EAU guidelines on surgical treatment of urinary incontinence

Midurethral sling position and surgical outcome: A meta-analysis

There is still ongoing debate as to whether the outcome of the sling is determined by the position of the midurethral sling. In order to evaluate the potential impact of sling position on the outcomes of retropubic and transobturator sling procedures for stress urinary incontinence, it is necessary to conduct further investigations. We conducted a comprehensive search across various electronic databases such as PubMed, EMBASE, MEDLINE. Relevant data were extracted, organized in a table format, and analyzed using RevMan software for further analysis. This review comprised a total of 9 studies. The findings indicate that patients with TVT tape placement in the midurethra exhibited a slightly higher cure rate compared to those with proximal placement. Conversely, tape placement in the midurethra was associated with a significantly higher cure rate compared to distal placement [RR = 0.84, 95% CI (0.74-0.95), P < .05]. In the case of transobturator slings, tape positioning beneath the midurethra or distal urethra yielded better outcomes compared to placement near the bladder neck [RR = 0.74, 95% CI (0.57-0.94), P = .02; RR = 0.61, 95% CI (0.39-0.96), P = .03]. Based on 2D and 3D ultrasound imaging, differences in TVT placement appear to have minimal impact on the cure rate. However, the highest rate of failure after transobturator sling surgery is closely linked to the positioning.

Magnetically controlled artificial urinary sphincter: An overview from existing devices to future developments

BACKGROUND

Urinary incontinence is a common clinical problem in the world today. Artificial urinary sphincter is a good treatment approach for severe urinary incontinence, which is designed to mimic the action of the human urinary sphincter and assist patients to regain urinary function.

METHODS

There are many control methods based on artificial urinary sphincter, such as hydraulic control, electromechanical control, magnetic control, and shape memory alloy control. In this paper, the literature was first searched and documented based on PRISMA search strategy for selected specific subject terms. Then, a comparison of artificial urethral sphincters based on different control methods was conducted, and the research progress of magnetically controlled artificial urethral sphincters was reviewed, and their advantages and disadvantages were summarized. Finally, the design factors for the clinical application of magnetically controlled artificial urinary sphincter are discussed.

RESULTS

As magnetic control allows for non-contact force transfer and does not generate heat, it is proposed that magnetic control may be one of the more promising control methods. The design of future magnetically controlled artificial urinary sphincters will need a variety of considerations, including the structural design of the device, manufacturing materials, manufacturing costs, and convenience. In addition, validation of the safety and effectiveness of the device and device management are equally important.

CONCLUSIONS

The design of an ideal magnetically controlled artificial urinary sphincter is of great importance to enhance patient treatment outcomes. However, there are still great challenges to be faced for the clinical application of such devices.

Management of Urinary Incontinence Following Radical Prostatectomy: Challenges and Solutions

Urinary incontinence is a common and debilitating problem in patients undergoing radical prostatectomy. Current methods developed to treat urinary incontinence include conservative treatments, such as lifestyle education, pelvic muscle floor training, pharmacotherapy, and surgical treatments, such as bulking agents use, artificial urinary sphincter implants, retrourethral transobturator slings, and adjustable male sling system. Pelvic floor muscle exercise is the most common management to improve the strength of striated muscles of the pelvic floor to try to recover the sphincter weakness. Antimuscarinic drugs, phosphodiesterase inhibitors, duloxetine, and a-adrenergic drugs have been proposed as medical treatments for urinary incontinence after radical prostatectomy. Development of new surgical techniques, new surgical tools and materials, such as male slings, has provided an improvement of outcomes after UI surgery. Such improvement is still ongoing, and the uptake of new devices might lead to even better outcomes after UI surgery.

Impact of Duration of Antibiotic Prophylaxis on Incidence of UTI after OnabotulinumtoxinA Injection

OBJECTIVE

To assess the impact of duration of antibiotic prophylaxis on incidence of UTI after intravesical OnabotulinumtoxinA (BTX) injection.

METHODS

A retrospective cohort study of patients with overactive bladder (OAB) who underwent office BTX injections from 2014-2020. UTI incidence within 30 days of BTX was compared between three durations of antibiotic prophylaxis: no antibiotic, single day, or multiple day course. Association of UTI with units of BTX, BMI, history of diabetes, immunosuppression, neurogenic OAB, chronic catheter, or recurrent UTI were investigated.

RESULTS

290 patients and 896 cycles of BTX injections were included: 877 injections (97.7%) were women, with mean age 61.4 years (range 20-96; SD 13.3). No antibiotic prophylaxis was given to 112 (12.5%) patients, 595 (66%) received a single day, and 189 (21%) received a multiple day regimen (3-7 days). Overall incidence of UTI within 30 days was 11.4%. On multivariable logistic regression, use of any antibiotic prophylaxis was associated with a lower incidence of UTI (single OR 0.34; 95% CI 0.19-0.61; p<0.001; multiple OR 0.47; 95% CI 0.24-0.92; p=0.029), with no difference between single and multiple day regimens (OR 1.38; 95% CI 0.80-2.38; p=0.249). History of recurrent UTI (OR 3.77; 95% CI 2.23-6.39; p<0.001) and chronic suprapubic catheter (OR 2.88; 95% CI 1.04-7.95; p=0.041) were additional predictors.

CONCLUSION

A multiple day regimen of antibiotic prophylaxis was not more effective than a single day in preventing UTI for intravesical BTX injection. Use of any antibiotic prophylaxis was associated with a significantly lower incidence of UTI compared to no antibiotic.

2021 opinion from the CUROPF on THE efficacy and safety of mid-urethral slings used in women WITH urinary stress incontinence

OBJECTIVE

To determine the usefulness of mid-urethral slings (MUS) in the surgical management of women presenting with urinary stress incontinence (USI) METHOD: A consensus committee of multidisciplinary experts (CUROPF) was convened and focused on PICO questions concerning the efficacy and safety of MUS surgery compared to other procedures and concerning which approach (retropubic (RP) vs transobturator (TO)) should be proposed as a first-line MUS surgery for specific subpopulations (obese; intrinsic sphincteric deficiency (ISD); elderly) RESULTS: As compared to other procedures (urethral bulking agents, traditional slings and open colposuspension), the MUS procedure should be proposed as the first-line surgical therapy (strong agreement). MUS surgery can be associated with complications and proper pre-operative informed consent is mandatory (strong agreement). Mini-slings (SIS/SIMS) should only be proposed in clinical trials (strong agreement). Both RP and TO approaches may be proposed for the insertion of MUS (strong agreement). However, if the woman is willing to accept a moderate increase in per-operative risk, the RP approach should be preferred (strong agreement) since it is associated with higher very long-term cure rates and as it is possible to completely remove the sling surgically if a severe complication occurs. The RP approach should be used for the insertion of MUS in a woman presenting with ISD (strong agreement). Either the RP or TO approach should be used for the insertion of MUS in an obese woman presenting with USI (strong agreement). In very obese women (BMI ≥35-40kg/m²), weight loss should be preferred prior to MUS surgery and bariatric surgery should be discussed (strong agreement) CONCLUSION: The current Opinion provides an appropriate strategy for both the selection of patients and the best therapeutic approach in women presenting with USI.

New technique of robot-assisted laparoscopic artificial urinary sphincter implantation in female by a posterior approach with intraoperative cystoscopic monitoring

PURPOSE

To report the early experience of a modified technique of robot-assisted artificial urinary sphincter (AUS) implantation in female, with a posterior approach to the bladder neck and intraoperative real-time cystoscopic monitoring.

METHODS

Retrospective monocentric study included all consecutive female who underwent a primary robot-assisted AUS implantation between 2017 and 2019. Real-time intraoperative cystoscopic monitoring was carried out to check the correct level of the dissection and to avoid any injury during bladder neck dissection. Perioperative and intraoperative data, functional outcomes and complications were assessed. Continence was defined as 0 to 1 pad per day.

RESULTS

Twenty-four patients were included, the median age was 66 years, 23/24 (96%) had previous SUI or prolapse surgery. Two conversions to open surgery and 2 modifications of the surgical technique with anterior dissection of the bladder neck were required due to major vesicovaginal adhesions. Overall, 20 patients underwent the robotic posterior approach. Eleven intraoperative complications in 10 patients (50%) occurred, including 7 bladder injuries 4 vaginal injuries, without the need to stop the procedure. The median hospital stay was 3 days (2-7). One AUS was removed at 1 year due to vaginal erosion. At last follow-up (median 26 months (22-36)), 95% of the devices were in place and activated and the continence rate was 84%.

CONCLUSIONS

Early functional results of robot-assisted AUS implantation with a posterior approach to the bladder neck and intraoperative cystoscopic monitoring are promising despite the high rate of intraoperative complications due to previous surgeries. Further evaluation of this technique is required.

Long-term functional outcomes of artificial urinary sphincter (AMS 800™) implantation in women aged over 75 years and suffering from stress urinary incontinence caused by intrinsic sphincter deficiency

PURPOSE

To assess the outcomes after artificial urinary sphincter (AUS) implantation in older women aged over 75 years.

METHODS

A monocentric retrospective study included all non-neurological women aged over 75 years suffering from stress urinary incontinence (SUI) due to intrinsic sphincter deficiency and undergoing an AUS placement between 1991 and 2015. Early postoperative complications were reported according to Clavien-Dindo classification. Continence, defined as no pad use, was assessed at the end of follow-up. Explantation, revision and deactivation rates of the AUS were reported. A Kaplan-Meier survival curve was generated to evaluate the survival rate of the device without revision or explantation.

RESULTS

Among 393 AUS implantations, a total of 45 patients, median age 77 years (IQR 75-79), were included. Twenty-six early postoperative complications occurred in 18 patients (40%) patients. All were minor Clavien grades (I-II) except one (grade IVa). Median follow-up was 36 months (IQR 16-96). Overall, 32 women (71.1%) still had their AUS in place at the end of the follow-up, without revision or explantation. The AUS was definitively removed in four (8.9%). The AUS required revisions in nine (20%) women. The 5- and 10-year survival rates of the device without revision or explantation were 78 and 50%, respectively. Three patients (6.7%) had their AUS deactivated. At last follow-up, in an intention-to-treat analysis, the continence rate was 68.9%.

CONCLUSION

In women aged over 75-years-old, suffering from SUI, the AUS provides satisfactory functional results comparable to the general population.

Treatment of urinary incontinence: a critical appraisal of clinical practice guidelines with the AGREE II instrument

INTRODUCTION AND HYPOTHESIS

This systematic review evaluated the rigor of the development of clinical practice guidelines (CPG).

METHODS

The searched sources were MEDLINE, EMBASE, Web of Science, Scopus, and specific databases of CPG. Reviewers, organized in triplicate and independently, selected the studies and assessed the quality of the guidelines using the Appraisal of Guidelines Research and Evaluation (AGREE II) instrument, which contains six domains for classification. The classification of the CPGs prioritized the domain 3 (developmental rigor) considering: high (score > 60%), moderate (score 30-60%), or low quality (score < 30%). The results were checked for discrepancies and decided by consensus. The interventions were described. Descriptive statistics presented the results.

RESULTS

Of the ten CPGs evaluated, five were of high methodological quality, three were of moderate quality, and two of low quality. Three documents were not recommended for use. The domains with the highest scores were scope and purpose (mean = 90.1%) and clarity of presentation (mean = 88.9%). The domains of editorial independence (mean = 41.4%) and applicability (mean = 29.3%) were those with the lowest score. The most cited interventions in CPGs were the nonpharmacological, such as lifestyle interventions, bladder training, or re-education and pelvic floor muscle training.

CONCLUSION

Most guidelines showed rigor in development and were recommended for use; however, editorial independence and applicability were domains that need to be improved in these documents. Our findings can guide the choice of CPG for the treatment of urinary incontinence.

Standing cough test stratification of moderate male stress urinary incontinence

PURPOSE

Patient-reported history of pads per day (PPD) is widely recognized as a fundamental element of decision-making for anti-incontinence procedures. We hypothesize that SUI severity is often underestimated among men with moderate SUI. We sought to compare patient history of incontinence severity versus objective in-office physical examination findings.

MATERIALS AND METHODS

We retrospectively reviewed our single-surgeon male SUI surgical database from 2007-2019. We excluded patients with incomplete preoperative or postoperative data and those who reported either mild or severe SUI, thus having more straightforward surgical counseling. For men reported to have moderate SUI, we determined the frequency of upgrading SUI severity by recording the results of an in-office standing cough test (SCT) using the Male Stress Incontinence Grading Scale (MSIGS). The correlation of MSIGS with sling success rate was calculated. Failure was defined as >1 PPD usage or need for additional incontinence procedure.

RESULTS

Among 233 patients with reported moderate SUI (2-3 PPD), 89 (38%) had MSIGS 3-4 on SCT, indicating severe SUI. Among patients with 2-3 PPD preoperatively, sling success rates were significantly higher for patients with MSIGS 0-2 (76/116, 64%) compared to MSIGS 3-4 (6/18, 33%) (p <0.01).

CONCLUSIONS

Many men with self-reported history of moderate SUI actually present severe SUI observed on SCT. The SCT is a useful tool to stratify moderate SUI patients to more accurately predict sling success.

Five-Year Results of a Prospective Multicenter Trial: AdVance XP for Postprostatectomy-Incontinence in Patients with Favorable Prognostic Factors

OBJECTIVE

The aim of this study was to assess the security, value, and efficacy of the second-generation AdVance male sling XP (Boston Scientific®), after implementation in 2010 with advantageous modifications in the sling structure and needle shape, in a prospective multicenter long-term follow-up study.

METHODS

In total, 115 patients were included. Exclusion criteria were earlier incontinence (UI) surgery, nocturnal UI, former radiotherapy, or night-time incontinence. We also excluded patients with a functional urethra <1 cm in a preoperatively performed repositioning test. A consistent 24-h pad test, International Quality of Life (IQOL) score, visual analog pain scale (VAS), International Consultation-Incontinence Questionnaire (ICIQ-UI SF), International Index of Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS), and Patient Global Impression of Improvement (PGI-I) scores were requested postoperatively.

RESULTS

The 24-month follow-up (114 patients) revealed 64.0% cured and 28.8% improved patients. Mean urine loss was reduced significantly to 19.0 g (p < 0.001). A mean PGI score of 1.5 and a mean VAS score of 0.2 were obtained. The 60-month follow-up (59 patients) revealed 57.6% cured and 25.4% improved patients. Mean urine loss was reduced significantly to 18.3 g (p < 0.001). A mean PGI score of 1.6 and a mean VAS score of 0.2 were obtained.

CONCLUSIONS

The AdVance XP displays excellent continence results and secure effectiveness over a 5-year period. Moreover, these data are demonstrating low complication rates and improved quality of life in the long-term use of AdVance XP.

Embryology of the urogenital tract; a practical overview for urogynecologic surgeons

INTRODUCTION AND HYPOTHESIS

Urinary tract anomalies are one of the most common birth defects. Nevertheless, they prove challenging to diagnose as a result of variable presenting symptoms. We aimed to perform a review of urogenital tract development, highlight common congenital upper urinary tract anomalies encountered by urogynecologists and tools to facilitate diagnosis.

METHODS

Multiple searches were performed utilizing resources such as PubMed and the TriHealth library database to access publications related to embryology of the urinary tract and urinary tract anomalies. Each citation was reviewed.

RESULTS

Congenital urinary tract anomalies account for up to 20% of all birth defects and occur more often in females. The true incidence of these malformations is unknown as some can remain clinically insignificant throughout life. In addition, patients may present with non-specific complaints such as urinary tract infections, nephrolithiasis or urinary incontinence. Therefore, unsuspected anomalies pose a risk of delayed diagnosis and potential injury during urogynecologic surgery. Imaging modalities such as computed tomography or magnetic resonance imaging are the most common diagnostic tests. Management and treatment options range from observation to surgical resection with the goal of optimizing long-term functionality and prevention of chronic sequelae.

CONCLUSION

Patients with urinary tract anomalies can present with vague complaints often encountered by urogynecologists. It is crucial to understand the embryologic development of urinary tract anomalies to help facilitate diagnosis and guide care within the office and operating room setting.

Current Overview of Surgical Options for Female Stress Urinary Incontinence

Stress urinary incontinence (SUI) is a highly prevalent health condition that significantly impacts the quality of life. Traditional methods of treatment for SUI, such as pubovaginal sling and Burch colposuspension, have been replaced by the midurethral sling because of its high efficacy, low complication and morbidity rates, and short learning curve. Although multiple behavioral and operative treatments exist, midurethral slings are the gold standard for the treatment of SUI in women. However, several reports have raised concerns about complications caused by the synthetic mesh used in midurethral slings. Therefore, surgical treatment for SUI in women must be chosen with care, taking into account potential complications. Herein, we review the current safety issues pertaining to the use of meshes, the efficacy of traditional surgeries, old and new midurethral slings, and recent data comparing the efficacy and safety of different surgical options. This review is aimed at developing practical guidelines for choosing surgical options for women with SUI.

Contasure-needleless single incision slings versus transobturator slings (TOT/TVT-O) for female patients with stress urinary incontinence: a systematic review and meta-analysis

Background

To assess the current evidence on the effectiveness and safety of Contasure-Needleless (C-NDL) versus transobturator slings (TOT/TVT-O) in the management of female stress urinary incontinence (SUI).

Methods

A comprehensive literature review of articles that investigated the efficacy and safety of C-NDL and TOT/TVT-O was performed based on studies published before June 2019 and retrieved from PubMed, Embase, CNKI and the Cochrane Library. Two reviewers searched the literature, independently extracted the data and evaluated the quality of the data according to the inclusion and exclusion criteria. A meta-analysis was performed by using Review Manager 5.3 software.

Results

Seven studies with 1188 SUI female patients without intrinsic sphincter deficiency (ISD) or mixed urinary incontinence were included. Our meta-analysis showed that the clinical efficacy of C-NDL is statistically non-inferior to that of TOT / TVT-O in terms of subjective cure rate [OR = 0.77, 95% confidence interval (CI) (0.53 to 1.10), p = 0.15] and objective cure rate [OR = 0.78, 95% CI (0.53 to 1.13), p = 0.19]. In addition, operating times were statistically shorter with C-NDL compared to TOT / TVT-O [mean difference (MD) = − 7.38, 95% CI (− 10.73 to − 4.04), p < 0.0001]. In terms of the postoperative visual analogue scale (VAS) and the incidence of postoperative pain, C-NDL has a greater advantage [MD = − 1.71, 95% CI (− 2.91 to − 0.50), p = 0.005]; [OR = 0.21, 95% CI (0.05 to 0.96), p = 0.04]. Complication rates were statistically similar between the groups, except for groin pain which was higher in TOT / TVT-O.

Conclusion

Our data suggest that C-NDL slings have similar short-term efficacy as TOT/TVT-O in curing SUI patients. Compared with TOT/TVT-O, C-NDL is associated with a shorter operative time, and the incidence of postoperative pain is decreased. Nevertheless, these findings should be further confirmed through large-volume, well-designed prospective randomized controlled trials (RCTs) with long-term follow-up.

The current state and the future of robotic surgery in female pelvic medicine and reconstructive surgery

In this article, we review the current uses and future directions of robotic surgery in the field of female pelvic medicine and reconstructive surgery. Pelvic surgery is ideal for the use of surgical robots, which provide improved visualization and ease of suturing deep within the pelvis. Robots have been successfully used for the treatment of pelvic organ prolapse, in procedures such as sacrocolpopexy, sacrohysteropexy, and uterosacral ligament plication. Surgeons have used the robotic successfully to treat various etiologies of female pelvic pain including fibroids, endometriosis, and nerve entrapment. Robotic repair of iatrogenic injury has been described with excellent outcomes and avoidance of conversion to open surgery in the event of an injury caused using the robotic platform. While more data is needed on this topic, there has been increasing interest in using the robot for urologic reconstruction including repair of vesico-vaginal fistula, cystectomy, augmentation cystoplasty, and continent and non-continent diversions. Recently the use of the robot has been described in the treatment of stress urinary incontinence in females, with robotic placement of an artificial urinary sphincter. While robotic surgery is associated with increased cost, the outcomes of robotic surgery in female urology are promising. More studies that properly evaluate the benefits of robotic surgery as compared to open and laparoscopic approaches are needed.

Critical appraisal of clinical practice guidelines for treatment of urinary incontinence: Protocol for a systematic review

BACKGROUND

Urinary incontinence is a common complaint in all parts of the world, cause of distress, as well as significant costs for both individuals and society. The aim of this study will be to evaluate the rigor of the development of clinical practice guidelines and to identify the recommendations of interventions for urinary incontinence in adult women.

METHODS

In this systematic review, clinical practice guidelines will be identified using a prospective protocol through a systematic search of: MEDLINE (via Ovid); EMBASE (Excerpt Medical Database, via Ovid); Web of Science and Virtual Health Library. Specific databases of guidelines for clinical practice will also be searched (National Institute for Health and Care Excellence, American Urological Association, and others). Reviewers, independently and in duplicate, will assess the quality of the guidelines using the Appraisal of Guidelines Research and Evaluation (AGREE II). The results will be checked for discrepancies. Differences between the scores equal to or greater than 2 will be considered as discrepant and the final result will be decided by consensus. A comparison of the recommendations of interventions and information about the level of evidence, the degree of recommendation, the level of agreement and the level of acceptance will be described. This step will also be done independently and in duplicate, and the result will be decided by consensus. The results will be presented in tables and the descriptive statistics will be calculated for all domains of the AGREE II instrument as mean (standard deviation) and median (interquartile range).

RESULTS

The results derived from this study will increase the knowledge about the development of recommendations guidelines for urinary incontinence of high methodological rigor. This study may also identify key areas for future research.

CONCLUSION

This study may guide health professionals, policy makers, and health policy managers in choosing the guidelines for recommendation in clinical practice.

Surgical treatment of post-prostatectomy stress urinary incontinence in adult men: Report from the 6th International Consultation on Incontinence

AIMS

To report the recommendations of the 6th International Consultation on Incontinence (ICI) on post-prostatectomy urinary incontinence.

METHODS

The 6th ICI committee on surgical treatment of urinary incontinence in men assessed and reviewed the outcomes of surgical therapy and updated the prior recommendations published in 2013. Articles from peer-reviewed journals, abstracts from scientific meetings, and literature searches by hand and electronically formed the basis of this review. The resulting guidelines were presented at the 2016 ICI meeting in Tokyo, Japan.

RESULTS

Voiding diary and pad tests are valuable for assessing quantity of leakage. Cystoscopy and/or urodynamics may be useful in guiding therapy depending on the type of incontinence and presumed etiology. Artificial Urinary Sphincter (AUS) is the preferred treatment for men with moderate to severe stress urinary incontinence (SUI) after RP. Male slings are an acceptable approach for men with mild to moderate SUI. Much discussion centers on the definition of moderate SUI. Injectable agents have a poor success rate in men with SUI. Options for recurrent SUI due to urethral atrophy after AUS implantation include changing the pressure balloon, downsizing the cuff and increasing the amount of fluid in the system. Infection and/or erosion demand surgical removal or revision of all or part of the prosthesis.

CONCLUSIONS

Although there are several series reporting the outcomes of different surgical interventions for PPUI, there is still a need for prospective randomized clinical trials. Recommendations for future research include standardized workup and outcome measures, and complete reporting of adverse events at long-term.

Modifications to Botulinum toxin A delivery in the management of detrusor overactivity recalcitrant to initial injections: a review

PURPOSE

One quarter of patients will not respond to initial intra-detrusor Botulinum toxin A (BTX) injections for detrusor overactivity. Alternative treatment options include long-term catheterization, sacral neuromodulation, urinary diversion or bladder augmentation. Some of these procedures are invasive. This review explores modifications to BTX delivery that can improve outcome.

METHODS

A search of Medline, Embase and Cochrane Library to December 2017 was performed according to Preferred Reporting Items for Systematic Review and Metaanalysis (PRISMA) guidelines. Search criteria included, dose escalation, increasing injection site number, trigone injection, switching preparation and alternative methods of BTX delivery.

RESULTS

Several modifications to BTX delivery may improve response. There is moderate evidence that increasing the dose from 100 U to 200 U results in statistically better symptom control. Trigone-including injections were associated with significantly improved patient-reported symptom scores, as well as superior results in urodynamic outcomes without risking urinary retention and vesico-ureteric reflux. Switching from onabotulinum (OTA) or abobotulinum (ATA) or vice versa may also improve response in over 50% of patients as shown in limited studies. Increasing the number of injection sites is not beneficial. Indeed, decreasing the number of injections to as low as three sites does not result in decreased clinical outcomes. Injection-free delivery is associated with lower efficacy compared to conventional intradetrusor injections.

CONCLUSION

Before contemplating alternative treatments, practitioners can try to improve on BTX delivery. Firstly, the dose can be increased to 200 U; the trigone included in the injection sites and switching brands may also be helpful.

Retrospective study on the management and follow-up of 18 patients with a mid-urethral sling penetrating the urethra or bladder

INTRODUCTION

The mid-urethral sling (MUS) procedure is the gold-standard for the surgical treatment of stress urinary incontinence (SUI). Urethro-vesical sling exposure is one of the most serious complications of this procedure. We describe the treatment and follow-up of 18 patients with bladder or urethral sling exposure.

PATIENTS AND METHODS

This single-center, retrospective study assessed the diagnosis and management of MUS penetrating the lower urinary tract in 18 women. The lesions included were classed as 4B, T3-4, S3 according to the international classification of complications related to the insertion of prostheses. Diagnosis was confirmed by flexible urethro-cystoscopy. The patients were treated surgically. In all cases, the aim was to remove all synthetic materials eroding the bladder or urethra. The patients were reassessed 6 weeks after the procedure, and functional urologic sequelae were treated. Urologic symptoms were evaluated using the USP questionnaire and urologic comfort was assessed using the Contilife questionnaire.

RESULTS

Seven MUSs were retro-pubic and 11 were trans-obturators. The material was 11 polypropylene macroporous monofilament, four polypropylene silicone coated and three non-available. There were six cases of urethral sling exposure, nine cases of bladder sling exposure, and three cases of urethral and bladder sling exposure, including five complicated cases of lithiasis and one urethra-vaginal fistula. Thirteen patients underwent one surgical procedure, four underwent two, and one underwent five procedures. Seven patients received a Martius flap. Three surgical approaches were necessary: (i) vaginal approach; (ii) urologic (urethral and suprapubic) cystoscopy approach; and (iii) laparoscopy approach. Median follow-up time was 34.5 months. At the end of follow-up, 17/18 patients had no sling exposure from the MUS, and 12/13 patients were considered comfortable from a functional urologic viewpoint.

CONCLUSION

Our study showed that surgery could treat urethro-vesical sling exposure. Three surgical approaches may be necessary. Controlled cystoscopy is vital to confirm healing due to the recurrences of sling exposure in our study.

Refined nomogram incorporating standing cough test improves prediction of male transobturator sling success

AIMS

To develop a decision aid in predicting sling success, incorporating the Male Stress Incontinence Grading Scale (MSIGS) into existing treatment algorithms.

METHODS

We reviewed men undergoing first-time transobturator sling for stress urinary incontinence (SUI) from 2007 to 2016 at our institution. Patient demographics, reported pads per day (PPD), and Standing Cough Test (SCT) results graded 0-4, according to MSIGS, were assessed. Treatment failure was defined as subsequent need for >1 PPD or further procedures. Parameters associated with failure were included in multivariable logistic models, compared by area under the receiver-operating characteristic curves. A nomogram was generated from the model with greatest AUC and internally validated.

RESULTS

Overall 203 men (median age 67 years, IQR 63-72) were evaluated with median follow-up of 45 months (IQR 11-75 months). A total of 185 men (91%) were status-post radical prostatectomy and 29 (14%) had pelvic radiation history. Median PPD and SCT grade were both two. Eighty men (39%) failed treatment (use of ≥1 PPD or subsequent anti-incontinence procedures) at a median of 9 months. History of radiation (P = 0.03), increasing MSIGS (P < 0.0001) and increasing preoperative PPD (P < 0.0001) were associated with failure on univariate analysis. In a multivariable model with AUC 0.81, MSIGS, and PPD remained associated (P = 0.002 and <0.0001 respectively, and radiation history P = 0.06), and was superior to models incorporating PPD and radiation alone (AUC 0.77, P = 0.02), PPD alone (AUC 0.76, P = 0.02), and a cutpoint of >2 PPD alone (AUC 0.71, P = 0.0001).

CONCLUSIONS

MSIGS adds prognostic value to PPD in assessing success of transobturator sling for treatment of SUI.

Overactive bladder treatment: application of methylene blue to improve the injection technique of onabotulinum toxin A

OBJECTIVE

The aim of this study was to test the addition of methylene blue (MB) to onabotulinum toxin A (BTX-A) solution in overactive bladder (OAB) treatment, as a means of facilitating observation of the injection site and assessing the distribution of the drug under the bladder mucosa during injection. Pharmacological interactions between BTX-A and MB were also evaluated.

MATERIALS AND METHODS

The study was conducted between December 2014 and April 2016 on 30 patients: six males and 24 females (median age 57.7, range 23-80 years) diagnosed with OAB, who qualified for intravesical BTX-A injection. Each received 100 IU of BTX-A (Botox^®; Allergan), dissolved in 9.5 ml of 0.9% NaCl with the addition of 0.5 ml of MB. Cystoscopy with submucosal injection of the solution was performed systematically, including the bladder triangle. For pharmacological evaluation, quantitative determination of MB was performed on a capillary electrophoresis system with diode array detection.

RESULTS

In the course of 600 injections, the addition of MB facilitated the observation of the procedure; the exact distribution of the solution could not be observed in only 43 injections in seven patients. The range of distribution of the drug varied from 1 to 2.5 cm. Pharmacological evaluation based on visual observations and experiments showed that pharmaceutical interactions do not occur between MB and this commercially available formulation of BTX-A.

CONCLUSIONS

Applying a coloured solution of BTX-A significantly facilitates observation of the procedure and assessment of drug distribution. There are no pharmaceutical interactions between MB and BTX-A.

The Adjustable Transobturator Male System in Stress Urinary Incontinence After Transurethral Resection of the Prostate

OBJECTIVE

To investigate the efficacy and safety of the Adjustable Transobturator Male System (ATOMS) in men with stress urinary incontinence after transurethral resection of the prostate (TURP).

MATERIALS AND METHODS

From a large international prospectively administrated ATOMS register, we identified 49 patients with an ATOMS device as a result of persistent stress urinary incontinence after TURP. For evaluation, the men were divided into standard transurethral resection of the prostate (sTURP) and palliative transurethral resection of the prostate (pTURP) in radiated patients. Baseline and follow-up measurements included continence parameters, urodynamics, quality-of-life surveys (Patient Global Impression-Improvement and International Consultation on Incontinence Questionnaire-Short Form), and pain ratings. The dry rate (0-1 security pad/<10 mL urine loss), the success rate (overall improvement), removals, complications, and treatment failures were recorded. A P value of <.05 was considered statistically significant.

RESULTS

After a median of 34 and 22 months' follow-up and 2-3 adjustments, the sTURP and pTURP cohorts had 58% and 50% dry rates and 90% and 87% success rates. Hence, no improvement was seen in 10% and 13%. The removal rate was higher in pTURP (50% vs 10%, P = .0171) and infection was the most common side effect (50%) observed. Neither intraoperative nor Clavien-Dindo 4 and 5 adverse events were recorded. In sTURP and pTURP, the median daily pad count and the pad test improved significantly (all P <.001), and quality-of-life parameters shifted to a high satisfaction level (P <.001 and P = .001). Urodynamics remained unchanged and postoperative pain was not an issue.

CONCLUSION

The ATOMS device shows promising treatment outcomes in patients after TURP and a similar efficacy as in postprostatectomy incontinence. There is no difference in continence outcome between sTURP and pTURP; however, a higher removal rate was found after pTURP, which may be important for patient counseling.

Stress urinary incontinence in women: Current and emerging therapeutic options

Surgical management of stress urinary incontinence (SUI) is most commonly achieved by midurethral synthetic sling (MUS) insertion as a first-line surgical option. A great deal of research continues to evolve new management strategies to reach an optimal balance of high efficacy and minimal adverse events. This expert opinion review provides a brief and comprehensive discussion of recent advances and ongoing research in the management of SUI, with an emphasis on single-incision mini-slings, vaginal laser treatment, and cell-based therapy. It is based on data obtained from numerous published meta-analyses and original studies identified through literature search. Single-incision mini-slings appear equally effective initially compared with standard MUS (retropubic or transobturator) for the treatment of female SUI; however, this efficacy lacks durability evidence beyond one-year followup. There is a lack of sufficient clinical evidence to currently confirm long-term safety and effectiveness of cell-therapy and non-ablative vaginal laser therapy, besides suggestion of apparent initial safety. There are still significant challenges to overcome before widespread clinical practice of the latter two modalities. Future research should be aimed at identifying groups of patients who might benefit from these minimally invasive therapeutic options.

Uroflowmetric changes, success rate and complications following Tension-free Vaginal Tape Obturator (TVT-O) operation in obese females

OBJECTIVE

The goal of this study was to evaluate the outcome of Tension-free Vaginal Tape Obturator (TVT-O) operation in the treatment of urodynamic stress incontinence (USI) in obese females, with respect to uroflowmetric changes, success rate and postoperative complications.

METHODS

This prospective observational study included 26 patients with USI at the Obstetrics & Gynecology department-Cairo University hospital during the year 2015. The participants had body mass index (BMI)≥30. Patients underwent TVT-O operation. Follow up of the patients was performed by cough test and uroflowmetry after one week, one month, three months and six months. Postoperative complications such as groin pain, sense of incomplete emptying, need to strain to complete micturition and urinary tract infection were recorded. Comparisons between groups were done using Chi square, Phi-Cramer test for categorical variables.

RESULTS

The mean age for the subjects was 43.58±9.01years. The mean BMI was 33.4±2.1. The success rate of TVT-O operation was 21 out of 26 patients (≈81%). Normal maximum flow rate was in 88% of patients at week one and was normal in 100% of patients at months three and six (p=0.101 & 0.101). Postoperative groin pain was the main complaint during the first week after operation and decreased significantly from week one to the 1st month postoperative (84.62% & 65.38%, P=0.041).

CONCLUSION

TVT-O operation showed a high success rate in treatment of USI in obese patients without affecting the voiding function of the bladder as proven by the uroflowmetry. The main postoperative complaint was the groin pain which significantly improved after one month.

Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence

CONTEXT

Surgical nonautologous meshes have been used for several decades to repair abdominal wall herniae. Implantable materials have been adopted for the treatment of female and male stress urinary incontinence (SUI) and female pelvic organ prolapse (POP).

OBJECTIVE

A consensus review of existing data based on published meta-analyses and reviews.

EVIDENCE ACQUISITION

This document summarises the deliberations of a consensus group meeting convened by the European Association of Urology (EAU) and the European Urogynecological Association, to explore the current evidence relating to the use of polypropylene (PP) materials used for the treatment of SUI and POP, with reference to the 2016 EAU guidelines (European Association of Urology 2016), the European Commission's SCENIHR report on the use of surgical meshes (SCENIHR 2015), other available high-quality evidence, guidelines, and national recommendations.

EVIDENCE SYNTHESIS

Current data suggest that the use of nonautologous durable materials in surgery has well-established benefits but significant risks, which are specific to the condition and location they are used for. Various graft-related complications have been described-such as infection, chronic pain including dyspareunia, exposure in the vagina, shrinkage, erosion into other organs of xenografts, synthetic PP tapes (used in SUI), and meshes (used in POP)-which differ from the complications seen with abdominal herniae.

CONCLUSIONS

When considering surgery for SUI, it is essential to evaluate the available options, which may include synthetic midurethral slings (MUSs) using PP tapes, bulking agents, colposuspension, and autologous sling surgery. The use of synthetic MUSs for surgical treatment of SUI in both male and female patients has good efficacy and acceptable morbidity. Synthetic mesh for POP should be used only in complex cases with recurrent prolapse in the same compartment and restricted to those surgeons with appropriate training who are working in multidisciplinary referral centres.

PATIENT SUMMARY

Synthetic slings can be safely used in the surgical treatment of stress incontinence in both male and female patients. Patients need to be aware of the alternative therapy and potential risks and complications of this therapy. Synthetic mesh for treating prolapse should be used only in complex cases with recurrent prolapse in specialist referral centres.

[Adjustable retropubic suburethral sling Remeex® in the treatment of male stress urinary incontinence: One-year results]

OBJECTIVE

To evaluate the efficacy and safety of the adjustable suburethral sling Remeex^® in the treatment of male stress urinary incontinence (SUI).

PATIENTS AND METHODS

Single-center prospective study of patients treated for SUI after radical prostatectomy or transurethral resection of prostate. The severity of incontinence was evaluated by the number of pads used per day. Success rate, complications and number of adjustments were studied.

RESULTS

From February 2011 to May 2015, Remeex^® was implanted in 25 patients. The average preoperative number of pads used per day was 3,8 (±1,8). Sling tension has been adjusted the day after surgery in all patients. Mean follow-up was 31 months (±15). During follow-up, 6 patients did not need any readjustment (24%) and 15 patients (60%) had to be readjusted. One Remeex system had to be completely removed because of a sub-occlusive syndrome. Three patients had early infection requiring partial system removal (Varitensor). At the end of follow-up, 9 patients were cured (36%), 9 patients (36%) were significantly improved and 7 patients (28%) were not improved. Five patients are waiting for a new readjustment.

CONCLUSION

In this short series of patients who had prostatic surgery, at mid-term follow-up, the placement of a BSUA-R was associated with an improvement or cure of urinary incontinence symptoms in two-thirds of cases.

Stress Urinary Incontinence in Women With Multiple Sclerosis

Purpose

To report the prevalence and risk factors of stress urinary incontinence (SUI) and the prevalence of intrinsic sphincter deficiency in women with multiple sclerosis (MS).

Methods

We conducted a retrospective study. Female patients with MS, followed for lower urinary tract symptoms (LUTS) during a 15-year period were included. Demographic data, MS history, expanded disability status scale (EDSS) score at the urodynamic visit, obstetrical past, birth weight, LUTS, and urodynamic findings were collected. SUI was defined as incontinence during cough, or any effort. A maximum urethral closure pressure less than 30 cm H₂O defined intrinsic sphincter deficiency.

Results

We included 363 women with a mean age of 46.7±10.8 years and a mean disease duration of 12.9±8.7 years. The incidence of relapsing remitting MS, a secondary progressive form, and a primary progressive form was 60.6%, 32.8%, and 6.6%, respectively. The prevalence of SUI was 31.4%. The prevalence of intrinsic sphincter deficiency was 1.4% and 0.8% of these patients had a SUI (P=0.300). In a multivariate analysis, women with a SUI had significantly higher birth weight (P=0.030), a pelvic organ prolapse (P=0.021), urgent urinary incontinence (P=0.006), a lower EDSS score (P=0.019), and a weaker containing effort (P<0.001).

Conclusions

The prevalence of SUI in women with MS was 31.4%. This symptom could affect the quality of life of women with MS.

Sacral Neuromodulation in Urological Practice

Sacral neuromodulation (SNM) is a minimally invasive, restorative treatment to improve voiding and elimination functions. We give a historical perspective of SNM and explore the evidence for the use of this therapy for Food and Drug Administration-approved pathologies as well as disease processes that are being treated internationally. Ensuring optimal lead placement increases the potential of a comfortable, durable, and efficacious response. The future of SNM aims to maximize its potential benefit, refine its use, and minimize its risks and cost. Evolution of the therapy includes better device options, better software for patient and clinician use, more programming capabilities, and new nerve targets.

Histological and Urodynamic Effects of Autologous Stromal Vascular Fraction Extracted from Fat Tissue with Minimal Ex Vivo Manipulation in a Porcine Model of Intrinsic Sphincter Deficiency

PURPOSE

To evaluate the healing abilities of autologous stem cell therapy (stromal vascular fraction) prepared from adipose tissue we used an automated system without an ex vivo culture phase in a pig model of intrinsic sphincteric deficiency.

MATERIALS AND METHODS

A total of 15 pigs underwent endoscopic section of the urethral sphincter. Animals were then randomly assigned to 3 groups, including 1) controls without stromal vascular fraction injection, 2) early injection with stromal vascular fraction 2 to 3 days after section and 3) late stromal vascular fraction injection delivery 30 days after injury. Extraction and stromal vascular fraction injection were performed as a single procedure. The stromal vascular fraction was characterized by flow cytometry. Mesenchymal stem cell-like cells were enumerated by clonogenicity (cfu fibroblast) assay. Study end points included histological assessment of the urethral injury surface and urodynamics to determine maximum urethral pressure.

RESULTS

Flow cytometry analysis revealed a mesenchymal stem cell-like phenotype in a mean ± SD of 47.3% ± 11.8% of stromal vascular fraction cells. The cfu fibroblast frequency was 1.3 to 6.6/100 stromal vascular fraction cells (1.3% to 6.6%). Stromal vascular fraction injection was associated with a reduction of the urethral injury surface in the early and late injection groups compared with the respective controls (7% vs 17% and 1% vs 13%, p = 0.050 and 0.029, respectively). On day 30 after injection maximum urethral pressure was significantly higher in the injected groups than in the control group, that is 64% vs 50% of maximum urethral pressure on day 0 (p = 0.04).

CONCLUSIONS

These data demonstrate the ability of an autologous stromal vascular fraction to improve the urethral healing process in a large animal model of intrinsic sphincteric deficiency.

Results of sling surgery in a non-selected population

OBJECTIVE

To evaluate sling surgery in terms of effectiveness and quality of life, and describe the effects of confounding variables on outcomes.

METHODS

A retrospective cohort study using multiple validated questionnaires was conducted in a specialized pelvic floor center in the Netherlands. Women were enrolled after undergoing sling surgery between January 1, 2010, and January 31, 2012. In addition to the preoperative questionnaire, participants completed a questionnaire a minimum of 6weeks after surgery to assess outcomes.

RESULTS

Of 255 eligible participants, 228 (89.4%) returned the postoperative questionnaire after a mean follow-up of 14.9months (range 2-32). At the time of follow-up, 158 (69.3%) patients considered themselves cured, and an improvement was observed in 155 (68.9%) patients; 70 (31.1%) patients rated their postoperative situation as little improved, unchanged, or deteriorated. Compared with patients who had no history of previous related surgery, patients with prior sling surgery benefited significantly less from surgery, whereas those with concomitant vaginal surgery showed similar scores in all outcome parameters. A high body mass index was found to have a negative effect on the results of surgery.

CONCLUSION

midurethral sling surgery is both efficient and effective in curing stress urinary incontinence. However, patient characteristics and confounding variables can influence the outcome of surgery and should therefore always be discussed with the patient.

Urolastic for the treatment of women with stress urinary incontinence: 24-month follow-up

Introduction

To evaluate the efficacy and durability of Urolastic, a new urethral bulking agent in women with stress urinary incontinence (SUI), after a follow-up of 24-months.

Material and methods

A follow-up study of women with SUI who received a Urolastic injection and successfully passed the 12-month follow-up. Assessment included the Stamey Grade, 1-h Pad weight test, and the International quality of life (I-QoL) score.

Results

Nineteen women who completed the 12-month follow-up were invited for the 24-month follow-up study. One patient did not respond to the correspondence. Four of the 18 patients who responded to the correspondence reported removal of the Urolastic implant at another facility, based on their desire. The explanation for this removal was painful intercourse (n = 1) or less than optimal dryness (n = 3). The overall objective improvement in continence status at 24-months was 66% compared to the 89% at the 12-month follow-up, while in addition the 1-h pad weight test showed >50% reduction in pad weight in 66% of patients compared to 84% at the 12-month follow-up. Adverse events reported were urinary tract infection (n = 1), local genital infection with erosion into the vagina (n = 1), painful intercourse (n = 2), and urgency (n = 4).

Conclusions

Urolastic is comparable to other bulking agents in terms of durability, efficacy, and complications.

The investigation and treatment of female pelvic floor dysfunction

BACKGROUND

25% of all women report involuntary loss of urine, and 7% may require treatment.

METHODS

This review is based on a selection of pertinent literature, including guidelines and Cochrane reviews.

RESULTS

The assessment of pelvic floor dysfunction in women begins with a basic evaluation that is followed by special diagnostic tests if indicated. The physician taking the clinical history should inquire about the patient's behavior, personality, social and other stressors, and eating and drinking habits, as well as any mental disorders that may be present, including anxiety disorders, depression, somatization disorders, and disorders of adaptation. Conservative treatment consists mainly of lifestyle changes, physiotherapy, and medication. Stress incontinence is most commonly treated with pelvic floor exercises, with a documented success rate of 56.1% vs. 6% without such treatment (relative risk 8.38, 95% confidence interval 3.67-19.07). If incontinence persists, surgery may be indicated ( implantation of suburethral tension-free slings, or colposuspension). Feedback and biofeedback training can be used to treat an overactive bladder. If these techniques and drug therapy are unsuccessful, botulinum toxin injections can be considered.

CONCLUSION

Well-validated treatments for pelvic floor dysfunction are available. Psychosomatic factors must be taken into account and can have a major effect on treatment outcomes.

Meta-analysis of female stress urinary incontinence treatments with adjustable single-incision mini-slings and transobturator tension-free vaginal tape surgeries

Background

The study on SIMS and SMUS as a whole by Alyaa Mostafa et al showed that after excluding the TVT-S sling, there is no significant difference in patient-reported cure rate and objective cure rate between these two methods. In this paper, we systematically evaluate the relevant data on SIMS-Ajust and TVT-O/TOT and further confirm their safety and effectiveness, providing reliable clinical evidence.

Methods

By searching the Medline, Embase, Scopus, and Web of Science databases and the Cochrane Database of Systematic Reviews combined with manual searches, all reports on randomized controlled trials (RCTs) of single-incision mini-sling (SIMS-Ajust) and transobturator tension-free vaginal tape (TVT-O/TOT) surgeries were collected. Using RevMan 5.2 statistical software, the patient-reported cure rate, objective cure rate, operative time, postoperative pain, lower urinary tract injuries, groin pain, postoperative voiding difficulties, de novo urgency and/or worsening of preexisting surgery, vaginal tape erosion, repeated continence surgery, and other related data on both surgical methods were evaluated.

Results

A total of 154 relevant research reports were retrieved, and five randomized controlled trials were included in this study, involving a total of 678 patients. The meta-analysis results show no significant difference in the patient-reported cure rate and objective cure rate between SIMS-Ajust and TVT-O/TOT [RR = 0.95, 95 % CI (0.87 to 1.04), P > 0.05; RR = 0.97, 95 % CI (0.90–1.05), P > 0.05]. With respect to operation time and groin pain, SIMS-Ajust outperforms TVT-O/TOT [MD = −1.61, 95 % CI (−2.48 to 0.74), P < 0.05; RR = 0.30, 95 % CI (0.11 to 0.85), P < 0.05]. In terms of postoperative pain, lower urinary tract injuries, postoperative voiding difficulties, de novo urgency and/or worsening of preexisting surgery, vaginal tape erosion, and repetition of continence surgery, there is no significant difference between SIMS-Ajust and TVT-O/TOT [RR = 0.50, 95 % CI(0.18–1.43), P > 0.05; RR = 2.82, 95 % CI(0.14–57.76), P > 0.05; RR = 0.64, 95 % CI(0.28–1.45), P > 0.05; RR = 1.06, 95 % CI(0.66–1.71), P > 0.05; RR = 1.04, 95 % CI(0.24–4.45), P > 0.05; RR = 1.64, 95 % CI(0.41–6.61), P > 0.05].

Conclusions

SIMS-Ajust is safe and effective in the treatment of female stress urinary incontinence. Compared with TVT-O/TOT surgery, SIMS-Ajust surgery has the same high objective cure rate and patient-reported cure rate and low incidence of perioperative complications, in addition to its short operative time and low incidence of groin pain. Its long-term efficacy needs further observation.

[Intrinsic sphincter deficiency and female urinary incontinence]

OBJECTIVE

Stress urinary female incontinence (SUI) is primary due to intrinsic sphincter deficiency (ISD) and urethral hypermobility. Despite a lack of standardised international definition, ISD needs to be clearly diagnosed in order to be correctly treated. This work is an update about the female ISD produced from a review of a published article.

MATERIAL AND METHODS

This review of article published on this subject in the Medline (Pubmed database), selected according to their scientific relevants, of consensus conferences and published guidelines, has been performed by the committee for women pelvic floor surgery of the French Urological Association.

RESULTS

Although there is no international consensus definition, we can consider that the ISD is a composite concept combining urodynamic data (MUCP < 20 or 30 cmH20) and one or more clinical information (no urethral mobility, negative urethral support test, failure of a first surgery, leakage during abdominal straining, high stress incontinence scores). Imaging can provide additional evidence for intrinsic sphincter deficiency diagnosis, but the correlation between imaging and function remains low. By standardizing methodology and interpretations to better diagnose women with ISD, it may be possible to improve preoperative planning and outcomes for these patients. A retropubic midurethral sling can be performed as a first surgery. In case of a lack of urethral mobility, the artificial urinary sphincter (AUS) remains the gold standard. Adjustable continence therapy (ACT(®)) can be proposed as an alternative option. The efficacy and safety of muscle-derived cell therapy in ISD needs more studies. Injection of bulking agents may be an option according to the severity and the expectations of the patient. Bladder overactivity needs to be treated as first-line in case of mixed urinary incontinence. In elderly women, a careful evaluation of the bladder contractility and comorbidity must be performed. A geriatric evaluation can be necessary.

CONCLUSION

Clinical and paraclinical assessment allow to confirm the diagnosis of female ISD, to estimate its severity, and to identify associated mechanisms of incontinence (urethral hypermobility, bladder overactivity) to choose the most adapted treatment.

[Treatment of female stress urinary incontinence. Value of classical incontinence operations]

BACKGROUND

Fascial sling and the colposuspension were considered standard operations in the therapy of female stress urinary incontinence until the mid-1990s. New surgical procedures were compared with these techniques in regard to cure rate and long-term results.

RESULTS

Nowadays fascial slings are rarely performed. Colposuspension - despite comparable results - was replaced by tension-free tapes as the new gold standard. This is not due to lower efficacy, but predominantly due to reduced surgical trauma, simple use, and rapid convalescence. However, in cases of recurrence and the combined treatment of prolapse, colposuspension is still used.

Reconstructive surgery for male stress urinary incontinence: Experiences using the ATOMS(®) system at a single center

OBJECTIVE

To propose possible success-driven solutions for problem and complication rates encountered with the ATOMS(®) sling system, based on first-hand experience; and to provide possible actual alternative scenarios for the treatment of male stress urinary incontinence (SUI).

PATIENTS AND METHODS

During the defined period (between 4/2010 and 04/2014), 36 patients received ATOMS(®) system implants at our clinic. We collected pre- and post-operative evaluation data using the International Consultation on Incontinence Questionnaire Short Form (ICIQ SF). As an expansion of the questionnaire, we added questions about post-operative perineal pain, the general satisfaction with the results of the intervention and willingness to recommend the operation to a best friend.

RESULTS

Our data shows a relatively high explantation rate, but a surprisingly high patient satisfaction rate. Explantation was required mainly due to late onset infections or other symptomatic factors. Compared to other studies early onset infections were rare.

CONCLUSION

A non-invasive, uncomplicated adjustable system to alleviate male stress urinary incontinence remains a challenge. Although there are various systems available for the treatment of male stress urinary incontinence, it seems that despite the advantages of the ATOMS(®) system, an artificial sphincter system may pose more advantages based on our experience, understanding and knowledge of its well-documented long-term solutions and problems.

Pre-operative training induces changes in the histomorphometry and muscle function of the pelvic floor in patients with indication of radical prostatectomy

OBJECTIVE

To evaluate the efficacy of preoperative pelvic floor muscle training (PFMT) on histomorphometry, muscle function, urinary continence and quality of life of patients undergoing radical prostatectomy (RP).

MATERIAL AND METHODS

A prospective intervention clinical study was designed in 16 patients with indication of RP who were randomized into two groups. The Control Group received routine pre-surgical education (hygienic-dietary measures). The intervention group received a training session with supervised PFMT, three times a day, for four weeks, 30 days before the PR. Muscle function of the external urethral sphincter, contraction pressure of the levator ani, urinary continence and quality of life related to health (HRQoL) were evaluated before and after the intervention. At the end of the intervention and day of the surgery, samples of residual muscle tissue were obtained from the external sphincter muscle of the urethra for histomorphometric analysis.

RESULTS

After the intervention, those participants who carried out PFMT showed an increase in the cross-sectional area of the muscle fibers of the external urethral sphincter (1,313 ± 1,075 μm(2)vs. 1,056 ± 844 μm(2), P=.03) and higher pressure contraction of the levator ani (F=9.188; P=.010). After catheter removal, 62% of patients in the experimental group and 37% in the control group showed no incontinence. After removal of the catheter, 75% of the experimental group did not require any pad compared to 25% in the control group (p=NS). There were no significant differences between the two groups in any of the HRQoL domains studied.

CONCLUSIONS

Pre-surgical PFMT in patients with RP indication induces changes in the histology and function of the pelvic floor muscles, without changes in urogenital function and HRQoL. These results provide new evidence regarding the benefit of PFMT in preventing RP associated complications.

The surgical trends and time-frame comparison of primary surgery for stress urinary incontinence, 2006-2010 vs 1997-2005: a population-based nation-wide follow-up descriptive study

INTRODUCTION AND HYPOTHESIS

The purpose of our study was to describe the surgical trends for female stress urinary incontinence (SUI) during 2006-2010, and a time-frame comparison with 1997-2005, based upon the National Health Insurance (NHI) claims data in Taiwan.

METHODS

Women who underwent various primary surgeries for SUI during 2006-2010 were identified, with a total of 15,099 inpatients. The variables included surgical types, patient age, surgeon age and gender, specialty, and hospital accreditation levels. Chi-squared tests and SAS version 9.3.1 were used for statistical analysis.

RESULTS

During the follow-up study, midurethral sling (MUS) application increased significantly from 53.09 % in 2006 to 78.74 % in 2010. It was associated concomitantly with a decrease in retropubic urethropexy (RPU) from 29.68 % to 12.99 %, and pubovaginal sling treatment (PVS) from 9.33 % to 3.46 %. MUS was most commonly used among all patients' and surgeons' age groups, and different accreditation hospital levels. MUS was more commonly used by gynecologists (71.38 %) than urologists (57.91 %); while PVS and periurethral injection were more commonly performed by urologists than gynecologists. Similar surgical trends were found during time-frame comparison, 2006-2010 vs 1997-2005. SUI surgeries increased in patients aged ≥60, surgeons aged ≥ 50, and in regional hospitals.

CONCLUSION

This follow-up study depicts the increase in popularity of MUS and offers evidence of surgical trends and a paradigm shift for female SUI surgery. More older women were willing to seek healthcare and undergo surgery. The surgical skills and knowledge spread from medical centers into regional hospitals. The time-frame shift may have a profound impact on patients, as well as the healthcare providers.
