Serum proteomic pattern in female stress urinary incontinence.

The pathophysiology of Stress Urinary Incontinence (SUI) is poorly understood. The aim of this study was to identify the serum proteomic profile in patients with SUI and to replicate findings from a preceding study in which a significant difference in the urinary proteome was identified. Serum samples were collected from 38 patients (19 SUI; 19 matched, continent controls). Sample preparation included serum albumin depletion, in-solution enzymatic digestion of proteins applying a combination of Gluc-C and trypsin and peptide separation using nano High Performance Liquid Chromatography. Label-free quantitation of peptides and proteins was performed after triplicate measurements using quadrupole time-of-flight mass spectrometry. Peptide identification was achieved by searching the Human SwissProt Database using Mascot and X!Tandem. Main outcome measure was the relative abundance of each detected protein in serum. Of 7012 identified proteins, 33 proteins were induced (detected in SUI, not in controls) and five proteins were depleted (detected in controls, not in SUI). All depleted proteins play a role in immune/DNA damage response. Induced proteins are involved in inflammatory response, response to cellular stress, coagulation and cytoskeleton stability/ motility. Plasma serine protease inhibitor (SERPINA5) was found induced and previously also showed a higher abundance in urine samples of SUI patients. Data are available via ProteomeXchange with identifier PXD008553.

Retropubic versus transobturator tension-free vaginal tape (TVT vs TVT-O): Five-year results of the Austrian randomized trial.

AIMS: To compare outcomes of the retropubic versus the transobturator tension-free vaginal tape (TVT vs TVT-O) at 5 years. METHODS: A total of 569 women undergoing surgery for primary stress incontinence were randomized to receive a retropubic or a transobturator tensionfree vaginal tape (TVT or TVT-O). Follow-up at 5 years included clinical examination, urodynamic studies and quality of life. The primary outcome measure was continence defined as a negative cough stress test at a volume of 300 mL. Secondary outcomes included urodynamic parameters, complications and quality of life.ClinicalTrials.gov (NCT 0041454). RESULTS: Three hundred and thirty-one patients (59%) were evaluated at 5 years (277 were seen, examined and completed questionnaires; 54 only completed questionnaires). No significant differences were seen in rates of a negative cough stress test (83% vs 76%, respectively), urodynamic parameters and complications. Quality-of-life improved significantly in both groups, without significant differences between the groups. Erosion rates were 5.2% and 4.5%, and reoperation rates were 4.1% and 3.2% respectively. CONCLUSIONS: At 5 years, subjective and objective results after TVT and TVT-O are stable and similar, without statistical significant differences between the procedures. Major long-term problems appear rare.

Anterior colporrhaphy: a standard operation? Systematic review of the technical aspects of a common procedure in randomized controlled trials.

INTRODUCTION: Anterior colporrhaphy (AC) is considered a standard procedure and is performed all over the world. However, not a single step of the procedure has ever been truly standardized and the rates of failure show a wide range in the literature from 0% up to 92%. The aim of this systematic review was to evaluate the differences in technique and procedure worldwide. METHODS: We performed a systematic literature search up to March 2016 using the MeSH terms "(anterior AND (colporrhaph* or colporhaph* or repair* or cystocel*)" using Preferred Reporting Items for Sytematic Reviews and Meta-Analyses (PRISMA). Only randomized controlled trials (RCT) were included in the systematic review. A 14-point checklist was used to assess the quality of surgery undertaken in each RCT. RESULTS: Forty RCTs from all over the world were included in the review. The indication for AC was urinary incontinence and/or pelvic organ prolapse. A detailed description of colporrhaphy was not provided even in the well-conducted RCTs. The review showed differences in each step of the procedure, in perioperative care, in anesthesia and in surgeon' experience. CONCLUSION: Our results highlight the problems concerning AC with the great range in postoperative outcomes. There is diversity in the anatomical structures used in the repair, in perioperative care and in the procedure itself.

CONSORT and the internal validity of randomized controlled trials in Female Pelvic Medicine.

AIMS: To investigate authors' adherence to the CONSORT reporting guideline for randomized controlled trials (RCTs) in the sub-specialty Female Pelvic Medicine and to detect any changes in adherence between the years 2008 and 2013. METHODS: Bibliometric study. We included Female Pelvic Medicine RCTs published in 2008 and 2012-2013 in 10 journals. Full-text versions of RCTs for the inclusion of the CONSORT checklist items Randomization, Allocation, Blinding, and Participants' flowchart were screened. Each CONSORT checklist item was categorized for each included RCT as either "complete reporting", "insufficient reporting", "no reporting," or "not applicable". We screened the "Instructions to authors" for the requirement to adhere to CONSORT. RESULTS: We included 94 Female Pelvic Medicine RCTs for analysis. Most RCTs in 2008, 2012, and 2013 were published by IUJ (n =n39), followed by NAU (n = 13), GREEN (n = 12), European Urology (n = 8), FMPRS (n = 6), AJOG (n = 4), Urology (n = 3), NEJM (n = 3), Lancet (n = 1), and BJOG (n = 1). Proportion of RCTs in the category "complete reporting" comparing 2008 and 2013 was (47 and 70%) for Randomization, (18 and 45%) for Allocation, and (29 and 52%) for Blinding; a flowchart was presented in (71 and 91%). The increase was not statistically significant in any of the investigated CONSORT items. CONCLUSIONS: Complete reporting of Female Pelvic Medicine RCTs has increased between 2008 and 2013. However, there are still a relevant number of published RCTs, which do not fulfill these criteria. Reporting according to the CONSORT guidelines should be further encouraged to improve internal validity of Female Pelvic Medicine RCTs. Neurourol.

The explicit mentioning of reporting guidelines in urogynecology journals in 2013: A bibliometric study.

AIMS: Poor reporting of research may limit critical appraisal and reproducibility, whereas adherence to reporting guidelines (RG) can guarantee completeness and transparency. We aimed to determine the explicit citing of RGs (CONSORT, PRISMA, STROBE) in urogynecology articles in 2013, the requirements of relevant journals and a potential difference between urogynecology and general gynecology journals. METHODS: All urogynecologic articles published between January and December 2013 in the journals NAU, IUJ, FPMRS, GREEN, AJOG, and BJOG were included. Issues were searched for systematic reviews, RCTs, cohort studies, case-control studies and cross-sectional studies. Each electronic article was searched for the term PRISMA, CONSORT, or STROBE according to the study design. Instructions to Authors of the six journals were screened for requirement of using RGs. RESULTS: We included 296 articles (243 observational studies, 40 RCTs, and 13 systematic reviews). The use of PRISMA guidelines was explicitly declared in 54% of systematic reviews, CONSORT guidelines were referenced in 25% of RCTs and STROBE in 1.2% of observational studies. The use of CONSORT is required by all journals except FPMRS. PRISMA and STROBE are only compulsory in the journals GREEN, AJOG, and BJOG. The overall rate of explicit mentioning of RGs comparing urogynecology and general gynecology journals was 6.7% versus 7.1%, respectively. CONCLUSIONS: The explicit mentioning of RGs was on a relatively low level. A slightly higher adherence was recognized among general gynecology journals compared to urogynecology journals. Stronger efforts should be taken to further promote the use of RGs in urogynecology.

Surgical management of urethral diverticula in women: a systematic review.

Urethral diverticula (UD) are pouch-like outgrowths of the urethral lumen and surgery is by far the most common approach in symptomatic patients. The aim of this systematic review was to evaluate surgical techniques and outcomes in adult women with urethral diverticula. Our secondary objective was to determine the types of study designs. A systematic review of the literature was conducted. Medline, Cinahl and Embase were used as data sources. One hundred and eight studies, including 1,947 patients, remained for final analysis. We summarised 40 single case reports and 68 case series. Overall, transvaginal resection of the UD ± reconstruction was performed in the majority of patients (84 %), followed by marsupialisation (3.8 %) and transurethral endoscopic unroofing (2.0 %). Various other surgical techniques were reported in 181 out of 1,858 cases (9.7 %). Nineteen studies, dealing with 584 patients in all, evaluated a combination of vaginal diverticulectomy with an additional surgical procedure. Fifty-six out of 108 studies (52 %) documented the resolution of symptoms, describing 717 out of 1,044 patients in all being completely symptom-free after surgery. Only 50 out of 108 studies (46.2 %) provided detailed information on the length of follow-up, but showed a poor reporting standard regarding prognosis. Complications were studied only selectively. Because of the inconsistency of these data, it was impossible to analyse them collectively. There were no comparative studies on the different types of surgery in women with urethral diverticula. Overall, the non-comparative nature of the current evidence on the surgical management of UD does not allow any accurate estimation of success and complication rates.

Pelvic floor symptoms in female cyclists and possible remedies: a narrative review.

INTRODUCTION AND HYPOTHESIS: Cycling has become a popular athletic activity worldwide and can lead to genital and pelvic floor dysfunction. This review summarizes the current body of evidence about the epidemiology of genital and pelvic floor symptoms in female cyclists, the therapy, and preventive interventions. METHODS: Two electronic meta-databases, OvidSP™ and Deutsches Institut für Medizinische Dokumentation und Information (DIMDI), comprising 40 individual databases, were searched for studies that described genital and pelvic floor symptoms in association with cycling and studies that tested possible therapies and prophylactic measures. For the literature search we explored the search terms "female", "bicycling", "pelvic floor", "lower urinary tract symptoms", and "vulvar diseases". RESULTS: The search retrieved 1,219 articles, leaving 763 articles after removal of duplicates, and finally 12 articles eligible for review. We assessed 10 observational and 2 experimental studies. Genital and pelvic floor symptoms related to bicycling were pain, tenderness, neuropathy, urological dysfunction and skin lesions. Broader and conventionally shaped saddles were associated with fewer symptoms compared with cut-out saddle designs. CONCLUSION: The quality of existing studies is generally low, but there is evidence that female cyclists suffer from similar problems to male cyclists, ranging from minor skin lesions to severe sequelae such as pain and neurological deficiencies.

Urinary proteomic pattern in female stress urinary incontinence: a pilot study.

INTRODUCTION AND HYPOTHESIS: Previous studies aiming to identify specific pre-defined urine protein biomarkers for stress urinary incontinence (SUI) have not identified clinically important differences. The hypothesis of our study was that the global distribution of urinary proteins, the proteome, differs between women with and those without SUI. METHODS: In this age-matched case-control study, we compared the urinary proteome of 20 women with SUI and 20 controls. Proteins were identified by applying high-performance liquid chromatography separation and tandem mass spectrometry detection. Data analysis was performed using Mascot 2.4.1 embedded in ProteinScape 3.1. RESULTS: We identified 828 different proteins. The concentration of six of those showed a significant difference between urine samples of SUI patients and those of controls (q value < 0.25). Four proteins showed a higher abundance in SUI samples compared with controls: plasma serine protease inhibitor (logFC 1.11), leucine-rich alpha-2-glycoprotein (logFC 3.91), lysosomal alpha-glucosidase (logFC 1.24), and peptidyl-prolyl cis- trans isomerase A (logFC 1.96). We identified two proteins in lower abundance in SUI samples compared with controls: uromodulin (logFC -4.87) and TALPID3 (logFC -1.99). CONCLUSIONS: Overexpression of plasma serine protease inhibitor, leucine-rich alpha-2-glycoprotein, lysosomal alpha-glucosidase, and peptidyl-prolyl cis- trans isomerase A, and lower expression of uromodulin and TALPID3, in urine may be associated with female SUI.

Vibrating vaginal balls to improve pelvic floor muscle performance in women after childbirth: a protocol for a randomised controlled feasibility trial.

AIM: This paper presents a feasibility trial protocol the purpose of which is to prepare for a future randomised controlled trial to determine the effectiveness of vibrating vaginal pelvic floor training balls for postpartum pelvic floor muscle rehabilitation. BACKGROUND: Vibrating vaginal pelvic floor training balls are available in Austria to enhance women's pelvic floor muscles and thus prevent or treat urinary incontinence and other pelvic floor problems following childbirth. Nonetheless, there is currently little empirical knowledge to substantiate their use or assess their relative effectiveness in comparison to current standard care, which involves pelvic floor muscle exercises. DESIGN: Single blind, randomised controlled feasibility trial with two parallel groups. METHODS: It is planned to recruit 56 postpartum women in Vienna, who will be randomised into one of two intervention groups to use either vibrating vaginal balls or a comparator pelvic floor muscle exercises for 12 weeks. As this is a feasibility study, study design features (recruitment, selection, randomisation, intervention concordance, data collection methods and tools) will be assessed and participants' views and experiences will be surveyed. Tested outcome measures, collected before and after the intervention, will be pelvic floor muscle performance as reported by participants and measured by perineometry. Descriptive and inferential statistics and content analysis will serve the preparation of the future trial. DISCUSSION: The results of this feasibility trial will inform the design and conduct of a full randomised controlled trial and provide insight into the experiences of women regarding the interventions and study participation.

Disclosures, conflict of interest, and funding issues in urogynecology articles: a bibliometric study.

INTRODUCTION AND HYPOTHESIS: The ethical behavior of authors, editors, and journals is increasingly placed in the spotlight, by both the public and the research community. Disclosures and conflict of interest (COI) statements of publishing authors represent one important aspect. We aimed to unravel the current management of disclosures, COI, and funding statements in the subspecialty urogynecology. METHODS: A bibliometric study was carried out. We included six journals that published urogynecology articles between January and December 2013. All original articles, reviews, and opinion articles were assessed for the presence of disclosure/COI and funding statements. Information given on the official disclosure form was compared with information given in the final article (International Urogynecology Journal). RESULTS: All journals investigated require disclosure and funding statements in their instructions to authors. Of the 434 articles included, almost all contained a disclosure statement (98-100 %). Funding statements were present in 41-100 % of articles, indicating a difference in journal type (50 % on average among urogynecology journals; 75 % on average among general gynecology journals). The main source of funding was "grants" (58 %), followed by "none" (16 %), "industry" (16 %), and lastly "hospital/university" (10 %). Disclosure statements in the article were identical to the official disclosure form in 80 % (IUJ). CONCLUSIONS: Disclosure/COI statements were included in almost all urogynecology articles investigated. Their content, however, is sometimes incomplete and should possibly be monitored more closely by journals and authors. Despite universal requirements of journals, the reporting of funding seems inconsistent. This issue in addition to the completeness of disclosures should be given more attention.

Retropubic vs. transobturator tension-free vaginal tape for female stress urinary incontinence: 3-month results of a randomized controlled trial.

BACKGROUND: We conducted a prospective randomized controlled noninferiority trial to compare objective and subjective outcomes of retropubic tension-free vaginal tape (TVT) with those of transobturator tape (TVT-O) as primary treatment for stress urinary incontinence (SUI) in women. STUDY DESIGN: The study was conducted at 25 gynecology units in Austria and Germany; regional and academic hospitals participated. A total of 569 patients were randomly assigned to undergo TVT or TVT-O. RESULTS: A total of 480 patients (85%) were examined at 3 months. A negative cough stress test with stable cystometry to 300 ml was seen in 87% of patients after TVT and in 84% after TVT-O; 64% and 59% of patients, respectively, reported no pad use, and 88% of patients in both groups considered themselves much or very much better on the Patient Global Impression of Improvement (PGI-I) scale. Quality of life (QoL) as assessed with the SF-12 Health Survey, Kings' Health Questionnaire, (KHQ), and EuroQol-5D (EQ-5D) was significantly improved in both arms, with no differences between arms. There were no significant differences in postoperative pain or complications. CONCLUSIONS: Results of this trial demonstrate noninferiority between TVT and TVT-O with regard to postoperative continence and QoL and suggest little difference in perioperative problems (ClinicalTrials.gov NCT 00441454).

Management of Third and Fourth-Degree Perineal Tears After Vaginal Birth. Guideline of the DGGG, OEGGG and SGGG (S2k-Level, AWMF Registry No. 015/079, December 2020).

Purpose This guideline provides recommendations for the diagnosis, treatment and follow-up care of 3rd and 4th degree perineal tears which occur during vaginal birth. The aim is to improve the management of 3rd and 4th degree perineal tears and reduce the immediate and long-term damage. The guideline is intended for midwives, obstetricians and physicians involved in caring for high-grade perineal tears. Methods A selective search of the literature was carried out. Consensus about the recommendations and statements was achieved as part of a structured process during a consensus conference with neutral moderation. Recommendations After every vaginal birth, a careful inspection and/or palpation by the obstetrician and/or the midwife must be carried out to exclude a 3rd or 4th degree perineal tear. Vaginal and anorectal palpation is essential to assess the extent of birth trauma. The surgical team must also include a specialist physician with the appropriate expertise (preferably an obstetrician or a gynecologist or a specialist for coloproctology) who must be on call. In exceptional cases, treatment may also be delayed for up to 12 hours postpartum to ensure that a specialist is available to treat the individual layers affected by trauma. As neither the end-to-end technique nor the overlapping technique have been found to offer better results for the management of tears of the external anal sphincter, the surgeon must use the method with which he/she is most familiar. Creation of a bowel stoma during primary management of a perineal tear is not indicated. Daily cleaning of the area under running water is recommended, particularly after bowel movements. Cleaning may be carried out either by rinsing or alternate cold and warm water douches. Therapy should also include the postoperative use of laxatives over a period of at least 2 weeks. The patient must be informed about the impact of the injury on subsequent births as well as the possibility of anal incontinence.

Relaxin and gonadal steroid receptors in uterosacral ligaments of women with and without pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: This study evaluates the expression of estrogen receptor isoforms alpha (ERα) and beta (ERß), progesterone receptor (PR), and relaxin receptor isoforms 1 and 2 (LGR7, LGR8) in uterosacral ligament (USL) tissue of women with pelvic organ prolapse and controls. METHODS: Tissue samples of USL from women with and without pelvic organ prolapse (POP) were subjected to immunohistochemistry against ERα, ERß, PR, and LGR7 proteins. The respective mRNA expression as well as of LGR8 was assessed by quantitative real-time polymerase chain reaction. RESULTS: The cellular distribution of the receptor proteins was different due to cell types, independent of POP: ERα and PR were found in smooth muscle cells, but not in endothelial cells, whereas ERß was found in endothelial cells, but not in connective tissue. ERα, ERß, PR, and LGR7 mRNAs could be detected in all patients of both groups. ERα mRNA expression was significantly and ERß mRNA borderline significantly higher in USL of patients with POP: ERα: p < 0.001, ERß: p = 0.057. CONCLUSIONS: Enhanced effects of estrogen via altered mRNA expression patterns of ERα and ERß--but not those of progesterone--may exist in USL of patients affected by POP. A local effect of relaxin needs to be further clarified because of this first report of prevalent ligamental expression of LGR7.

Characteristics of the Urinary Proteome in Women with Overactive Bladder Syndrome: A Case-Control Study.

Despite an estimated prevalence of 13% in women, the exact etiology of non-neurogenic overactive bladder syndrome is unclear. The aim of our study was to gain a better understanding of the pathophysiology of female overactive bladder syndrome by mapping the urinary proteomic profile. We collected urine samples of 20 patients with overactive bladder syndrome and of 20 controls. We used mass spectrometric analysis for label-free quantitation, Swissprot human database for data search, Scaffold for data allocation and the Reactome Knowledgebase for final pathway enrichment analysis. We identified 1897 proteins at a false discovery rate of 1% and significance level p < 0.001. Thirty-seven significant proteins of the case group and 53 of the control group met the criteria for further pathway analysis (p < 0.0003 and Log2 (fold change) >2). Significant proteins of the overactive bladder group were, according to the 25 most relevant pathways, mainly involved in cellular response to stress and apoptosis. In the control group, significant pathways mainly concerned immunological, microbial-protective processes and tissue- elasticity processes. These findings may suggest a loss of protective factors as well as increased cellular response to stress and apoptosis in overactive bladder syndrome.

Transobturator tapes for stress urinary incontinence: Results of the Austrian registry.

OBJECTIVE: We established a voluntary registry to collect data on the perioperative course of transobturator tape operations for stress incontinence. STUDY DESIGN: Forty-seven centers completed a 1-page, 15-item questionnaire per procedure. RESULTS: Data on a total of 2543 operations with 11 different tape systems were collected. Intraoperative complications were noted for 120 procedures (4.7%). These included 85 cases of increased bleeding (3.3%), 10 vaginal perforations (0.4%), 10 bladder perforations (0.4%), and 2 urethral perforations. Reoperations attributable to the tape procedure were reported for 57 patients (24 tapes cut or loosened for voiding dysfunction, 11 vaginal erosions, 7 abscesses with erosions). One patient was reoperated at 14 days for a retropubic hematoma. There were no reports of bowel or major vessel injuries or mortality. Significant postoperative pain was reported for 12 patients (0.5%), although this was not specifically asked for in the questionnaire. CONCLUSION: Significant complications with transobturator tapes are uncommon. Bladder perforations occurred more frequently with outside-in than with inside-out techniques. Vaginal erosions, abscesses, and pain may be more common with transobturator than with retropubic tapes, and this may be due to the structure of the tapes rather than to the route of passage.

Management of vesicovaginal fistulas (VVFs) in women following benign gynaecologic surgery: A systematic review and meta-analysis.

BACKGROUND: Vesicovaginal fistulas (VVF) are the most commonly acquired fistulas of the urinary tract, but we lack a standardized algorithm for their management. Surgery is the most commonly preferred approach to treat women with primary VVF following benign gynaecologic surgery. OBJECTIVE: To carry out a systematic review and meta-analysis on the effectiveness of operative techniques or conservative treatment for patients with postsurgical VVF. Our secondary objective was to define the surgical time and determine the types of study designs. METHODS: PubMed, Old Medline, Embase and Cochrane Central Register of Controlled Trials were used as data sources. This systematic review was modelled on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, including a registration number (CRD42012002097). RESULTS: We reviewed 282 full text articles to identify 124 studies for inclusion. In all, 1379/1430 (96.4%) patients were treated surgically. Overall, the transvaginal approach was performed in the majority of patients (39%), followed by a transabdominal/transvesical route (36%), a laparoscopic/robotic approach (15%) and a combined transabdominal-transvaginal approach in 3% of cases. Success rate of conservative treatment was 92.86% (95%CI: 79.54-99.89), 97.98% in surgical cases (95% CI: 96.13-99.29) and 91.63% (95% CI: 87.68-97.03) in patients with prolonged catheter drainage followed by surgery. 79/124 studies (63.7%) provided information for the length of follow-up, but showed a poor reporting standard regarding prognosis. Complications were studied only selectively. Due to the inconsistency of these data it was impossible to analyse them collectively. CONCLUSIONS: Although the literature is imprecise and inconsistent, existing studies indicate that operation, mainly through a transvaginal approach, is the most commonly preferred treatment strategy in females with postsurgical VVF. Our data showed no clear odds-on favorite regarding disease management as well as surgical approach and current evidence on the surgical management of VVF does not allow any accurate estimation of success and complication rates. Standardisation of the terminology is required so that VVF can be managed with a proper surgical treatment algorithm based on characteristics of the fistula.

Proteomic Pattern in Overactive Bladder Including Gender Aspects: A Case-control Study.

This is a clinical trial update without results. The aim of the trial is to identify a urinary proteomic pattern, including gender aspects, for patients with overactive bladder syndrome in comparison to healthy controls.

Bleeding complications with the tension-free vaginal tape operation.

OBJECTIVE: This study was undertaken to analyze bleeding problems with tension-free vaginal tape (TVT) operations in a national registry. STUDY DESIGN: We studied patients for whom increased intraoperative bleeding or reoperation for bleeding/hematoma with TVT operation were reported to the registry. RESULTS: Bleeding problems were reported for 151 of 5578 (2.7%) TVT operations. Increased intraoperative bleeding was reported for 106 (1.9%) and reoperation (or conversion) in 45 (0.8%) patients (both in 5 patients). Increased intraoperative bleeding was managed conservatively in 103 patients (95%). Overall, 45 (0.8%) patients required reintervention for bleeding or hematoma. The reinterventions comprised 34 laparotomies, 4 transvaginal evacuations of hematomas, 3 revisions for bleeding from a suprapubic catheter site, and 2 revisions of the vaginal incision (details unclear in 1 patient). Bleeding was considered arterial in 12% (including 1 external iliac artery injury and 1 obturator artery injury) and venous or unknown in 88%. Of reoperated patients, 39% were reoperated within 24 hours, 20% within 2 to 10 days, and 41% within 11 to 56 days after TVT placement. Overall, 19 patients received blood transfusions (range, 1-10 units). There were no deaths from bleeding complications. CONCLUSION: Bleeding complications were reported with less than 3% of 5578 TVT operations. Most cases of increased intraoperative bleeding were managed conservatively; 0.8% of patients required conversion or reoperation.

Percutaneous tibial nerve stimulation versus tolterodine for overactive bladder in women: a randomised controlled trial.

OBJECTIVE: We performed a randomised controlled trial of percutaneous tibial nerve stimulation (PTNS) versus tolterodine for treating treatment naïve women with overactive bladder (OAB). STUDY DESIGN: 36 patients with symptoms of OAB were randomised to 3 months of treatment with weekly PTNS or tolterodine (2mg bid p.o.). The primary outcome measure was the difference of micturitions per 24h. The secondary outcome measure was the impact on quality of life (QoL) measured with a visual analogue scale (VAS) between baseline and after 3 months of therapy. RESULTS: Micturition frequencies did not decline significantly (p=0.13) over time and there were no significant treatment differences (p=0.96). QoL was significantly dependent from its level at baseline (p=0.002) and showed improvement over time compared to baseline measurements but no significant differences between both treatment groups (p=0.07). Incontinence episodes per 24h depended significantly on the level at baseline (p=0.0001) and declined significantly (p=0.03) during 3 months of therapy in both therapy groups. However no significant treatment differences on the reduction of incontinence episodes in 24h could be shown between both therapy groups (p=0.89). PTNS had fewer side effects than tolterodine (p=0.04). CONCLUSION: PTNS and tolterodine were both effective in reducing incontinence episodes and improving QoL in patients with OAB but not micturition frequencies. PTNS had fewer side effects.

The urethra during pelvic floor contraction: observations on three-dimensional ultrasound.

OBJECTIVE: To investigate with three-dimensional ultrasound how voluntary pelvic floor contractions influence the morphology of the female urethra's components. METHODS: Twenty female patients with benign gynecologic disorders (mean age: 29 years; range: 19-40) had transrectal sonography using a 7.5-MHz mechanical sector endoprobe with three-dimensional features during both pelvic floor muscle relaxation and pelvic floor muscle contraction. The multiplanar display of the scanned volumes allowed detailed morphologic assessment of the urethra and the measurement of distances and volumes of the urethral components. Statistical end points were maximum sagittal and transverse urethral diameter, maximum sphincter length and thickness, maximum smooth muscle thickness, and the volumes of the sphincter, the smooth muscle, and the entire urethra. RESULTS: All 20 rectal scans were feasible. Two patients had to be excluded from analysis because of poor image quality, leaving 18 patients for evaluation. When compared with pelvic floor relaxation, the following measures were smaller during pelvic floor contraction: sagittal urethral diameter (10.4 versus 11.5 mm; P =.004), transverse urethral diameter (14.1 versus 15.0 mm; P =.009), urethral sphincter thickness (2.4 versus 2.7 mm; P =.012), urethral sphincter volume (0.5 versus 0.6 mL; P =.003), and total urethral volumes (1.4 versus 1.5 mL; P =.007). Sphincter length and smooth muscle thickness, as well as smooth muscle volume, did not change significantly during pelvic floor contraction. CONCLUSION: On three-dimensional ultrasound, the morphologic changes of the female urethra during pelvic floor contraction suggest external compression of the urethra rather than contraction of the sphincter muscle.
