RESUMEN

BACKGROUND AND OBJECTIVE: The European, prospective, multicenter SATURN registry was developed to analyze surgical devices for male stress urinary incontinence. The primary objective is the cure rate during follow-up. METHODS: Efficacy, complications, patient-reported outcomes, and prognostic factors are being analyzed at various intervals during 10-yr follow-up. The results at 1-yr follow-up are presented here. KEY FINDINGS AND LIMITATIONS: The cohort included 1046 patients (mean age 70 yr) from 28 centers in nine countries. The main cause of incontinence was radical prostatectomy (83.5%), followed by radiotherapy (4.5%), endourological procedures (9.7%), neurogenic conditions (1.0%), and trauma (0.2%). Some 19.5% of the patients underwent at least one incontinence procedure before registry inclusion. A baseline pad test was performed in 64% of the patients (mean 525 g, range 3.5-3600), urodynamics in 66%, and cystoscopy in 80%. The main implants used were AMS800 (n = 684) and Advance (n = 210) devices, followed by Atoms (n = 63) Victo/Plus (n = 33), ProACT (n = 30), and others (n = 24). A total of 896 patients had 1-yr follow-up data, of whom 164 completed a 1-yr pad test. Self-reported complete incontinence rates at baseline by device were as follows: Advance, 17%; other slings, 33%; ProACT, 0%; AMS800, 49%; other sphincter prosthesis, 100%; and overall group, 44%. The corresponding 1-yr self-reported continence rates were 73%, 37%, 50%, 76%, 11%, and 68%. Some 32% of the patients were still incontinent. Overall, 132 patients had at least one revision. Among the 110 patients with an artificial urinary sphincter (AUS), 122 revisions were performed, while there were 29 revisions for the 22 patients with a sling or ProACT device. International Consultation on Incontinence Questionnaire Short Form and EuroQol 5-dimensions 5-levels scores improved with all devices. CONCLUSIONS AND CLINICAL IMPLICATIONS: AUS implants are used in cases with more severe incontinence and are associated with better outcomes but more revisions than the alternatives. Patients report that every improvement is important. Choices for procedures should be made on the basis of these considerations. PATIENT SUMMARY: We collected data from 29 urology departments in Europe on surgical treatments for patients who suffer from incontinence during exercise, sneezing, and coughing. Results after 1 year show that an artificial urinary sphincter has the best outcomes overall and for patients with heavy urine loss. However, this surgery also requires more revisions. Patients report that every improvement in continence is important to them.

RESUMEN

AIMS: To confirm the improved performance of the micro-hole zone catheter (MHZC) compared to a conventional eyelet catheter (CEC) in male users of clean intermittent catheterizations (CICs). METHODS: Male self-catheterizing subjects, who used hydrophilic sleeved soft/flexible CIC as the only bladder emptying method, were enrolled into a multi-center, randomized, cross-over study performed across six European sites. Subjects tested the MHZC, featuring a drainage zone with 120 micro-holes and a CEC with two eyelets. The study consisted of four study visits (V0-V3), during which endpoints related to catheter performance (urinary flow-stops, bladder emptying, and intra-catheter pressure) were measured and two 4-week test periods at home (T1 and T2) where dipstick hematuria and user perception between catheters were evaluated. RESULTS: Seventy-three male subjects with non-neurogenic and neurogenic bladder dysfunction (3:2) were enrolled. On average, catheterizations with the MHZC led to close to mean zero flow-stops compared to ≥1 flow-stops with the CEC, during both HCP- and self-led catheterizations (both p < 0.001). Residual urine at first flow-stop was significantly reduced for the MHZC compared to CEC (p = 0.001 and p = 0.004, for HCP- and self-led catheterizations, respectively). This was substantiated by a significantly smaller pressure peak at first flow-stop, a proxy for minimized mucosal suction (both HCP- and self-led catheterizations, p < 0.001). After home-use catheterizations, dipstick hematuria was comparable between catheters, whereas catheterizations were associated with significantly improved perception in favor of MHZC regarding bladder emptying, less blocking sensation, and improved hygienic catheterization compared to the CEC. CONCLUSION: This study confirmed the evidence of improved bladder emptying with the MHZC compared to a CEC without the need to reposition the catheter. The MHZC therefore offers an enhanced benefit for the dependent CIC user securing complete bladder emptying in an uninterrupted free flow and reducing the need to reposition the catheter during emptying.

RESUMEN

Objective: To examine the safety and efficacy of prostatic urethral lift (PUL) in acute urinary retention (AUR) patients within a controlled (PULSAR) and real-world setting (Real-World Retrospective study). Materials and methods: PULSAR was a 12-month prospective study of PUL in AUR patients (n = 51) performed at six centres in the United Kingdom; enrolled BPH patients aged ≥50 years, with prostate volume of ≤100 cc. AUR was defined as being catheter dependent with at least one prior failed trial without catheter (TWOC) while on an alpha-blocker. RWR consisted of 3226 consecutive PUL patients across 22 international sites treated between July 2017 and March 2020; 469 of whom were in urinary retention (RWRr), that is, catheter-dependent at the time of their procedure. Symptom response, uroflow and catheter independence rates were compared between PULSAR and RWRr subjects. A logistical regression model was constructed to evaluate patient baseline and dynamic factors predicting success after the procedure. Results: Seventy-three percent of PULSAR subjects were catheter independent and free from surgical reintervention at 12 months post-PUL. Success was associated with higher voiding efficiency during the perioperative period. Slightly higher catheter-independent rates (80%) were seen in RWRr patients; variables that influenced success included age <70 years, lower baseline prostate-specific antigen (PSA), lower baseline post-void residual (PVR) and shorter pre-procedural catheter duration. Logistic regression of the combined PULSAR and RWRr retention groups revealed that procedural age <70 years and higher bladder voiding efficiency (BVE) were associated with success. Conclusions: Lower baseline PSA and PVR, younger age and shorter pre-procedure catheter durations drove successful outcomes in AUR patients undergoing PUL. Post-PUL voiding efficiencies may help ascertain long-term response to treatment.

RESUMEN

BACKGROUND: Evidence shows that intermittent catheterisation (IC) for bladder emptying is linked to urinary tract infections (UTIs) and poor quality of life (QoL). AIM: To investigate the association between UTI risk factors and QoL and patient-reported UTIs respectively. METHODS: A survey was distributed to IC users from 13 countries. FINDINGS: Among 3464 respondents, a significantly poorer QoL was observed when experiencing blood in the urine, residual urine, bowel dysfunction, recurrent UTIs, being female, and applying withdrawal techniques. A lower UTI risk was found when blood was not apparent in urine (RR: 0.63; 95% CI: 0.55-0.71), the bladder was perceived empty (RR: 0.83; 95% CI: 0.72-0.96), not having bowel dysfunction (RR: 0.86; 95% CI: 0.76-0.98), and being male (RR: 0.70; 95% CI: 0.62-0.79). CONCLUSION: This study underlines the importance of risk factors and their link to QoL and UTIs, highlighting the need for addressing symptoms before UTIs become problematic.

RESUMEN

OBJECTIVE: To estimate the cost-effectiveness of single-use hydrophilic-coated intermittent catheters (HCICs) versus single-use uncoated intermittent catheters (UICs) for urinary catheterization. METHODS: The evaluation took a UK national health service (NHS) perspective. The population of interest were people using intermittent catheters, with either a spinal cord injury or multiple sclerosis. A Markov model was developed that estimated costs and clinical evidence over the lifetime of a hypothetical cohort and applied health-related quality-of-life estimates. Model inputs were sourced from published evidence, including a network meta-analysis to inform the treatment effect (reduction in catheter-associated urinary tract infections [CAUTIs]), and were supported by expert opinion. The model outputs included per-patient lifetime costs, quality-adjusted life years (QALYs), and the incremental cost effectiveness ratio (ICER). Event counts were also produced. RESULTS: Using HCICs instead of UICs could prevent seven CAUTI events per patient over a lifetime horizon (1.8 requiring secondary care). Overall, lifetime use of HCICs is £3,183 more expensive than use of UICs per patient. However, for these additional costs, 0.55 QALYs are gained. The ICER is £5,755 per additional QALY gained. Key drivers of the model results were identified and subject to sensitivity analyses. The results were found to be robust to parameter uncertainty. CONCLUSION: HCICs are likely to be a cost-effective alternative to UICs, a result driven by substantial reductions in the number of CAUTIs. Their adoption across clinical practice could avoid a substantial number of infections, freeing up resources in the NHS and reducing antibiotic use in urinary catheter users.


A new economic model was developed from a United Kingdom National Health Service perspective, to explore whether hydrophilic-coated intermittent catheters would be "worth" introducing for intermittent catheter users with either a spinal cord injury or multiple sclerosis. More specifically, costs were analyzed alongside clinical evidence and health-related quality-of-life data to investigate whether hydrophilic-coated intermittent catheters would offer a notable health benefit when compared with uncoated intermittent catheters for the assessed population, whilst keeping costs to the National Health Service sufficiently low. Model inputs were sourced from published evidence where possible, and experts were consulted otherwise. The results showed that, whilst lifetime use of hydrophilic-coated intermittent catheters is £3,183 more expensive than use of uncoated intermittent catheters per patient, the health benefit with hydrophilic-coated intermittent catheters offsets these costs, by definition a cost-effective result. This means that hydrophilic-coated intermittent catheters are likely to be a cost-effective alternative to uncoated intermittent catheters. Their adoption across clinical practice could avoid a substantial number of infections, thereby freeing up healthcare resources in the National Health Service and reducing antibiotic use in urinary catheter users.

RESUMEN

BACKGROUND: Recommendations for the management of pain related to pelvic mesh implants are still under development. One limitation that has impeded progress in this area is that mesh-related pain has not been consistently defined or measured. Here, we reviewed the ways in which pain associated with pelvic mesh implants has been measured, and mapped the ways in which these existing measures capture the construct. METHODS: First, we reviewed existing accounts of the pain associated with pelvic mesh implants to develop a multifaceted construct definition, which includes aspects related to pain intensity, timing, body location, phenomenological qualities, impact/interference with daily living, and patient expectations and beliefs. Next, we reviewed the ways that the construct has been measured in the extant literature. RESULTS: Within 333 eligible studies, 28 different assessments of pain associated with pelvic mesh were identified, and 61% of studies reported using more than one measurement tool. Questionnaire measures included measures designed to assess urological and/or pelvic symptoms, generic measures and unvalidated measures. We did not identify any validated questionnaire measures designed to assess pain associated with pelvic mesh implants. The phenomenological, location, and expectation/belief components of the construct were not captured well by the identified questionnaire measures, and there is no evidence that any of the identified measures have appropriate psychometric properties for the assessment of pain related to pelvic mesh implants. CONCLUSIONS: We recommend further qualitative research regarding women's experiences of pelvic mesh-related pain assessment, and the development of a condition-specific patient reported outcome measure.

RESUMEN

BACKGROUND: Various washout policies are widely used in adults living with long-term catheters (LTC). There is currently insufficient evidence on the benefits and potential harms of prophylactic LTC washout policies in the prevention of blockages and other LTC-related adverse events, such as urinary tract infections. CATHETER II tests the hypothesis that weekly prophylactic LTC washouts (normal saline or citric acid) in addition to standard LTC care reduce the incidence of catheter blockage requiring intervention compared to standard LTC care only in adults living with LTC. METHODS: CATHETER II is a pragmatic three-arm open multi-centre superiority randomised controlled trial with an internal pilot, economic analysis, and embedded qualitative study. Eligible participants are adults aged ≥ 18 years, who have had a LTC in use for ≥ 28 days, have no plans to discontinue the use of the catheter, are able to undertake the catheter washouts, and complete trial documentation or have a carer able to help them. Participants are identified from general practitioner practices, secondary/tertiary care, community healthcare, care homes, and via public advertising strategies. Participants are randomised 1:1:1 to receive a weekly saline (0.9%) washout in addition to standard LTC care, a weekly citric acid (3.23%) washout in addition to standard LTC care or standard LTC care only. Participants and/or carers will receive training to administer the washouts. Patient-reported outcomes are collected at baseline and for 24 months post-randomisation. The primary clinical outcome is catheter blockage requiring intervention up to 24 months post-randomisation expressed per 1000 catheter days. Secondary outcomes include symptomatic catheter-associated urinary tract infection requiring antibiotics, catheter change, adverse events, NHS/ healthcare use, and impact on quality of life. DISCUSSION: This study will guide treatment decision-making and clinical practice guidelines regarding the effectiveness of various prophylactic catheter washout policies in men and women living with LTC. This research has received ethical approval from Wales Research Ethics Committee 6 (19/WA/0015). TRIAL REGISTRATION: ISRCTN ISRCTN17116445 . Registered prospectively on 06 November 2019.

RESUMEN

This study assessed the feasibility of dynamic transperineal ultrasound (TPUS) pre/post-radical prostatectomy (RP). Ninety-eight patients were scanned pre-operatively and at four time-points post-operatively. TPUS was performed in 98 patients using an abdominal transducer at rest, during pelvic floor contraction (PFC) and Valsalva (VS) maneuver in supine and standing positions. Urodynamic evaluations included bladder neck angle at rest/PFC/VS, and degree of bladder neck movement. Pre-operative and post-operative measurements were technically feasible in >85% (supine) and >90% (standing) of patients. TPUS offers a reliable non-invasive dynamic assessment of the pelvic floor post-prostatectomy and may prove a useful adjunct for guiding exercises to preserve continence.

RESUMEN

BACKGROUND: Daily, low-dose antibiotic prophylaxis is the current standard care for women with recurrent urinary tract infection. Emerging antimicrobial resistance is a global health concern, prompting research interest in non-antibiotic agents such as methenamine hippurate, but comparative data on their efficacy and safety are lacking. OBJECTIVE: To assess the clinical effectiveness and cost-effectiveness of methenamine hippurate (Hiprex®; Mylan NV, Canonsburg, PA, USA) compared with current standard care (antibiotic prophylaxis) for recurrent urinary tract infection prevention in adult women. DESIGN: Multicentre, pragmatic, open-label, randomised, non-inferiority trial of 12 months' treatment with the allocated intervention, including an early, embedded qualitative study and a 6-month post-treatment observation phase. The predefined non-inferiority margin was one urinary tract infection per person-year. SETTING: Eight UK NHS secondary care sites. PARTICIPANTS: A total of 240 adult women with recurrent urinary tract infection requiring preventative treatment participated in the trial. INTERVENTIONS: A central randomisation system allocated participants 1 : 1 to the experimental (methenamine hippurate: 1 g twice daily) or control (once-daily low-dose antibiotics: 50/100 mg of nitrofurantoin, 100 mg of trimethoprim or 250 mg of cefalexin) arm. Crossover between treatment arms was permitted. MAIN OUTCOME MEASURES: The primary clinical outcome was incidence of symptomatic antibiotic-treated urinary tract infection during the 12-month treatment period. Cost-effectiveness was assessed by incremental cost per quality-adjusted life-year gained, extrapolated over the patient's expected lifetime using a Markov cohort model. Secondary outcomes included post-treatment urinary tract infections, total antibiotic use, microbiologically proven urinary tract infections, antimicrobial resistance, bacteriuria, hospitalisations and treatment satisfaction. RESULTS: Primary modified intention-to-treat analysis comprised 205 (85%) randomised participants [102/120 (85%) participants in the antibiotics arm and 103/120 (86%) participants in the methenamine hippurate arm] with at least 6 months' data available. During treatment, the incidence rate of symptomatic, antibiotic-treated urinary tract infections decreased substantially in both arms to 1.38 episodes per person-year (95% confidence interval 1.05 to 1.72 episodes per person-year) for methenamine hippurate and 0.89 episodes per person year (95% confidence interval 0.65 to 1.12 episodes per person-year) for antibiotics (absolute difference 0.49; 90% confidence interval 0.15 to 0.84). This absolute difference did not exceed the predefined, strict, non-inferiority limit of one urinary tract infection per person-year. On average, methenamine hippurate was less costly and more effective than antibiotics in terms of quality-adjusted life-years gained; however, this finding was not consistent over the longer term. The urinary tract infection incidence rate 6 months after treatment completion was 1.72 episodes per year in the methenamine hippurate arm and 1.19 in the antibiotics arm. During treatment, 52% of urine samples taken during symptomatic urinary tract infections were microbiologically confirmed and higher proportions of participants taking daily antibiotics (46/64; 72%) demonstrated antibiotic resistance in Escherichia coli cultured from perineal swabs than participants in the methenamine hippurate arm (39/70; 56%) (p-value = 0.05). Urine cultures revealed that during treatment higher proportions of participants and samples from the antibiotic arm grew E. coli resistant to trimethoprim/co-trimoxazole and cephalosporins, respectively. Conversely, post treatment, higher proportions of participants in the methenamine hippurate arm (9/45; 20%) demonstrated multidrug resistance in E. coli isolated from perineal swabs than participants in the antibiotic arm (2/39; 5%) (p = 0.06). All other secondary outcomes and adverse events were similar in both arms. LIMITATIONS: This trial could not define whether or not one particular antibiotic was more beneficial, and progressive data loss hampered economic evaluation. CONCLUSIONS: This large, randomised, pragmatic trial in a routine NHS setting has clearly shown that methenamine hippurate is not inferior to current standard care (daily low-dose antibiotics) in preventing recurrent urinary tract infections in women. The results suggest that antimicrobial resistance is proportionally higher in women taking prophylactic antibiotics. RECOMMENDATIONS FOR RESEARCH: Future research should include evaluation of other non-antibiotic preventative treatments in well-defined homogeneous patient groups, preferably with the comparator of daily antibiotics. TRIAL REGISTRATION: This trial is registered as ISRCTN70219762 and EudraCT 2015-003487-36. FUNDING: This project was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 23. See the NIHR Journals Library website for further project information.


Women with recurrent urine infections often require preventative treatment to reduce the frequency of infection episodes. Daily low-dose antibiotic medication is a guideline-recommended treatment option for these women. There is increasing concern globally regarding antibiotic-resistant infections, which has led researchers to look at alternative treatments. This trial was conducted to find out whether or not taking an alternative treatment that is not an antibiotic [i.e. methenamine hippurate (Hiprex®; Mylan NV, Canonsburg, PA, USA)] was as effective as the standard daily low-dose antibiotics. A total of 240 women from across the UK took part in the trial. They were divided equally into two groups; half of the women were given methenamine hippurate and the other half were given standard low-dose antibiotics. Both treatments were prescribed to be taken every day for 1 year. To make a fair comparison, people were put into the two groups at random using a computer program. Aspects of the trial that could be improved were identified through telephone interviews with patients and recruiting staff. Feedback from these telephone interviews helped to ensure the successful conduct of the trial. Patients were followed up for 18 months, comprising the 12 months when they were taking treatment and a 6-month follow-up phase after they had finished treatment. We found that the non-antibiotic option of methenamine hippurate was no worse than the current standard treatment of daily antibiotics in preventing urinary tract infection episodes in adult women. For both treatments, patients expressed high levels of satisfaction. One advantage of the methenamine hippurate treatment was that infecting bacteria were slightly less likely to develop resistance to antibiotics. We also evaluated health-care costs of both treatments and found that methenamine hippurate seemed worthwhile to the NHS in the short term, but there was uncertainty over longer-term costs and benefits. These results will help patients with repeated urinary tract infections to decide on treatment options, particularly if they want to avoid prolonged courses of preventative antibiotics.

RESUMEN

OBJECTIVE: To test and compare the efficacy of methenamine hippurate for prevention of recurrent urinary tract infections with the current standard prophylaxis of daily low dose antibiotics. DESIGN: Multicentre, open label, randomised, non-inferiority trial. SETTING: Eight centres in the UK, recruiting from June 2016 to June 2018. PARTICIPANTS: Women aged ≥18 years with recurrent urinary tract infections, requiring prophylactic treatment. INTERVENTIONS: Random assignment (1:1, using permuted blocks of variable length via a web based system) to receive antibiotic prophylaxis or methenamine hippurate for 12 months. Treatment allocation was not masked and crossover between arms was allowed. MAIN OUTCOME MEASURE: Absolute difference in incidence of symptomatic, antibiotic treated, urinary tract infections during treatment. A patient and public involvement group predefined the non-inferiority margin as one episode of urinary tract infection per person year. Analyses performed in a modified intention-to-treat population comprised all participants observed for at least six months. RESULTS: Participants were randomly assigned to antibiotic prophylaxis (n=120) or methenamine hippurate (n=120). The modified intention-to-treat analysis comprised 205 (85%) participants (antibiotics, n=102 (85%); methenamine hippurate, n=103 (86%)). Incidence of antibiotic treated urinary tract infections during the 12 month treatment period was 0.89 episodes per person year (95% confidence interval 0.65 to 1.12) in the antibiotics group and 1.38 (1.05 to 1.72) in the methenamine hippurate group, with an absolute difference of 0.49 (90% confidence interval 0.15 to 0.84) confirming non-inferiority. Adverse reactions were reported by 34/142 (24%) in the antibiotic group and 35/127 (28%) in the methenamine group and most reactions were mild. CONCLUSION: Non-antibiotic prophylactic treatment with methenamine hippurate might be appropriate for women with a history of recurrent episodes of urinary tract infections, informed by patient preferences and antibiotic stewardship initiatives, given the demonstration of non-inferiority to daily antibiotic prophylaxis seen in this trial. TRIAL REGISTRATION: ISRCTN70219762.

RESUMEN

OBJECTIVES: To report the British Association of Urological Surgeon's (BAUS) guidance on the assessment and management of female voiding dysfunction. METHODS: A contemporary literature search was conducted to identify the evidence base. The BAUS Section of Female, Neurological and Urodynamic Urology (FNUU) Executive Committee formed a guideline development group to draw up and review the recommendations. Where there was no supporting evidence, expert opinion of the BAUS FNUU executive committee, FNUU Section and BAUS members, including urology consultants working in units throughout the UK, was used. RESULTS: Female patients with voiding dysfunction can present with mixed urinary symptoms or urinary retention in both elective and emergency settings. Voiding dysfunction is caused by a wide range of conditions which can be categorized into bladder outlet obstruction (attributable to functional or anatomical causes) or detrusor underactivity. Guidance on the assessment, investigation and treatment of women with voiding dysfunction and urinary retention, in the absence of a known underlying neurological condition, is provided. CONCLUSION: Wa have produced a BAUS approved consensus on the management pathway for female voiding dysfunction with the aim to optimize assessment and treatment pathways for patients.

RESUMEN

PURPOSE OF REVIEW: A continent vesicostomy represents a useful alternative for adult patients with impaired bladder emptying who are unable to perform clean intermittent (self-) catheterization through the urethra. In a pediatric setting, there exists a vast experience in these procedures. But experience with continent catheterizable vesicostomies is less abundant in adult patients. We want to give an overview and discuss recent literature about catheterizable conduits in the adult population. RECENT FINDINGS: Adult patients who undergo continent vesicostomy comprise a diverse cohort. Because of this very heterogeneous population, it can be difficult to make an objective analysis and draw conclusions on both the success rate and complication rate of these diversions. We will discuss short- and long-term surgical outcomes and changes in quality of life after the procedure in these patients. SUMMARY: A continent vesicostomy is a valuable and durable reconstructive technique for adult patients with impaired bladder emptying. Surgery can be challenging and a better knowledge of complications can help with patient counseling. In the future we hope that minimally invasive surgery will decrease the morbidity of such surgery and hopefully also improve functional outcomes and diminish the complication rate.

RESUMEN

Prostate cancer is the second most common male cancer, and radical prostatectomy is a highly effective treatment for intermediate and high-risk disease. However, post-prostatectomy urinary incontinence remains a major functional side-effect in patients undergoing radical prostatectomy. Despite recent improvements in preoperative imaging quality and surgical techniques, it remains challenging to predict or prevent occurrence of this complication. The aim of this research was to review the current published literature on pre- and postoperative imaging evaluation of the prostate and pelvic structures, to identify added value in the prediction of post-prostatectomy urinary incontinence. A computerized bibliographic search of the PubMed library was carried out to identify imaging-based articles evaluating the pelvic floor and surrounding structures pre- and/or postradical prostatectomy to predict post-prostatectomy urinary incontinence. A total of 32 articles were included. Of these, 29 papers assessed the importance of magnetic resonance imaging evaluation, with a total of 16 parameters evaluated. The most common parameters were intravesical protrusion, the membranous urethral length, prostatic volume and periurethral fibrosis. Preoperative membranous urethral length and its preservation after surgery showed the strongest correlation with urinary incontinence. Three studies evaluated ultrasound, with all carried out postoperatively. This technique benefits from a dynamic evaluation, and the results are promising for proximal urethral hypermobility and the degree of bladder neck funneling on the Valsalva maneuver. Several imaging studies evaluated the predictors of post-prostatectomy urinary incontinence, with preoperative membranous urethral length offering the most promise. However, the current literature is limited by the single-center nature of studies, and the heterogeneity in patient populations and methodologies used.

RESUMEN

Injuries to the bladder and ureter are uncommon but usually require prompt urological management. Due to their infrequent nature, Urologists maybe unfamiliar with managing these acute problems and may not work in specialist centres with readily available expertise in open and abdominal surgery. We aim to provide advice in the form of a consensus statement led by the Female, Neurological and Urodynamic Urology (FNUU) Section of the British Association of Urological Surgeons (BAUS), in consultation with BAUS members and consultants working in units throughout the UK, to create a comprehensive management pathway and a series of statements to aid clinicians.

RESUMEN

OBJECTIVE: To look at best evidence and expert opinion to provide advice in the form of a consensus statement lead by Female, Neurological and Urodynamic Urology (FNUU) section of the British Association of Urological Surgeons (BAUS) in conjunction with the British Association of Urological Nurses (BAUN). METHODS: Initially a literature search was performed with incorporation of aspects of the existing guidance and further informed by UK best practice by core members of the group. The document then underwent reviews by the FNUU Executive Committee members, the BAUN executive committee, a separate experienced urologist and presented at the BAUS annual meeting 2020 to ensure wider feedback was incorporated in the document. RESULTS: Complications of long-term indwelling catheters include catheter-associated urinary tract infections (CAUTI), purple urine bag syndrome, catheter blockages, bladder spasms (causing pain and urinary leakage), loss of bladder capacity, urethral erosion ("catheter hypospadias")/dilatation of bladder outlet and chronic inflammation (metaplasia and cancer risk). CONCLUSIONS: We have provided a list of recommendations and a troubleshooting table to help with the management of the complications of long term catheters.

RESUMEN

CONTEXT: Nocturia is a prevalent symptom with varied aetiology and no consensus on treatment options. OBJECTIVE: We systematically reviewed evidence comparing the benefits and harms of various treatment options for nocturia or nocturnal incontinence in women. EVIDENCE ACQUISITION: Literature search was performed using Embase, Medline, and Cochrane databases (from 1 January 1946 to 26 September 2017), following the methods detailed in the Cochrane Handbook. The protocol was registered with PROSPERO. Certainty of evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. EVIDENCE SYNTHESIS: The literature search identified 3573 citations, of which 11 full-text articles were included. Three studies on desmopressin and four on antimuscarinics provided evidence of improving nocturia symptoms. Four studies on behavioural treatment provided limited evidence and controversial results. One study on oestrogen did not prove the benefit of any mode of administration, and one small study on functional magnetic stimulation provided some evidence of effectiveness in nocturia. One randomised controlled trial (RCT; 141 participants) reported a statistically significant difference between the desmopressin and placebo groups (desmopressin patients experienced 0.75 [95% confidence interval {CI} 0.47-1.03] nocturia episodes less than those experience by the placebo group; certainty of evidence = low). The only RCT on antimuscarinics in women with nocturia reported that oxybutynin reduced the number of nocturia episodes by 0.3 (95% CI -0.02 to 0.62) versus placebo. In one RCT comparing tolterodine with the combination of tolterodine with behavioural therapy, there was significant change from baseline nocturnal incontinence episodes in both groups. CONCLUSIONS: There is some evidence that desmopressin and antimuscarinics are effective treatment options for nocturia; however, there is very limited evidence for other treatment options. The findings should be interpreted with caution as there were some methodological flaws in the included studies, particularly outcome heterogeneity. PATIENT SUMMARY: This review identified several medical treatments for nocturia in women, such as desmopressin and antimuscarinics, which appear to improve the severity of the condition.

RESUMEN

PURPOSE OF REVIEW: The aim of the present report was to review the recent evidences regarding the use of artificial urinary sphincter (AUS) in adult females. RECENT FINDINGS: While the excellent functional outcomes of AUS in female patients with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD) have been reported for decades, its use has remained confidential in most countries likely due to its challenging implantation and inherent morbidity. Over the past few years, laparoscopic and, more recently, robotic techniques of AUS implantation in female patients have been described with promising perioperative outcomes. As a result, the use of AUS has increased in several countries. The indications are mostly recurrent or persistent SUI after previous anti-incontinence procedures and neurogenic SUI. Owing to its unique potential to restore continence while maintaining low outlet resistance during the voiding phase, AUS may be of special interest in female patients with detrusor underactivity. High level of evidence data from trials which are underway, along with developments in robotic surgery and technological refinements of the device, may well, almost 50 years after its introduction, give to the AUS its momentum as a major contributor in the female SUI armamentarium. While the use of AUS in female patients has been restricted to some countries and a few high-volume centers, it has started spreading again over the past few years, thanks to the rise of minimally invasive approaches which facilitate its implantation, and this is yielding promising outcomes.

RESUMEN

History A 28-year-old man presented with lifelong anejaculation, which had become an issue because of family planning. The patient had a history of normal erections and experienced the sensation of orgasm without ever ejaculating. On physical examination, both testes were present in the scrotum, with normal dimensions and a normal epididymis bilaterally. The patient had a slightly tender left testicle, and digital rectal examination findings were normal. The patient underwent further investigation for the possibility of retrograde ejaculation with urine cytology, the results of which were negative. Genetic testing was performed to exclude Y chromosome microdeletions. Serum-luteinizing and follicle-stimulating hormone levels were normal, with a borderline low level of testosterone (7.6 nmol/L; normal range, 8.0-29.0 nmol/L). All other pertinent laboratory results were noncontributory. Pelvic MRI was requested to exclude an anatomic cause of anejaculation. MRI was performed in accordance with the standard clinical prostate protocol, with a dynamic contrast material-enhanced study. CT of the upper abdomen was also performed. The patient subsequently underwent cystoscopy, which revealed an intravesicular fluid-filled mass near the left ureteric orifice.
