women experience urinary incontinence. SUI imposes significant health and economic burden to the society and the women affected. OBJECTIVES: To determine the effects of anterior vaginal repair (anterior colporrhaphy) on urinary incontinence in comparison with other management options. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Trials Register (searched 1 September 2009) and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised trials that included anterior vaginal repair for the treatment of urinary incontinence. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed trial quality. Three trial investigators were contacted for additional information. MAIN RESULTS: Ten trials were identified which included 385 women having an anterior vaginal repair and 627 who received comparison interventions.A single small trial provided insufficient evidence to assess anterior vaginal repair in comparison with physical therapy. The performance of anterior repair in comparison with bladder neck needle suspension appeared similar (risk ratio (RR) for failure after one year 1.16, 95% confidence interval (CI) 0.86 to 1.56), but clinically important differences could not be confidently ruled out. No trials compared anterior repair with suburethral sling operations or laparoscopic colposuspensions, or compared alternative vaginal operations.Anterior vaginal repair was less effective than open abdominal retropubic suspension based on patient-reported cure rates in eight trials both in the medium term (failure rate within one to five years after anterior repair 97/259 (38%) versus 57/327 (17%); RR 2.29, 95% confidence Interval (CI) 1.70 to 3.08) and in the long term (after five years, (49/128 (38%) versus 31/145 (21%); RR 2.02, 95% CI 1.36 to 3.01). There was evidence from three of these trials that this was reflected in a need for more repeat operations for incontinence (25/107 (23%) versus 4/164 (2%); RR 8.87, 95% CI 3.28 to 23.94). These findings held, irrespective of the co-existence of prolapse (pelvic relaxation). Although fewer women had a prolapse after anterior repair (RR 0.24, 95% CI 0.12 to 0.47), later prolapse operation appeared to be equally common after vaginal (3%) or abdominal (4%) operation.In respect of the type of open abdominal retropubic suspension, most data related to comparisons of anterior vaginal repair with Burch colposuspension. The few data describing comparison of anterior repair with the Marshall-Marchetti-Krantz procedure were consistent with those for Burch colposuspension. AUTHORS' CONCLUSIONS: There were not enough data to allow comparison of anterior vaginal repair with physical therapy or needle suspension for primary urinary stress incontinence in women. Open abdominal retropubic suspension appeared to be better than anterior vaginal repair judged on subjective cure rates in eight trials, even in women who had prolapse in addition to stress incontinence (six trials). The need for repeat incontinence surgery was also less after the abdominal operation. However, there was not enough information about postoperative complications and morbidity.A Brief Economic Commentary (BEC) identified one study suggesting that vaginoplasty may be more cost-effective compared with tension-free vaginal tape (TVT-O).

BACKGROUND: Several treatment options are available for stress urinary incontinence (SUI), including pelvic floor muscle training (PFMT), drug therapy and surgery. Problems exist such as adherence to PFMT regimens, side effects linked to drug therapy and the risks associated with surgery. We have evaluated an alternative treatment, electrical stimulation (ES) with non-implanted devices, which aims to improve pelvic floor muscle function to reduce involuntary urine loss. OBJECTIVES: To assess the effects of electrical stimulation with non-implanted devices, alone or in combination with other treatment, for managing stress urinary incontinence or stress-predominant mixed urinary incontinence in women. Among the outcomes examined were costs and cost-effectiveness. SEARCH METHODS: We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP and handsearches of journals and conference proceedings (searched 27 February 2017). We also searched the reference lists of relevant articles and undertook separate searches to identify studies examining economic data. SELECTION CRITERIA: We included randomised or quasi-randomised controlled trials of ES with non-implanted devices compared with any other treatment for SUI in women. Eligible trials included adult women with SUI or stress-predominant mixed urinary incontinence (MUI). We excluded studies of women with urgency-predominant MUI, urgency urinary incontinence only, or incontinence associated with a neurologic condition. We would have included economic evaluations had they been conducted alongside eligible trials. DATA COLLECTION AND ANALYSIS: Two review authors independently screened search results, extracted data from eligible trials and assessed risk of bias, using the Cochrane 'Risk of bias' tool. We would have performed economic evaluations using the approach recommended by Cochrane Economic Methods. MAIN RESULTS: We identified 56 eligible trials (3781 randomised participants). Eighteen trials did not report the primary outcomes of subjective cure, improvement of SUI or incontinence-specific quality of life (QoL). The risk of bias was generally unclear, as most trials provided little detail when reporting their methods. We assessed 25% of the included trials as being at high risk of bias for a variety of reasons, including industry funding and baseline differences between groups. We did not identify any economic evaluations.For subjective cure of SUI, we found moderate-quality evidence that ES is probably better than no active treatment (risk ratio (RR) 2.31, 95% CI 1.06 to 5.02). We found a similar result for cure or improvement of SUI (RR 1.73, 95% CI 1.41 to 2.11), but the quality of evidence was lower. We are very uncertain if there is a difference between ES and sham treatment in terms of subjective cure because of the very low quality of evidence (RR 2.21, 95% CI 0.38 to 12.73). For subjective cure or improvement, ES may be better than sham treatment (RR 2.03, 95% CI 1.02 to 4.07). The effect estimate was 660/1000 women cured/improved with ES compared to 382/1000 with no active treatment (95% CI 538 to 805 women); and for sham treatment, 402/1000 women cured/improved with ES compared to 198/1000 with sham treatment (95% CI 202 to 805 women).Low-quality evidence suggests that there may be no difference in cure or improvement for ES versus PFMT (RR 0.85, 95% CI 0.70 to 1.03), PFMT plus ES versus PFMT alone (RR 1.10, 95% CI 0.95 to 1.28) or ES versus vaginal cones (RR 1.09, 95% CI 0.97 to 1.21).Electrical stimulation probably improves incontinence-specific QoL compared to no treatment (moderate quality evidence) but there may be little or no difference between electrical stimulation and PFMT (low quality evidence). It is uncertain whether adding electrical stimulation to PFMT makes any difference in terms of quality of life, compared with PFMT alone (very low quality evidence). There may be little or no difference between electrical stimulation and vaginal cones in improving incontinence-specific QoL (low quality evidence). The impact of electrical stimulation on subjective cure/improvement and incontinence-specific QoL, compared with vaginal cones, PFMT plus vaginal cones, or drugs therapy, is uncertain (very low quality evidence).In terms of subjective cure/improvement and incontinence-specific QoL, the available evidence comparing ES versus drug therapy or PFMT plus vaginal cones was very low quality and inconclusive. Similarly, comparisons of different types of ES to each other and of ES plus surgery to surgery are also inconclusive in terms of subjective cure/improvement and incontinence-specific QoL (very low-quality evidence).Adverse effects were rare: in total nine of the women treated with ES in the trials reported an adverse effect. We identified insufficient evidence to compare the risk of adverse effects in women treated with ES compared to any other treatment. We were unable to identify any economic data. AUTHORS' CONCLUSIONS: The current evidence base indicated that electrical stimulation is probably more effective than no active or sham treatment, but it is not possible to say whether ES is similar to PFMT or other active treatments in effectiveness or not. Overall, the quality of the evidence was too low to provide reliable results. Without sufficiently powered trials measuring clinically important outcomes, such as subjective assessment of urinary incontinence, we cannot draw robust conclusions about the overall effectiveness or cost-effectiveness of electrical stimulation for stress urinary incontinence in women.

BACKGROUND: Pelvic organ prolapse is common and is strongly associated with childbirth and increasing age. Women with prolapse are often advised to do pelvic floor muscle exercises, but evidence supporting the benefits of such exercises is scarce. We aimed to establish the effectiveness of one-to-one individualised pelvic floor muscle training for reducing prolapse symptoms. METHODS: We did a parallel-group, multicentre, randomised controlled trial at 23 centres in the UK, one in New Zealand, and one in Australia, between June 22, 2007, and April 9, 2010. Female outpatients with newly-diagnosed, symptomatic stage I, II, or III prolapse were randomly assigned (1:1), by remote computer allocation with minimsation, to receive an individualised programme of pelvic floor muscle training or a prolapse lifestyle advice leaflet and no muscle training (control group). Outcome assessors, and investigators who were gynaecologists at trial sites, were masked to group allocation; the statistician was masked until after data analysis. Our primary endpoint was participants' self-report of prolapse symptoms at 12 months. Analysis was by intention-to-treat analysis. This trial is registered, number ISRCTN35911035. FINDINGS: 447 eligible patients were randomised to the intervention group (n=225) or the control group (n=222). 377 (84%) participants completed follow-up for questionnaires at 6 months and 295 (66%) for questionnaires at 12 months. Women in the intervention group reported fewer prolapse symptoms (ie, a significantly greater reduction in the pelvic organ prolapse symptom score [POP-SS]) at 12 months than those in the control group (mean reduction in POP-SS from baseline 3.77 [SD 5.62] vs 2.09 [5.39]; adjusted difference 1.52, 95% CI 0.46-2.59; p=0.0053). Findings were robust to missing data. Eight adverse events (six vaginal symptoms, one case of back pain, and one case of abdominal pain) and one unexpected serious adverse event, all in women from the intervention group, were regarded as unrelated to the intervention or to participation in the study. INTERPRETATION: One-to-one pelvic floor muscle training for prolapse is effective for improvement of prolapse symptoms. Long-term benefits should be investigated, as should the effects in specific subgroups.

BACKGROUND: Urodynamic tests are used to investigate people who have urinary incontinence or other urinary symptoms in order to make an objective diagnosis. The investigations are invasive and time consuming. OBJECTIVES: To determine if treatment according to a urodynamic-based diagnosis, compared to treatment based on history and examination, leads to more effective clinical care and better clinical outcomes. SEARCH METHODS: Cochrane Incontinence Group Specialized Register (searched February 19, 2013); reference lists of relevant articles. SELECTION CRITERIA: Randomized and quasi-randomized trials in people who were and were not investigated using urodynamics, or comparing one type of urodynamic test against another. DATA COLLECTION AND ANALYSIS: At least two independent review authors carried out trial assessment, selection, and data abstraction. RESULTS: We found eight trials but data were available for only 1,036 women in seven trials. Women undergoing urodynamics were more likely to have their management changed (17% vs. 3%, risk ratio [RR] 5.07, 95% CI 1.87-13.74). Two trials suggested that women were more likely to receive drugs (RR 2.09, 95% CI 1.32-3.31), but, in five trials, women were not more likely to undergo surgery (RR 0.99, 95% CI 0.88-1.12). There was no statistically significant difference in urinary incontinence in women who had urodynamics (37%) compared with those undergoing history and clinical examination alone (36%) (RR 1.02, 95% CI 0.86-1.21). AUTHORS' CONCLUSIONS: While urodynamics did change clinical decision-making, there was some high-quality evidence that this did not result in lower urinary incontinence rates after treatment.

BACKGROUND: Urinary incontinence is common after radical prostatectomy and can also occur in some circumstances after transurethral resection of the prostate (TURP). Conservative management includes pelvic floor muscle training with or without biofeedback, electrical stimulation, extra-corporeal magnetic innervation (ExMI), compression devices (penile clamps), lifestyle changes, or a combination of methods. OBJECTIVES: To determine the effectiveness of conservative management for urinary incontinence up to 12 months after transurethral, suprapubic, laparoscopic, radical retropubic or perineal prostatectomy, including any single conservative therapy or any combination of conservative therapies. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register (5 February 2014), CENTRAL (2014, Issue 1), EMBASE (January 2010 to Week 3 2014), CINAHL (January 1982 to 18 January 2014), ClinicalTrials.gov and World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (both searched 29 January 2014), and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials evaluating conservative interventions for urinary continence in men after prostatectomy. DATA COLLECTION AND ANALYSIS: Two or more review authors assessed the methodological quality of the trials and abstracted data. We tried to contact several authors of included studies to obtain extra information. MAIN RESULTS: Fifty trials met the inclusion criteria, 45 in men after radical prostatectomy, four trials after TURP and one trial after either operation. The trials included 4717 men of whom 2736 had an active conservative intervention. There was considerable variation in the interventions, populations and outcome measures. Data were not available for many of the pre-stated outcomes. Men's symptoms improved over time irrespective of management.There was no evidence from eight trials that pelvic floor muscle training with or without biofeedback was better than control for men who had urinary incontinence up to 12 months after radical prostatectomy; the quality of the evidence was judged to be moderate (for example 57% with urinary incontinence in the intervention group versus 62% in the control group, risk ratio (RR) for incontinence after 12 months 0.85, 95% confidence interval (CI) 0.60 to 1.22). One large multi-centre trial of one-to-one therapy showed no difference in any urinary or quality of life outcome measures and had narrow CIs. It seems unlikely that men benefit from one-to-one PFMT therapy after TURP. Individual small trials provided data to suggest that electrical stimulation, external magnetic innervation, or combinations of treatments might be beneficial but the evidence was limited. Amongst trials of conservative treatment for all men after radical prostatectomy, aimed at both treatment and prevention, there was moderate evidence of an overall benefit from pelvic floor muscle training versus control management in terms of reduction of urinary incontinence (for example 10% with urinary incontinence after one year in the intervention groups versus 32% in the control groups, RR for urinary incontinence 0.32, 95% CI 0.20 to 0.51). However, this finding was not supported by other data from pad tests. The findings should be treated with caution because the risk of bias assessment showed methodological limitations. Men in one trial were more satisfied with one type of external compression device, which had the lowest urine loss, compared to two others or no treatment. The effect of other conservative interventions such as lifestyle changes remained undetermined as no trials involving these interventions were identified. AUTHORS' CONCLUSIONS: The value of the various approaches to conservative management of postprostatectomy incontinence after radical prostatectomy remains uncertain. The evidence is conflicting and therefore rigorous, adequately powered randomised controlled trials (RCTs) which abide by the principles and recommendations of the CONSORT statement are still needed to obtain a definitive answer. The trials should be robustly designed to answer specific well constructed research questions and include outcomes which are important from the patient's perspective in decision making and are also relevant to the healthcare professionals. Long-term incontinence may be managed by an external penile clamp, but there are safety problems.

BACKGROUND: Bladder neck needle suspension is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience some urinary incontinence, and about a third of these have moderate or severe symptoms. OBJECTIVES: To determine the effects of needle suspension on stress or mixed urinary incontinence in comparison with other management options. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 12 November 2014), and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised trials that included needle suspension for the treatment of urinary incontinence. DATA COLLECTION AND ANALYSIS: At least two authors assessed trials and extracted data independently. Two trial investigators provided additional information. MAIN RESULTS: We identified 10 trials, which included 375 women having six different types of needle suspension procedures and 489 who received comparison interventions. Needle suspensions were more likely to fail than open abdominal retropubic suspension. There was a higher subjective failure rate after the first year (91/313 (29%) failed versus 47/297 (16%) failed after open abdominal retropubic suspension). The risk ratio (RR) was 2.00 (95% confidence interval (CI) 1.47 to 2.72), although the difference in peri-operative complications was not significant (17/75 (23%) versus 12/77 (16%); RR 1.44, 95% CI 0.73 to 2.83). There were no significant differences for the other outcome measures. This effect was seen in both women with primary incontinence and women with recurrent incontinence after failed primary operations. Needle suspensions may be as effective as anterior vaginal repair (50/156 (32%) failed after needle suspension versus 64/181 (35%) after anterior repair; RR 0.86, 95% CI 0.64 to 1.16), but there was little information about morbidity. Data for comparison with suburethral slings were inconclusive because they came from a small and atypical population.No trials compared needle suspensions with conservative management, peri-urethral injections, or sham or laparoscopic surgery. AUTHORS' CONCLUSIONS: Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary and secondary urodynamic stress incontinence because the cure rates were lower in the trials reviewed. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity.

BACKGROUND: Catheter-associated urinary tract infection (CAUTI) is a major preventable cause of harm for patients in hospital. We aimed to establish whether short-term routine use of antimicrobial catheters reduced risk of CAUTI compared with standard polytetrafluoroethylene (PTFE) catheterisation. METHODS: In our parallel, three group, multicentre, randomised controlled superiority trial, we enrolled adults (aged ≥16 years) requiring short-term (≤14 days) catheterisation at 24 hospitals in the UK. Participants were randomly allocated 1:1:1 with a remote computer allocation to receive a silver alloy-coated catheter, a nitrofural-impregnated catheter, or a PTFE-coated catheter (control group). Patients undergoing unplanned catheterisation were also included and consent for participation was obtained retrospectively. Participants and trial staff were unmasked to treatment assignment. Data were collected by trial staff and by patient-reported questionnaires for 6 weeks after randomisation. The primary outcome was incidence of symptomatic urinary tract infection for which an antibiotic was prescribed by 6 weeks. We postulated that a 3·3% absolute reduction in CAUTI would represent sufficient benefit to recommend routine use of antimicrobial catheters. This study is registered, number ISRCTN75198618. FINDINGS: 708 (10%) of 7102 randomly allocated participants were not catheterised, did not confirm consent, or withdrew, and were not included in the primary analyses. Compared with 271 (12·6%) of 2144 participants in the control group, 263 (12·5%) of 2097 participants allocated a silver alloy catheter had the primary outcome (difference -0·1% [95% CI -2·4 to 2·2]), as did 228 (10·6%) of 2153 participants allocated a nitrofural catheter (-2·1% [-4·2 to 0·1]). Rates of catheter-related discomfort were higher in the nitrofural group than they were in the other groups. INTERPRETATION: Silver alloy-coated catheters were not effective for reduction of incidence of symptomatic CAUTI. The reduction we noted in CAUTI associated with nitrofural-impregnated catheters was less than that regarded as clinically important. Routine use of antimicrobial-impregnated catheters is not supported by this trial. FUNDING: UK National Institute for Health Research Health Technology Assessment Programme.

BACKGROUND: Urodynamic tests are used to investigate people who have urinary incontinence or other urinary symptoms in order to make a definitive, objective diagnosis. The aim is to help select the treatment most likely to be successful. The investigations are invasive and time consuming. OBJECTIVES: The objective of this review was to determine if treatment according to a urodynamic-based diagnosis, compared to treatment based on history and examination, led to more effective clinical care of people with urinary incontinence and better clinical outcomes.The intention was to test the following hypotheses in predefined subgroups of people with incontinence:(i) urodynamic investigations improve the clinical outcomes;(ii) urodynamic investigations alter clinical decision making;(iii) one type of urodynamic test is better than another in improving the outcomes of management of incontinence or influencing clinical decisions, or both. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE In-Process, handsearching of journals and conference proceedings (searched 19 February 2013), and the reference lists of relevant articles. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing clinical outcomes in groups of people who were and were not investigated using urodynamics, or comparing one type of urodynamic test against another were included. Trials were excluded if they did not report clinical outcomes. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. MAIN RESULTS: Eight trials involving around 1100 people were included but data were only available for 1036 women in seven trials, of whom 526 received urodynamics. There was some evidence of risk of bias. The four deaths and 12 dropouts in the control arm of one trial were unexplained.There was significant evidence that the tests did change clinical decision making. Women in the urodynamic arms of three trials were more likely to have their management changed (proportion with change in management compared with the control arm 17% versus 3%, risk ratio (RR) 5.07, 95% CI 1.87 to 13.74), although there was statistical heterogeneity. There was evidence from two trials that women treated after urodynamic investigations were more likely to receive drugs (RR 2.09, 95% CI 1.32 to 3.31). On the other hand, in five trials women undergoing treatment following urodynamic investigation were not more likely to undergo surgery (RR 0.99, 95% CI 0.88 to 1.12).There was no statistically significant difference however in the number of women with urinary incontinence if they received treatment guided by urodynamics (37%) compared with those whose treatment was based on history and clinical findings alone (36%) (for example, RR for the number with incontinence after the first year 1.02, 95% CI 0.86 to 1.21). It was calculated that the number of women needed to treat was 100 women (95% CI 86 to 114 women) undergoing urodynamics to prevent one extra individual being incontinent at one year.One trial reported adverse effects and no significant difference was found (RR 1.10, 95% CI 0.81 to 1.50). AUTHORS' CONCLUSIONS: While urodynamic tests did change clinical decision making, there was some evidence that this did not result in better outcomes in terms of a difference in urinary incontinence rates after treatment. There was no evidence about their use in men, children, or people with neurological diseases. Larger definitive trials are needed in which people are randomly allocated to management according to urodynamic findings or to management based on history and clinical examination to determine if performance of urodynamics results in higher continence rates after treatment.

BACKGROUND: Urinary incontinence is common immediately after prostate surgery. Men are often advised to do pelvic-floor exercises, but evidence to support this is inconclusive. Our aim was to establish if formal one-to-one pelvic floor muscle training reduces incontinence. METHODS: We undertook two randomised trials in men in the UK who were incontinent 6 weeks after radical prostatectomy (trial 1) or transurethral resection of the prostate (TURP; trial 2) to compare four sessions with a therapist over 3 months with standard care and lifestyle advice only. Randomisation was by remote computer allocation. Our primary endpoints, collected via postal questionnaires, were participants' reports of urinary incontinence and incremental cost per quality-adjusted life year (QALY) after 12 months. Group assignment was masked from outcome assessors, but this masking was not possible for participants or caregivers. We used intention-to-treat analyses to compare the primary outcome at 12 months. This study is registered, number ISRCTN87696430. FINDINGS: In the intervention group in trial 1, the rate of urinary incontinence at 12 months (148 [76%] of 196) was not significantly different from the control group (151 [77%] of 195; absolute risk difference [RD] -1·9%, 95% CI -10 to 6). In trial 2, the difference in the rate of urinary incontinence at 12 months (126 [65%] of 194) from the control group was not significant (125 [62%] of 203; RD 3·4%, 95% CI -6 to 13). Adjusting for minimisation factors or doing treatment-received analyses did not change these results in either trial. No adverse effects were reported. In both trials, the intervention resulted in higher mean costs per patient (£180 and £209 respectively) but we did not identify evidence of an economically important difference in QALYs (0·002 [95% CI -0·027 to 0·023] and -0·00003 [-0·026 to 0·026]). INTERPRETATION: In settings where information about pelvic-floor exercise is widely available, one-to-one conservative physical therapy for men who are incontinent after prostate surgery is unlikely to be effective or cost effective. The high rates of persisting incontinence after 12 months suggest a substantial unrecognised and unmet need for management in these men.

Women in the urodynamic arms of two trials were more likely to have their management changed but this did not quite reach statistical significance (proportion with no change in management 76% versus 99%, RR 0.79, 95% CI 0.57 to 1.10).However, there was not enough evidence to demonstrate whether or not this resulted in a clinical benefit. For example there was no statistically significant difference in the number of women with urinary incontinence if they received treatment guided by urodynamics (70%) versus those whose treatment was based on history and clinical findings alone (62%) (e.g. RR for number with incontinence after first year 1.23, 95% CI 0.60 to 2.55).No trials reported whether or not there were any adverse effects. AUTHORS' CONCLUSIONS: While urodynamic tests may change clinical decision making, there was not enough evidence to suggest whether this would result in better clinical outcomes. There was no evidence abut their use in men, children or people with neurological diseases. Larger definitive trials are needed, in which people are randomly allocated to management according to urodynamic findings or to standard management based on history and clinical examination.

BACKGROUND: Urinary incontinence is common after both radical prostatectomy and transurethral resection of the prostate (TURP). Conservative management includes pelvic floor muscle training with or without biofeedback, electrical stimulation, extra-corporeal magnetic innervation (ExMI), compression devices (penile clamps), lifestyle changes, or a combination of methods. OBJECTIVES: To assess the effects of conservative management for urinary incontinence after prostatectomy. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register (searched 24 August 2011), EMBASE (January 1980 to Week 48 2009), CINAHL (January 1982 to 20 November 2009), the reference lists of relevant articles, handsearched conference proceedings and contacted investigators to locate studies. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials evaluating conservative interventions for urinary continence in men after prostatectomy. DATA COLLECTION AND ANALYSIS: Two or more review authors assessed the methodological quality of trials and abstracted data. We tried to contact several authors of included studies to obtain extra information. MAIN RESULTS: Thirty-seven trials met the inclusion criteria, 33 amongst men after radical prostatectomy, three trials after transurethral resection of the prostate (TURP) and one trial after either operation. The trials included 3399 men, of whom 1937 had an active conservative intervention. There was considerable variation in the interventions, populations and outcome measures. Data were not available for many of the pre-stated outcomes. Men's symptoms improved over time irrespective of management. Adverse effects did not occur or were not reported.There was no evidence from eight trials that pelvic floor muscle training with or without biofeedback was better than control for men who had urinary incontinence after radical prostatectomy (e.g. 57% with urinary incontinence versus 62% in the control group, risk ratio (RR) for incontinence after 12 months 0.85, 95% confidence interval (CI) 0.60 to 1.22) as the confidence intervals were wide, reflecting uncertainty. However, one large multicentre trial of one-to-one therapy showed no difference in any urinary or quality of life outcome measures and had narrower confidence intervals. There was also no evidence of benefit for erectile dysfunction (56% with no erection in the pelvic floor muscle training group versus 55% in the control group after one year, RR 1.01, 95% CI 0.84 to 1.20). Individual small trials provided data to suggest that electrical stimulation, external magnetic innervation or combinations of treatments might be beneficial but the evidence was limited. One large trial demonstrated that there was no benefit for incontinence or erectile dysfunction from a one-to-one pelvic floor muscle training based intervention to men who were incontinent after transurethral resection of the prostate (TURP) (e.g. 65% with urinary incontinence versus 62% in the control group, RR after 12 months 1.05, 95% CI 0.91 to 1.23).In eight trials of conservative treatment of all men after radical prostatectomy aimed at both treatment and prevention, there was an overall benefit from pelvic floor muscle training versus control management in terms of reduction of UI (e.g. 10% with urinary incontinence after one year versus 32% in the control groups, RR for urinary incontinence 0.32, 95% CI 0.20 to 0.51). However, this finding was not supported by other data from pad tests. The findings should be treated with caution, as most trials were of poor to moderate quality and confidence intervals were wide. Men in one trial were more satisfied with one type of external compression device, which had the lowest urine loss, compared to two others or no treatment. The effect of other conservative interventions such as lifestyle changes remains undetermined as no trials involving these interventions were identified. AUTHORS' CONCLUSIONS: The value of the various approaches to conservative management of postprostatectomy incontinence after radical prostatectomy remains uncertain. It seems unlikely that men benefit from one-to-one pelvic floor muscle training therapy after transurethral resection of the prostate (TURP). Long-term incontinence may be managed by external penile clamp, but there are safety problems.

BACKGROUND: Stress urinary incontinence is common in men after prostate surgery and can be difficult to improve. Implantation of an artificial urinary sphincter is the most common surgical procedure for persistent stress urinary incontinence, but it requires specialist surgical skills, and revisions may be necessary. In addition, the sphincter is relatively expensive and its operation requires adequate patient dexterity. New surgical approaches include the male synthetic sling, which is emerging as a possible alternative. However, robust comparable data, derived from randomised controlled trials, on the relative safety and efficacy of the male synthetic sling and the artificial urinary sphincter are lacking. OBJECTIVE: We aimed to compare the clinical effectiveness and cost-effectiveness of the male synthetic sling with those of the artificial urinary sphincter surgery in men with persistent stress urinary incontinence after prostate surgery. DESIGN: This was a multicentre, non-inferiority randomised controlled trial, with a parallel non-randomised cohort and embedded qualitative component. Randomised controlled trial allocation was carried out by remote web-based randomisation (1 : 1), minimised on previous prostate surgery (radical prostatectomy or transurethral resection of the prostate), radiotherapy (or not, in relation to prostate surgery) and centre. Surgeons and participants were not blind to the treatment received. Non-randomised cohort allocation was participant and/or surgeon preference. SETTING: The trial was set in 28 UK urological centres in the NHS. PARTICIPANTS: Participants were men with urodynamic stress incontinence after prostate surgery for whom surgery was deemed appropriate. Exclusion criteria included previous sling or artificial urinary sphincter surgery, unresolved bladder neck contracture or urethral stricture after prostate surgery, and an inability to give informed consent or complete trial documentation. INTERVENTIONS: We compared male synthetic sling with artificial urinary sphincter. MAIN OUTCOME MEASURES: The clinical primary outcome measure was men's reports of continence (assessed from questions 3 and 4 of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form) at 12 months post randomisation (with a non-inferiority margin of 15%). The primary economic outcome was cost-effectiveness (assessed as the incremental cost per quality-adjusted life-year at 24 months post randomisation). RESULTS: In total, 380 men were included in the randomised controlled trial (n = 190 in each group), and 99 out of 100 men were included in the non-randomised cohort. In terms of continence, the male sling was non-inferior to the artificial urinary sphincter (intention-to-treat estimated absolute risk difference -0.034, 95% confidence interval -0.117 to 0.048; non-inferiority p = 0.003), indicating a lower success rate in those randomised to receive a sling, but with a confidence interval excluding the non-inferiority margin of -15%. In both groups, treatment resulted in a reduction in incontinence symptoms (as measured by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form). Between baseline and 12 months' follow-up, the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score fell from 16.1 to 8.7 in the male sling group and from 16.4 to 7.5 in the artificial urinary sphincter group (mean difference for the time point at 12 months 1.30, 95% confidence interval 0.11 to 2.49; p = 0.032). The number of serious adverse events was small (male sling group, n = 8; artificial urinary sphincter group, n = 15; one man in the artificial urinary sphincter group experienced three serious adverse events). Quality-of-life scores improved and satisfaction was high in both groups. Secondary outcomes that showed statistically significant differences favoured the artificial urinary sphincter over the male sling. Outcomes of the non-randomised cohort were similar. The male sling cost less than the artificial sphincter but was associated with a smaller quality-adjusted life-year gain. The incremental cost-effectiveness ratio for male slings compared with an artificial urinary sphincter suggests that there is a cost saving of £425,870 for each quality-adjusted life-year lost. The probability that slings would be cost-effective at a £30,000 willingness-to-pay threshold for a quality-adjusted life-year was 99%. LIMITATIONS: Follow-up beyond 24 months is not available. More specific surgical/device-related pain outcomes were not included. CONCLUSIONS: Continence rates improved from baseline, with the male sling non-inferior to the artificial urinary sphincter. Symptoms and quality of life significantly improved in both groups. Men were generally satisfied with both procedures. Overall, secondary and post hoc analyses favoured the artificial urinary sphincter over the male sling. FUTURE WORK: Participant reports of any further surgery, satisfaction and quality of life at 5-year follow-up will inform longer-term outcomes. Administration of an additional pain questionnaire would provide further information on pain levels after both surgeries. TRIAL REGISTRATION: This trial is registered as ISRCTN49212975.

Leakage of urine associated with physical exertion (e.g. sporting activities, sneezing or coughing) is common in men who have undergone prostate surgery, but it is difficult to improve. Many men still leak urine 12 months after their prostate surgery and may continue to wear protective pads or sheaths. The most common operation to improve incontinence is implantation of an artificial urinary sphincter. An artificial urinary sphincter is an inflatable cuff that is placed around the urethra, the tube that drains urine from the bladder. The cuff is inflated and compresses the urethra to prevent leaking. When the man needs to pass urine, he must deflate the cuff by squeezing a pump placed in his scrotum, which releases the compression on the urethra and allows the bladder to empty. Recently, a new device, the male sling (made from non-absorbable plastic mesh), has been developed. The sling, which is surgically inserted under the urethra, supports the bladder, but, in contrast to the artificial sphincter, it does not need to be deactivated by a pump and, therefore, the patient does not need to do anything to operate it. A sling is also easier for the surgeon to insert than a sphincter. However, in some men, the sling does not provide enough improvement in incontinence symptoms and another operation, to place an artificial urinary sphincter, is needed. The aim of this study was to determine if the male sling was as effective as the artificial urinary sphincter in treating men with bothersome incontinence after prostate surgery. The study took the form of a randomised controlled trial (the gold standard and most reliable way to compare treatments) in which men were randomised (allocated at random to one of two groups using a computer) to either a male sling or an artificial urinary sphincter operation. We asked men how they got on in the first 2 years after their operation. Regardless of which operation they had, incontinence and quality of life significantly improved and complications were rare. A small number of men did require another operation to improve their incontinence, and it was more likely that an artificial urinary sphincter was needed, rather than another sling operation, if a male sling was not successful. Satisfaction was high in both groups, but it was significantly higher in the artificial urinary sphincter group than in the male sling group. Those who received a male sling were less likely than those who received an artificial urinary sphincter to say that they would recommend their surgery to a friend.

Pelvic floor muscle (PFM) training has received Level-A evidence rating in the treatment of stress urinary incontinence (SUI) in women, based on meta-analysis of numerous randomized control trials (RCTs) and is recommended in many published guidelines. However, the actual regimen of PFM training used varies widely in these RCTs. Hence, to date, the optimal PFM training regimen for achieving continence remains unknown and the following questions persist: how often should women attend PFM training sessions and how many contractions should they perform for maximal effect? Is a regimen of strengthening exercises better than a motor control strategy or functional retraining? Is it better to administer a PFM training regimen to an individual or are group sessions equally effective, or better? Which is better, PFM training by itself or in combination with biofeedback, neuromuscular electrical stimulation, and/or vaginal cones? Should we use improvement or cure as the ultimate outcome to determine which regimen is the best? The questions are endless. As a starting point in our endeavour to identify optimal PFM training regimens, the aim of this study is (a) to review the present evidence in terms of the effectiveness of different PFM training regimens in women with SUI and (b) to discuss the current literature on PFM dysfunction in SUI women, including the up-to-date evidence on skeletal muscle training theory and other factors known to impact on women's participation in and adherence to PFM training.
