The male sling for post-prostatectomy urinary incontinence: a review of contemporary sling designs and outcomes

Effect of a Modified Technique of Posterior Reconstruction by Iliopectineal Ligament Suspension During Robot-assisted Laparoscopic Radical Prostatectomy on Early Continence: A Randomised Controlled Trial

OBJECTIVE

To evaluate the effect of a modified technique of posterior reconstruction by iliopectineal ligament suspension during robot-assisted radical prostatectomy (RARP) on recovery of early continence.

METHODS

A prospective, single surgeon, single centre, randomised controlled trial was performed from August 2018 to March 2020 with 171 patients (92 control vs 79 experimental). The posterior reconstruction was done using a standard technique in the control group and was modified for the experimental group by incorporating not only the "Rocco" stitch between Denonvilliers' fascia and the rhabdosphincter but also the iliopectineal ligaments bilaterally to further improve posterior support with this suspensory 'hammock'. Both groups of patients were followed for a year with questionnaires and 24-hour pad tests.

RESULTS

Both groups were comparable in terms of baseline demographic, clinical, and pathological characteristics. With regards to recovery of urinary continence, no statistically significant differences were found for socially continent (0-1 pads per day) or fully continent (0 pads per day) rates at all time points examined (1, 3, 6, 12 months). Moreover, there were no statistically significant differences between the groups for presence of urinary symptoms, bowel symptoms, sexual function, and hormonal symptoms.

CONCLUSION

The modified technique of posterior reconstruction by iliopectineal ligament suspension is not associated with improved early continence as compared to the standard posterior reconstruction technique during RARP. Future studies may want to explore other variations of suspensory sutures that could strengthen posterior urethral support to achieve earlier recovery of continence.

Adjustable Male Sling for The Treatment of Postprostatectomy Stress Urinary Incontinence: Intermediate-Term Follow-Up Results

Objective To evaluate the outcomes of adjustable male sling (Argus®) implantation in the management of post-prostatectomy incontinence (PPI) with intermediate-term follow-up results. Materials and methods The data on adjustable male sling surgery between September 2015 and September 2020 were retrospectively analyzed. Patients were preoperatively evaluated with a voiding diary, 24-hour pad test, and validated questionnaire. Functional outcomes were also evaluated using 24-hour pad requirement and pad weight, and the International Consultation on Incontinence (ICIQ-SF) score. Results A total of 16 patients (eight having undergone the transurethral resection of the prostate [TUR-P] and eight radical prostatectomy [RP]) were enrolled in the study. Thirteen patients had moderate (81.25%) PPI, and three patients (18.75%) had severe PPI. With the mean follow-up of 36.9±14.3 months, nine patients (56.2%) were noted as cured and four (25%) as improved, with an overall success rate of 81.2%. At the last follow-up visit, the median number of pads used per day decreased from 3.5 to 1, and the 24-hour pad test result decreased from 300 to 50 gr (p < 0.001 and p < 0.001, respectively). The ICIQ-SF score decreased from the initial mean of 15.8 ± 2.3 to 7.1 ± 6.6 (p < 0.001). When the outcomes were compared according to the etiology, there was no statistically significant difference (p = 0.522). Conclusions Male sling surgery can be performed safely in patients with moderate and severe stress urinary incontinence with low complication and high success rates. The results of TUR-P-related PPI are similar to those of surgery performed due to the etiology of RP.

Valsalva leak point pressure (VLPP) greater than 70 cm H2O is an indicator for sling success: a success prediction model for the male transobturator sling

INTRODUCTION AND OBJECTIVES

Urodynamic studies are often performed in the evaluation of post-prostatectomy urinary incontinence (PPUI). The male transobturator sling (TOS) is a minimally invasive treatment for PPUI. Others have reported their results with a specific Valsalva leak point pressure (VLPP) that predicts a good outcome with the male TOS. Our objective was to determine the relationship of the pre-operative VLPP on the success rate of the male TOS in a high-volume, single center. We hypothesized that a higher pre-operative VLPP better predicts successful outcomes.

METHODS

We reviewed patients undergoing a male TOS placement from 2006 to 2012 at our institution. Patients who underwent TOS placement were identified using our patient data portal (DEDUCE). Demographic, urodynamic, and follow-up data were extracted by chart review. Post-operative success was defined by the use of 0 or 1 security pad, a negative stress test on exam, or pad weight of less than 8 g per 24 h. Cox and linear regression models were performed.

RESULTS

290 patients were included. All patients underwent a radical prostatectomy for prostate cancer and presented with PPUI. Mean age at surgery was 66.3 (± 7.4) years and 84% were Caucasian. Median time to follow-up was 5 months (IQR 1-15). A linear regression model shows an inverse prediction curve for sling failure versus VLPP (p = 0.02). The hazard ratio for failure with a VLPP of ≤ 70 cm H₂O compared with a VLPP of > 70 cm H₂O, adjusted for pelvic radiation and 24-h pad weight was 0.5 (95% CI 0.2-0.98).

CONCLUSION

Patient selection is imperative in the success of the male TOS for patients with PPUI. In our cohort of patients with PPUI, those with a pre-procedural VLPP of > 70 cm H₂O were 50% less likely to fail after TOS placement versus those with a VLPP ≤ 70 cm H₂O. In our practice, we use these data to support the use of VLPP cut off of 70 cm H₂O as an indicator for success to help in the evaluation and counseling of patients.

[Künstliche Harnsphincter zur Behandlung von Stress-Harninkontinenz - eine oft nicht ausgelastete Behandlungsoption in Deutschland]

ABSTRAKT

Harninkontinenz ist in Deutschland weit verbreitet und betrifft Millionen von Frauen und Männern. Vor allem Männer, die postoperativ dauerhaft inkontinent sind, werden hierzulande trotz der ausreichenden Verfügbarkeit chirurgischer Optionen unterbehandelt. Der künstliche Schließmuskel wird seit Jahrzehnten erfolgreich zur Behandlung angeborener und erworbener Stress-Harninkontinenz bei Männern und Frauen sowie neurogener Harninkontinenz eingesetzt und wird in Form neuer Modelle weiterentwickelt. Aufgrund der guten Ergebnisse, Es gilt jetzt als Standardtherapie für Männer mit anhaltender, mittelschwerer bis schwerer Harninkontinenz. Die operationstechnische Technik ist anspruchsvoll, kann aber erlernt werden. Die meisten Komplikationen können in erfahrenen Händen deutlich reduziert werden. Patientenzufriedenheit mit künstlichen Harnsphinctern (AUS) ist hoch und korreliert mit der Kontinenzrate und nicht mit der relativ hohen Revisionsrate, weshalb diese Behandlungsoption in Deutschland zunehmend mehr Patienten mit mittelschwerer bis schwerer Harninkontinenz angeboten werden sollte. Urologen in der allgemeinen Praxis spielen in diesem Zusammenhang eine zentrale Rolle.

Complications after male adjustable suburethral sling implantation

Introduction

Argus suburethral sling implantation is a minimally invasive operation with the possibility to adjust the tension of the sling at any time after the procedure, which provides good treatment results for male stress urinary incontinence (SUI).

Aim

To determine the predictive factors, the incidence, severity and timing of the onset of complications after Argus sling implantation for males with post-operative SUI.

Material and methods

A total of 41 patients who underwent Argus sling implantation due to post-operative SUI were included. Median follow-up was 12 months. All complications were captured and graded according to severity and classified by timing of onset. Logistic regression analysis was performed to identify predictors of the most common side effects.

Results

Overall 22 (54%) of 41 males have experienced 31 complications. Three (7%) patients have experienced only intra-operative, 16 (39%) patients only post-operative and 3 (7%) patients both intra-operative and post-operative complications. The most common intra-operative complications were bladder perforation (12%) and external iliac vein injury (5%), while post-operative complications were acute urinary retention (29%), infection (10%) and perineal pain (7%). Previous radiotherapy has significantly increased the risk of intra-operative complications, while a non-significant tendency was observed for younger age, previous androgen deprivation therapy and grade 3 SUI. In terms of severity, most post-operative complications were classified as grade 3 according to the modified Clavien-Dindo system.

Conclusions

Argus sling implantation provides a tolerable complication rate, where acute urinary retention was the most common side effect. Previous radiotherapy significantly increases the risk of serious intra-operative complications.

[Retrospective multicentric evaluation of the efficacy of four-arms and adjustable male slings in the management of mild and moderate urinary incontinence after radical prostatectomy]

INTRODUCTION

Objective of the study to carry out a retrospective multicentric evaluation of the efficacy of male slings in the management of mild and moderate urinary incontinence after radical prostatectomy.

METHOD

We performed a multi-center study that included all patients with mild to moderate urinary stress incontinence after radical prostatectomy with adjustable slings or four-arm slings. We collected the number of protections before the procedure and one year after the application of the male sling.

RESULTS

A 4 arms or adjustable sling was put to 65 men. The cure rate was 33.3% (n=5) for Remeex, 52% (n=13) for TOMS, and 46.7% (n=12) for Virtue (P=0.07). The failure rate was 26.7% (n=4) for Remeex, 24% (n=6) for TOMS, and 40% (n=10) for Virtue (P=0.18). The overall complication rate was 40% (n=6) for Remeex, 28% (n=7) for TOMS, and 16% (n=4) for Virtue (P=0.19).

CONCLUSION

This multicentric retrospective series confirms that male slings are a usefull therapy for patients with mild or moderate urinary incontinence.

Preoperative pad usage is independently associated with failure of non-adjustable male trans-obturator slings in otherwise well-selected patients

INTRODUCTION

Our objective was to determine which clinical factors are associated with failure to achieve continence after nonadjustable trans-obturator sling in otherwise well-selected men undergoing treatment for post-prostatectomy incontinence (PPI).

METHODS

A retrospective review of AdVance/AdVance™ XP male sling procedures was performed from December 2006 to May 2017. Patients with known risk factors for sling failure, including severe incontinence (>5 pads), radiation therapy, or detrusor dysfunction, were excluded. The primary outcome was failure to achieve continence, defined as ≤1 pad per day when pad use was ≥2 preoperatively (or 0 pads if preoperative pad use was 1). Covariates included patient age, Charlson comorbidity index (CCI), diabetes, obesity (body mass index [BMI] ≥35), type of prostatectomy, and number of preoperative pads. Descriptive statistics and Cox regression analysis was performed.

RESULTS

Of 158 patients, continence was achieved in 82.3% (n=130) with a mean followup of 42.7 months. Patient-reported satisfaction was 86.7% (n=137) and the 90-day complication rate was 12% (n=19). On univariate Cox regression analysis, increasing age (p=0.02), CCI (p=0.02), and preoperative pad use (p<0.0001) were associated with sling failure, whereas obesity (p=0.95), diabetes (p=0.49), and type of prostatectomy (p=0.88) were not. On multivariate analysis, only increasing preoperative pad use remained associated with sling failure (hazard ratio [HR] 1.3; 95% confidence interval [CI] 1.1-16; p=0.008). Patients wearing >3 pads per day were more likely to experience failure (35.5% vs. 13.4%; p=0.007).

CONCLUSIONS

Increasing preoperative pad use is independently associated with an increased risk of failure after non-adjustable sling for post-prostatectomy incontinence in otherwise well-selected patients.

Treatment of stress urinary incontinence after prostatectomy with the adjustable transobturator male system (ATOMS®) with preattached scrotal port

INTRODUCTION

Stress urinary incontinence (SUI) is a significant sequela of prostate cancer surgery. In this article, we present the surgical technique and safety and efficacy of the adjustable transobturator male system (ATOMS®) with preattached scrotal port.

MATERIAL AND METHOD

An open prospective study was conducted at a university hospital with the main objective of changing the baseline condition after adjustment in the daily pad count and their wet weight (pad test). The secondary objectives were the quality-of-life assessment (International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF] and Incontinence Impact Questionnaire-7 [IIQ-7], baseline and after the adjustment), patient-perceived results (Patient Global Index [PGI] and Global Response Assessment [GRA] at 1 year) and assessment of complications according to Clavien-Dindo. The numerical values are expressed in median ± IQR.

RESULTS

We analysed 60 consecutive patients with a follow-up of 21±22 months. The baseline pad-test was 465±450mL, and the pad-count was 5+3 pads/day. The baseline SUI was mild (11.6% of patients), moderate (25%) and severe (63.3%). The operative time was 60±25min, the hospital stay was 1±0 days, and the visual analogue scale of pain on day 1 after surgery was 0±1. The total filling was 16.5±7mL, and the number of refillings was 1±2. The pad-test and pad-count after the adjustment were 0±20mL and 0±1, respectively (both p<.0001 compared with baseline). SUI disappeared (81.7%) or remained mild (11.7%), moderate (5%) or severe (1.6%). We observed a reduction in the ICIQ-SF (p<.0001) and IIQ-7 scores (p=.0003). Both continence (p=.002) and satisfaction (p=.03) were lower in the irradiated patients. Complications occurred in 11 cases (18.6%), 8 (13.5%) of which were grade I and 3 (5.1%) of which were grade 3. The treatment satisfaction rate was 91.7%, and the patient-perceived overall improvement at 1 year was highly pronounced (PGI-I score, 1±1; GRA, 6±1).

CONCLUSIONS

SUI treatment of men using third-generation ATOMS® is safe and effective in the short-term, even in patients with severe SUI. The rate of dry patients after the adjustment exceeded 80%, and the satisfaction rates exceeded 90%. The patients assessed this treatment highly positively.

Clinical results of a dorsally positioned hydraulic ID-sling in male patients with post-prostatectomy-incontinence

PURPOSE

To prospectively evaluate the effectiveness and safety of and the long-term experience with a re-adjustable hydraulic sling (ID-sling) device positioned dorsally to the urethra for the treatment of male post-prostatectomy incontinence (PPI).

MATERIALS AND METHODS

Between September 2007 and November 2009 13 patients with persisting SUI were treated consecutively with an ID-sling™ in two European tertiary centers by a single surgeon. Physical examinations and standardized questionnaires (ICIQ-SF + VAS), pad tests, and 24-h pad number counts were performed at baseline and during follow-up.

RESULTS

The implantation of the hydraulic cuff was uncomplicated in all cases. The ICIQ-SF score diminished from a preoperative mean value of 18 to a mean of five postoperatively. One patient remained completely dry with normal micturition. All patients demonstrated a mild improvement at primary filling but did not show any significant improvement after the second or any subsequent filling. In total, 1/13 (7.7%) patients were completely dry and 5/13 (38.4%) showed improved continence. In 6/13 (46.2%) patients, satisfactory continence results according to subjective criteria, were not achieved. Subsequently, artificial urinary sphincter (AUS) implantation was offered to one patient (7.7%) after 12 months and to ten patients (76,9%) after 24 months.

CONCLUSIONS

The implantation of a dorsally placed hydraulic sling is a not yet standardized and complex procedure, even for the experienced surgeon. To date, this implantation method is not an alternative to other devices. An improved sling design is necessary to simplify the surgical procedure and to improve long-term stability.

Treatment of male stress urinary incontinence with the adjustable transobturator male system: Outcomes of a multi-center Iberian study

AIM

To evaluate effectiveness and safety of the adjustable transobturator male system (ATOMS) for male stress urinary incontinence (SUI).

MATERIAL AND METHODS

A retrospective multicenter study was conducted in nine Iberian institutions using a board-approved database for 215 patients intervened between 2012 and 2017, with no case excluded. Continence status, patient satisfaction, number, and grade of complications (Clavien-Dindo) and factors affecting dry rate at adjustment were evaluated. Multivariate analysis defined the population at best success rate. Incontinence recurrence due to device failure and/or explant was evaluated and Kaplan-Meier curve for durability performed.

RESULTS

Adjustment was achieved at a mean 1.4 ± 1.9 fillings. Dry-rate after adjustment was 80.5% (96.2% mild and 75.3% moderate-severe), 121 (56.3%) used no pads, and 52 (24.2%) a security pad with urine loss under 10 mL. Mean basal daily pad-test and pad-count decreased from 484 ± 372.3 mL and 3.9 ± 2 pads to 63.5 ± 201.2 mL and 0.9 ± 1.5pads (both P < 0.0001). Satisfaction rate was 85.1% (94.3% mild and 82.1% moderate-severe). Factors associated to dryness were: lesser severity of SUI (P < .0001), absence of radiotherapy (P = 0.0002) and device generation (P = 0.05). Multivariate analysis revealed absence of radiation (OR = 3.12; 1.36-7.19), mild (OR = 19.61; 3.95-100), and moderate (OR = 2.48; 1.1-5.59) SUI were independent predictors. Complications presented in 33(15.35%); 66.7% grade 1, 9.1% grade 2, and 24.2% grade 3. At 24.3 ± 15 mo mean follow-up device was explanted in seven (3.25%) and SUI worsened after adjustment in nine (4.2%). Dry-rate at follow-up was 73% and durability of device in dry patients at adjustment was 89.8% (82.9-94) at 2-years.

CONCLUSIONS

This study confirms ATOMS device is safe and achieves high treatment efficacy and patient satisfaction in a multicenter setting. Significantly better results are achieved in less severe and non-irradiated cases. Durability of the device is reassuring in the short-term.

Long-term results of the implantation of the AMS 800 artificial sphincter for post-prostatectomy incontinence: a single-center experience

OBJECTIVES

Report the long-term outcomes of the AMS 800 artificial sphincer (AS) for the treatment post-prostatectomy incontinence (PPI) in a single center in Brazil.

MATERIALS AND METHODS

Clinical data from patients who underwent the procedure were retrieved from the medical records of individuals with more than 1 year of follow-up from May 2001 to January 2016. Continence status (number of pads that was used), complications (erosion or extrusion, urethral atrophy, and infection), malfunctions, and need for secondary implantation were evaluated. The relationship between complications and prior or subsequent radiation therapy (RT) was also examined.

RESULTS

From May 2001 to January 2016, 121 consecutive patients underwent AS implantation for PPI at an oncological referral center in Brazil. At the last visit, the AS remained implanted in 106 patients (87.6%), who reported adequate continence status (maximum of 1 pad/day). Eight-two subjects (67.8%) claimed not to be using pads on a regular basis at the final visit (completely dry). Revision occurred in 24 patients (19.8%).Radiation therapy (RT) for prostate cancer following radical prostatectomy was used in 47 patients before or after AS placement. Twelve patients with a history of RT had urethral erosion compared with 3 men without RT (p=0.004).

CONCLUSION

Considering our outcomes, we conclude that AS implantation yields satisfactory results for the treatment of PPI and should remain the standard procedure for these patients. Radiation therapy is a risk factor for complication.

Retrograde leak point pressure measurement improves outcomes of the Virtue male sling for postprostatectomy incontinence

INTRODUCTION

We aimed to compare the efficacy of two different sling tensioning approaches, and to report our experience, including safety and impact on quality of life (QoL) of the Virtue^® male sling for the treatment of postprostatectomy incontinence (PPI).

METHODS

From our prospectively maintained database, we retrospectively identified all men treated with the Virtue male sling for PPI between March 2009 and February 2014 by two urologists in two institutions. Baseline demographic data and the sling tensioning method were abstracted from the database. Likewise, the Patient Global Impression of Improvement (PGI-I) scale, severity of incontinence, and clinical outcomes were also abstracted.

RESULTS

48 patients were treated with the Virtue quadratic male sling. Sling tensioning was done using cystoscopy in the first 18 patients (Group 1), while per-operative retrograde leak point pressure (RLPP) measurement was done in the last 30 patients (Group 2). The median (interquartile range [IQR]) followup from the day of surgery was 22 (15-41) months. At the last followup visit, 7 (39%) patients in Group 1 were cured or improved of their PPI, compared to 21 (70%) patients in Group 2 (p=0.03). The final median (IQR) RLPP in these patients was 41 (37-48) cm H₂O. Transient pain was the most common adverse event, occurring in 23 (48%) of patients. Twenty-one (70%) patients in Group 2 were "much better" or "very much better" with their device, compared to 7 (39%) in Group 1 (p=0.0008).

CONCLUSIONS

The Virtue male sling is a valuable treatment option for PPI. Per-operative RLPP measurement significantly improves cure and satisfaction rates.

Management of Male and Female Neurogenic Stress Urinary Incontinence in Spinal Cord Injured (SCI) Patients Using Adjustable Continence Therapy

Introduction

Artificial urinary sphincter (AUS) is an option for the treatment of neurogenic stress urinary incontinence (nSUI), but complications and re-operation rates are high, and there is no clear indication from guidelines ( 1 ). The aim of our study is to evaluate the effectiveness of a less invasive continence device in neurogenic population: Adjustable Continence Therapy ProACT/ACT®.

Methods

We retrospectively includedpatients with spinal cord injuries in this study, complaining of nSUI and treated at our Institution with Pro-ACT/ACT® implantation. Diagnosis of nSUI was achieved with clinical history data collection and video-urodynamic testing.

Results

We treated 13 males and 3 females by proACT/ACT device, mean age 47.5 years (range 27-71). Fifteen implantations were performed bilaterally under spinal anesthesia and under fluoroscopic control; in one male patient, only the right balloon was implanted. Mean refilling number was 2.8 (range 0-6), and mean final volume was 3.6 ml. No patient reported any perioperative complications according to Clavien-Dindo. Follow-up was 37 months (range 7-156). Five patients (31%) underwent device explantation for deflate in one case, erosion or migration in three cases (18%), and infection in one case. About 43.75% of patients were dry and 18.75% improved more than 50% their urine loss, 37.5% of patients improved less than 50%, and no one reported worsening of incontinence.

Conclusions

Implantation of proACT/ACT® device is safe and a minimally invasive procedure also in neurological patients, with a relative low rate of intra and postoperative complications. Efficacy is good, although slightly lower than the results in non-neurological patients.

Therapeutic Efficacy of a New Procedure for Male Urinary Incontinence Combining a Suburethral Polypropylene Mesh and Cardiovascular Patch

PURPOSE

Stress urinary incontinence (SUI) in men is a complication secondary to prostatectomy or resulting from neurological lesions. This study presents our experiences with male suburethral slings over the past decade.

METHODS

In this study, we considered patients who presented with SUI and were diagnosed with an intrinsic sphincteric deficiency due to postprostatectomy incontinence (PPI) or other causes (non-PPI). Patients who underwent the suburethral sling procedure using a polypropylene mesh and a cardiovascular patch were retrospectively included. An urodynamic study was performed before and after the operation. Global response assessment (GRA) and SUI grading were used for surgical outcome. The revision rate and the infection rate were also evaluated.

RESULTS

A total 31 patients were enrolled in this study; the mean patient age was 59.5±18.9 years, and the mean follow-up period was 36.9±29.4 months. Fourteen patients comprised the non-PPI group and 17 were in the PPI group. The preoperative SUI of all patients were categorized as a moderate to severe problem according to the SUI grade, with a mean score of 2.32±0.48 before the operation and 0.48±0.57 after the operation. With a mean score of 2.35±0.71, GRA showed that the patients were satisfied with the treatment. After the sling procedure, 4 patients (13%) reported a mild improvement, 12 (38.7%) a moderate improvement, while 15 (48.4%) reported an excellent improvement. Six patients (19.4%), including 5 from the non-PPI group (35.7%) and 1 (5.9%) from the PPI group (P=0.037), underwent sling removal because of infection.

CONCLUSIONS

The male suburethral sling procedure using a polypropylene mesh and a cardiovascular patch is a safe, efficacious, and inexpensive surgical procedure for PPI. In cases of neurological incontinence, however, the higher infection rate in non-PPI patients means that they should be carefully managed.

Sling Surgery for the Treatment of Urinary Incontinence After Transurethral Resection of the Prostate: New Data on the Virtue Male Sling and an Evaluation of Literature

OBJECTIVE

To provide a review of literature regarding the role of male slings in the treatment of stress urinary incontinence (SUI) following a transurethral resection of the prostate (TURP) and to evaluate the effects of the Virtue male sling in patients with post-TURP SUI.

MATERIALS AND METHODS

A systematic review of literature was performed to identify all papers on the use of male slings in patients with post-TURP SUI. Second, a prospective cohort study was conducted on 8 patients who received the Virtue as surgical treatment of post-TURP SUI. Questionnaires were collected preoperatively and 1, 3, 6, and 12 months postoperatively. Success and improvement were defined as pad usage (0 pads: success, pad reduction of ≥50%: improvement). Primary end point was the continence rate 1 year postoperatively. Data were analyzed using the paired 2-tailed t test.

RESULTS

Sling surgery appears to be significantly less successful in the treatment of SUI post TURP when compared to other types of prostate surgery. The clinical trial on the Virtue sling observed continence in 4 of 8 patients, with another 2 patients with improved continence after 1-year follow-up. No difference in success was observed between patients with mild and patients with severe SUI.

CONCLUSIONS

Little is currently known about the effects of sling surgery in patients with mild to severe SUI following a TURP. Although the Virtue male sling seems to be an efficient and safe device in the treatment of this complication, longer follow-up and larger cohorts will be needed to further confirm these results.

Mid-term outcomes of a male retro-urethral, transobturator synthetic sling for treatment of post-prostatectomy incontinence: Impact of radiotherapy and storage dysfunction

PURPOSE

To determine mid-term durability of the AdVance sling for post-prostatectomy incontinence (PPI) and impact of prior radiotherapy and storage dysfunction.

METHOD

Eighty men undergoing AdVance sling for PPI during 2008-2013 were reviewed. Pre-op urodynamics, pre and post-op pad usage, prior radiotherapy, and PGI-I scores were recorded.

RESULT

Mean follow-up was 36 months (range 14-72). Twelve men had radiotherapy pre-op, 10 had detrusor overactivity (DO), and 20 reduced compliance. Pre-op mean 24-hr pad weight was 264 g and mean pads-per-day (PPD) 2.60 ± 0.29. In the early post-op period (3-6 months), mean PPD was 0.40 (SD 0.16); at mid-term follow-up mean PPD was 1.02 ± 0.31. Radiotherapy and DO were independently predictive of poor mid-term outcome. Men with DO or radiotherapy were using 1.03 ± 0.42 (P = 0.019) and 1.17 ± 0.41 (P = 0.02) more PPD, respectively than men without these factors. At mid-term follow-up, men without radiotherapy or DO were using 1.98 ± 0.28 less PPD compared to pre-operatively (P < 0.0001); with radiotherapy or DO men were using 0.73 ± 0.38 (P = 0.057) and 0.72 ± 0.43 (P = 0.092) less PPD, respectively. PGI-I score for men without radiotherapy or DO was 1.98 ± 0.40 ("much better"); with radiotherapy or DO PGI-I score was 3.80 ± 0.49 ("no difference").

CONCLUSION

The AdVance sling provides mid-term improvement in men with PPI. However, men with radiotherapy or DO have significantly poorer outcomes with mid-term results indicating a return to baseline degree of incontinence. Caution should be taken when considering the AdVance sling in these men. Pre-op urodynamics in men with radiotherapy and/or overactive bladder may be important when considering men for AdVance sling.

Long-term Follow-up of the Virtue Quadratic Male Sling

OBJECTIVE

To report our long-term outcomes of Virtue Quadratic (VQ) sling since male slings have been introduced as a potential alternative treatment option to the artificial urinary sphincter (AUS), with limited long-term data available for proof of efficacy. Herein, we report our data.

METHODS

A retrospective review was performed on all Virtue slings performed at our institution over a 2-year period. Patient-reported outcomes regarding procedure success, complications, as well as subsequent procedures were identified. Procedure failure was defined as the inability to reduce patient's preoperative pad use, sling explant for complications, and need for AUS due to continued incontinence.

RESULTS

We identified 32 consecutive male patients who were implanted with the VQ sling over the study period. One patient was excluded due to no follow-up. Median follow-up was 55 months. Median preoperative and postoperative pads per day were 3 (interquartile range: 1-3) and 2 (1-2.5). There were 21 (68%) patients who were considered procedure failures. Two (7%) patients reported chronic pain following placement and 7 (22%) underwent subsequent sling explant due to pain or for failure (1 vs 6). Six (20%) patients underwent subsequent AUS placement. Failure was more likely in patients with external beam radiation therapy (6, 19%) (P = .02). There was no association between procedure failure with age (P = .65) or severity of incontinence (P = .17).

CONCLUSION

This study demonstrated a significant procedure failure and complication rate with the VQ sling. Thus, we do not recommend the use of the VQ sling and have abandoned all further implantation of the device.

The artificial urinary sphincter and male sling for postprostatectomy incontinence: Which patient should get which procedure?

Surgery is the most efficacious treatment for postprostatectomy incontinence. The ideal surgical approach depends on a variety of patient factors including history of prior incontinence surgery or radiation treatment, bladder contractility, severity of leakage, and patient expectations. Most patients choose to avoid a mechanical device, opting for the male sling over the artificial urinary sphincter. The modern male sling has continued to evolve with respect to device design and surgical technique. Various types of slings address sphincteric incompetence via different mechanisms of action. The recommended surgery, however, must be individualized to the patient based on degree of incontinence, detrusor contractility, and urethral compliance. A thorough urodynamic evaluation is indicated for the majority of patients, and the recommendation for an artificial urinary sphincter, a transobturator sling, or a quadratic sling will depend on urodynamic findings and the patient's particular preference. As advancements in this field evolve, and our understanding of the pathophysiology of incontinence and mechanisms of various devices improves, we expect to see continued evolution in device design.

Male Readjustable Sling (MRS) System for Postprostatectomy Incontinence: Experiences of 2 Centers

OBJECTIVE

To evaluate the outcomes of Male Readjustable Sling (MRS) in patients with postprostatectomy incontinence at 2 unrelated centers and to determine preoperative factors relevant to the outcome.

MATERIALS AND METHODS

From January 2007 to January 2014, a total of 64 men with urinary incontinence following radical prostatectomy were treated with MRS at 2 centers. Patients were evaluated based on medical history, daily pad usage, urodynamics, and cystoscopy. The clinical outcome was evaluated according to daily pad usage and questionnaires. Success was defined according to reductions in the number of pads used per day after surgery, and factors related to surgical outcome were investigated.

RESULTS

The median age of the patients was 70 years (range: 53-84), and the mean follow-up duration was 46.0 ± 19.47 months (range: 12-89). During follow-up, readjustment of the sling was required 1.9 times on average. Daily pad usage decreased significantly from 3.42 ± 2.00 to 0.84 ± 1.20 (P <.001), and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score improved (18.65 ± 2.61 to 10.55 ± 6.21, P <.001) without deterioration of voiding symptoms at the last follow-up. MRS was successful in 46 of 64 patients (71.9%). Of the 18 patients who experienced surgical failure, 12 patients required secondary artificial urethral sphincter implantation. The number of daily used pads (odds ratio 1.414) and a history of pelvic irradiation (odds ratio 8.400) were potential risk factors for surgical failure.

CONCLUSION

According to our midterm follow-up data, MRS is an effective and a safe treatment option for radiation-naïve patients with a mild degree of postprostatectomy incontinence.

A transobturator adjustable system for male incontinence: 30-month follow-up of a multicenter study

PURPOSE

To report long-term results of the Argus T adjustable system for treatment of post-prostatectomy urinary incontinence (PPI).

MATERIALS AND METHODS

From October 2007 to August 2008, 37 patients with PPI were included in a prospective, single-arm, multicenter trial of treatment with the Argus T adjustable system (Promedon, Argentina). Preoperative evaluation included urine culture, urethrocystoscopy, urodynamic testing, 24-h pad weight test (PWT) and quality of life questionnaires. Patients were stratified according to baseline degree of incontinence (mild-moderate or severe). Postoperative evaluation included immediate PWT, quality of life questionnaires and daily use of pads at 1, 12 and 30 months.

RESULTS AND CONCLUSIONS

One patient was lost to follow-up. At the 30-month follow-up, 24/31 patients (77%) were dry, 3/31 (10%) improved and 4/31 (13%) were failures. In particular, in the mild-moderate group, 8/8 (100%) patients were dry. In the severe group, 20/28 patients (71%) were dry, 3/28 (11%) improved and 5/28 (18%) were failures. Median visual analogue scale (VAS) scores dropped from 9 (4-10) to 0.5 (0-10) and International Consultation on Incontinence Questionnaire Short Form scores from (ICIQ-SF) 19 (12-21) to 1 (0-10). Retrograde leak point pressure increased from 18 (5-29) to 35 (22-45) cm H2O after intraoperative adjustment. Complications included immediate postoperative infection in 2/36 patients (6%) and transient inguinal and/or perineal pain in 22/36 patients (61%). Argus T has a long-term high success rate (86% cure + improvement at the 30-month follow-up). Good outcomes were achieved even in severe incontinence cases and maintained for over 30 months.

A pragmatic approach to the characterization and effective treatment of male patients with postprostatectomy incontinence

PURPOSE OF REVIEW

To highlight the recent developments in the past 12 months in the field of postprostatectomy incontinence.

RECENT FINDINGS

The evaluation of postprostatectomy incontinence is mainly based on clinical details and symptoms assessment. The situation in which urodynamics will change the management and influence clinical decision-making is still unknown. MRI may play a role in the future for postprostatectomy incontinence assessment. Artificial urinary sphincter is the most widely used treatment, and the literature is full of technical reports to improve the management of challenging cases and minimize the risk of complications. Advance male sling has been the subject of multiple reports that support its safety and efficacy. Many other innovative devices have been presented but not adequately tested.

SUMMARY

Evaluation of postprostatectomy incontinence is based on clinical data, involving symptoms assessment, quality of life, and incontinence severity. Endoscopy is requested, and urodynamic study indications are debated. The treatment is mainly focused on surgical options, of which artificial urinary sphincter and transobturator male slings are the two leaders. The field is critically lacking of comparative studies.

The Artificial Urinary Sphincter is Superior to a Secondary Transobturator Male Sling in Cases of a Primary Sling Failure

PURPOSE

We compared continence outcomes in patients with post-prostatectomy stress urinary incontinence treated with a salvage artificial urinary sphincter vs a secondary transobturator sling.

MATERIALS AND METHODS

We retrospectively reviewed the records of patients undergoing salvage procedures after sling failure from 2006 to 2012. Postoperative success was defined as the use of 0 or 1 pad, a negative stress test and pad weight less than 8 gm per day. We performed the Wilcoxon test and used a Cox regression model and Kaplan-Meier survival analysis.

RESULTS

A total of 61 men presenting with sling failure were included in study, of whom 32 went directly to an artificial urinary sphincter and 29 received a secondary sling. Of the artificial urinary sphincter cohort 47% underwent prior external beam radiation therapy vs 17% of the secondary sling cohort (p = 0.01). Average preoperative 24 hour pad weight and pad number were higher in the artificial urinary sphincter cohort. Median followup in artificial urinary sphincter and secondary sling cases was 4.5 (IQR 4-12) and 4 months (IQR 1-5), respectively. Overall treatment failure was seen in 55% of patients (16 of 29) with a secondary sling vs 6% (2 of 32) with an artificial urinary sphincter (unadjusted HR 7, 95% CI 2-32 and adjusted HR 6, 95% CI 1-31).

CONCLUSION

In this cohort of patients with post-prostatectomy stress urinary incontinence and a failed primary sling those who underwent a secondary sling procedure were up to 6 times more likely to have persistent incontinence vs those who underwent artificial urinary sphincter placement. These data are useful for counseling patients and planning surgery. We currently recommend placement of an artificial urinary sphincter for patients in whom an initial sling has failed.

Surgery for postprostatectomy incontinence: which procedure for which patient?

Surgery remains the most effective treatment for postprostatectomy incontinence. Over the past two decades, this surgery has evolved with respect to both operative technique and sling design, and various devices are now available that have different mechanisms of action, such as the artificial urinary sphincter, retroluminal sling or quadratic sling. The choice of device, however, should be individualized according to the circumstances of each patient. The optimal surgical treatment depends on a variety of patient-related factors, including the degree of urine leakage as assessed by incontinence pad weight test results, bladder contractility, urethral compliance, history of radiation exposure or prior incontinence surgery, and patient preference--given the choice, most patients opt for a sling procedure over an artificial sphincter to avoid implantation of a mechanical device. Athorough urodynamic evaluation is, therefore, necessary for the majority of patients. An artificial urinary sphincter, retroluminal sling or quadratic sling might be the most appropriate choice for a particular patient, depending on their specific urodynamic findings. Progress in this field continues, and several new devices are in development.

Management of urinary incontinence after radical prostatectomy

In the year following a radical prostatectomy, most men recover from any initial urinary incontinence. Nonetheless, incontinence greatly affects a man's quality of life during that time, as it does for those who have persistent incontinence thereafter. Urological assessment should be thorough in order to ensure that no treatable etiology exists aside from stress incontinence. Conservative measures can then be applied from the earliest stages, and offer benefit for those with mild to moderate symptoms. Failing this, a wide variety of surgical options can be considered. For effective outcomes, a clinician must ensure that surgical decision-making is based on current evidence and patient preference, and that it considers possible morbidities.

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.

First experience with the ATOMS(®) implant, a new treatment option for male urinary incontinence

Introduction

Urinary incontinence (UI) is defined as any complaint of involuntary urine leakage. A description is provided of our experience with the ATOMS^® (Adjustable Transobturator Male System. Agency for Medical Innovations. A.M.I.) adjustable implant in patients with mild to moderate UI.

Material and methods

A retrospective study was made of the data referring to 13 patients treated with this adjustable system. Demographic and personal data were collected along with information on the etiology, severity, characteristics, duration of UI, complementary tests, surgery times, complications and results obtained.

Results

The full continence (no use of pad) recovery rate at the close of the study was 12/13 (92.3%). Three cases required a single filling during the mean 16 months of follow–up (range 4–32; median 14 months). A complication in the form of perineal hematoma was resolved with conservative treatment and a case of urinary retention was resolved by placing a bladder catheter for the duration of one week. Three patients experienced perineal–scrotal dysesthesias that disappeared spontaneously in the first three months.

Conclusions

The described adjustable continence system has been found to be very effective in males with mild to moderate UI. In our experience, the ATOMS^® implant offers excellent results over the middle term with a very low rate of complications that were easily resolved in all cases.

Comparing Argus sling and artificial urinary sphincter in patients with moderate post-prostatectomy incontinence

Post-prostatectomy incontinence (PPI) is a main complication of radical prostatectomy. The purpose of this study was to compare the efficacy and safety of the Argus male sling (Argus) with that of artificial urinary sphincters (AUS) in patients with moderate PPI. A total of 33 moderate PPI patients underwent AUS or Argus implantation from January 2009 to June 2013 (13 AUS, 20 Argus). We defined moderate PPI as the use of 2-4 pads per day. To compare efficacy, we assessed the success rate between the two groups. Success was defined as the daily need for no pads or one small safety pad that remained dry most of the day. The mean patient age was 73.5±6.3 yr in the AUS group and 70.9±5.1 yr in the Argus group, and the mean follow-up period was 29.8±14.9 months in the AUS group and 24.7±11.8 months in the Argus group. The success rate was 72.7% in the AUS group and 85.0% in the Argus group (P=0.557). Abnormal postoperative pain persisted in more patients in the Argus group (6/20, 30%) than in the AUS group (1/13, 7.7%) (P=0.126). However, the rate of other complications was not different between the two groups (7.7% and 15.0% for AUS and Argus, respectively, P=0.822). Argus surgery showed similar success and complication rates to those of AUS in moderate PPI patients, indicating that it could be an alternative surgical option for the treatment of moderate PPI.

National study of utilization of male incontinence procedures

AIMS

We explored re-interventions and short and long term adverse events associated with procedures for male incontinence among Medicare beneficiaries.

METHODS

All inpatient and outpatient claims for a simple random sample of Medicare beneficiaries for 2000-2011 were queried to identify patients of interest. All male patients with an International Classification of Diseases, 9th Edition (ICD-9) diagnosis code for stress incontinence or mixed incontinence were included. Artificial urinary sphincter recipients, patients who underwent a sling operation and those receiving an injection of a bulking agent were identified with Current Procedure Terminology (CPT-4) and ICD-9 Procedure Codes.

RESULTS

The entire cohort of 1,246 patients were operated on between 2001 and 2011. 34.9% of them received an artificial urinary sphincter (AUS), 28.7% with a bulking agent, and 36.4% with a sling. There were no statistically significant differences in demographics or comorbidities between the treatment groups, except that more sling patients were obese (P = 0.006) and fewer bulk patients had diabetes (P = 0.007). There are, however, significant changes in procedures selected over time (P < 0.001). In the first year and over the entire follow-up after surgery, patients treated with bulking agents had the most subsequent interventions (40.1% and 52.9%), followed by sling (10.4% and 15.5%), and AUS (2.3% and 20%) (P < 0.001). Post-operative and 90 day complications were low.

CONCLUSIONS

All three treatments seem to be safe among Medicare beneficiaries with multiple comorbidities. The urological, infectious, and neurological complication occurrences were low.

Surgical treatment of neurogenic stress urinary incontinence: A systematic review of quality assessment and surgical outcomes

BACKGROUND

There are many opinions but little firm knowledge about the optimal treatment of neurogenic stress urinary incontinence (NSUI).

OBJECTIVE

To scrutinize the quality and surgical outcomes of the available treatment modalities in the published literature.

EVIDENCE ACQUISITION

A systematic review of the published literature from Pub Med and Web of Science was undertaken for studies describing surgical treatment of NSUI between 1990 and 2013. A checklist of criteria of methodological and reporting quality of interventions in urological publications was applied to assess quality of the retrieved publications. Surgical outcomes of success, failure, and reoperation were calculated. Statistical analyses included one-way ANOVA and post-hoc tests to determine significant differences between groups.

EVIDENCE SYNTHESIS

Thirty studies were identified with Level 3 evidence. The quality of reporting was 43-81%, with significantly higher quality noted in studies published after 2002 (64% vs. 45%, P < 0.0001). None of the studies followed a randomized controlled trial (RCT) design. Three primary surgical procedures were used in 29 of 30 studies: artificial urinary sphincter (AUS), urethral slings, and urethral bulking agents. One study used a ProACT device. AUS was considered more successful than urethral bulking agents (77 ± 15% vs. 27 ± 20%, P = 0.002). Urethral bulking agents reported higher failures than urethral sling procedures (49 ± 16% vs. 21 ± 19%, P = 0.016) and AUS (21 ± 19% vs. 10 ± 11%, P < 0.002).

CONCLUSIONS

The quality of evidence obtained from non-RCTs is modest. Surgeries for NSUI have relatively high success rates but also high complication rates in this highly heterogeneous population. More studies using modern techniques are required to update our knowledge.

Stemming the tide of mild to moderate post-prostatectomy incontinence: A retrospective comparison of transobturator male slings and the artificial urinary sphincter

INTRODUCTION

The AUS remains the gold standard treatment for post-prostatectomy incontinence (PPI), although most patients with mild-moderate PPI prefer a sling without strong evidence of procedural equivalence. This study compares outcomes of 2 procedures for the treatment of mild-moderate PPI.

METHODS

A retrospective review of 124 patients (76 transobturator sling, 48 AUS) with mild-moderate PPI requiring intervention over an 8-year period. The primary outcome was continence. Secondary outcomes included global patient satisfaction, improvement, and complication rates. Mild to moderate incontinence was defined as requiring ≤5 pads/day.

RESULTS

There was no significant difference in age (66.2 vs. 68.1 years; p = 0.17) or prostate cancer characteristics for slings and AUS, respectively. AUS patients had higher Charlson comorbidity scores and were more likely to have previous radiotherapy. Median length of follow up was 24 months for slings and 42 months for AUS. There was no difference in continence rates, 88.2% vs. 87.5% (p = 0.79), rate of improvement, 94.7% vs. 95.8% (p = 1.00), or patient satisfaction, 93.4% vs. 91.7% (p = 0.73), for slings and AUS, respectively. Complication rates were equivalent (19.7% vs. 16.7%; p = 1.00), though a significantly higher proportion of complications with AUS were Clavien Grade 3 (0% vs. 75%; p = 0.006).

CONCLUSIONS

For mild to moderate PPI there is no difference in continence, satisfaction, or improvement rates, between AUS and slings. AUS complications tend to be more severe. Our study supports the use of slings as first-line treatment for mild-moderate PPI.

The virtue sling--a new quadratic sling for postprostatectomy incontinence--results of a multinational clinical trial

OBJECTIVE

To successfully perform male sling surgery, and the surgery must achieve proximal urethral relocation and/or bulbar urethral compression. The Virtue quadratic sling is a novel device that incorporates both mechanisms of action. We report the 1-year results of the Virtue sling with fixation and compare it with the results of the initial "unfixed" sling trial.

METHODS

A prospective trial was performed to assess the efficacy and safety of the Virtue sling. Objective success was predefined as >50% decrease in 24-hour pad weight and subjective success as a score of "much" or "very much" better on the Patient Global Impression of Improvement. Subgroups were analyzed by baseline incontinence: mild (<100 g), moderate (100-400 g), and severe (>400 g). After analysis of the 1-year data, a second clinical trial incorporating a novel "fixation" technique was performed, with similar outcome measures.

RESULTS

In the initial cohort, subjective and objective successes were achieved in 41.9% at 12 months. Median pad weight reduction was 51.1% at 12 months and varied with the degree of baseline leakage. In the fixation cohort, subjective and objective successes were 70.9% and 79.2%, median pad weight reduction was 88.3% at 12 months, and efficacy was similar regardless of baseline incontinence. There were no cases of prolonged retention and no severe adverse events.

CONCLUSION

The Virtue sling with fixation is a safe and efficacious treatment for postprostatectomy incontinence. Superior 12-month results compared with the unfixed device demonstrate that fixation prevents early sling loosening.

Update on management of post-prostatectomy incontinence in 2013

Surgical intervention is often required to address urinary incontinence post-prostatectomy. This summary provides an overview of surgical intervention in post-prostatectomy incontinent patients and of the evidence supporting the various surgical interventions currently in use.

Following the needles: an anatomical study to evaluate the postoperative safety and symptoms of patients receiving a transobturator male sling implant

PURPOSE

Implanting a transobturator male sling is a valid option to manage urinary incontinence after prostatectomy. We evaluated the trajectory of Argus T™ needles blindly introduced into the retropubic space to determine the safety and etiology of postoperative symptoms that can arise from this implant.

MATERIALS AND METHODS

Needles were implanted and perineal dissection was performed in 20 fixed, adult human male cadavers. The distance was measured from the upper and lower extremities of the needles in the internal pelvic wall up to the obturator neurovascular bundle. Anatomical variations identified in this area proximal to the needles were characterized. The inguinocrural region was also dissected from the needles positioned there. Statistical analysis of the results was done.

RESULTS

All needles transfixed the obturator internus muscle. Of the needles 90% were completely immersed in its fibers and not visible in the inner wall of the pelvis. The distance to the obturator neurovascular bundle and anatomical variations were noted. In the inguinocrural region the pectineus and adductor longus muscles were perforated in all cadavers.

CONCLUSIONS

The needle sling implant preserves the obturator neurovascular bundle and obviates the potential for postoperative pelvic hematoma. The anatomical trajectory of the needles used for this implant account for the groin and perineal pain side effects. Based on similarities between the Argus T and other types of outside-in transobturator male slings the results of the current study could be extrapolated to the latter slings.

Autologous retro-pubic urethral sling: a novel, quick, intra-operative technique to improve continence after robotic-assisted radical prostatectomy

After radical prostatectomy, many men may suffer from urinary incontinence, which can have detrimental effects on quality of life. We describe a novel technique using an autologous retro-pubic urethral sling placed at the time of robotic-assisted laparoscopic prostatectomy (RALP) and evaluate its impact on post-operative urinary continence. During 2011, 153 men who underwent sling placement at the time of RALP at a high-volume academic institution were compared to 78 men who did not undergo sling placement. The primary outcomes were time to one and no pads per day. The association between these outcomes and placement of a sling was assessed using Cox proportional hazards regression. Median follow-up was 26 weeks in those who had slings and 32.5 weeks in those who did not. Clinical and pathological characteristics were similar between the groups, with the exception that sling patients were older (p < 0.01) and underwent less nerve sparing (p < 0.01). Multivariate analysis showed that sling placement did not appear to have an effect on time to one (p = 0.24) or no pads per day (p = 0.20). Although the association between sling placement and early return of urinary continence did not reach statistical significance, there was a selection bias against the sling, since it was placed in men who were expected to have more difficulty regaining their continence. A randomized trial is needed to assess the true benefit of sling placement on urinary continence.
