[Male stress urinary incontinence by InVance bone anchored sub-urethral sling: Predictive factors of treatment failure: Multicentric study by the CTMH-AFU]

Narrative review of male urethral sling for post-prostatectomy stress incontinence: sling type, patient selection, and clinical applications

Male stress urinary incontinence (SUI) following prostate treatment is a devastating complaint for many patients. While the artificial urinary sphincter is the gold standard treatment for male SUI, the urethral sling is also popular due to ease of placement, lack of mechanical complexity, and absence of manual dexterity requirement. A literature review was performed of male urethral sling articles spanning the last zz20 years using the PubMed search engine. Clinical practice guidelines were also reviewed for comparison. Four categories of male urethral sling were evaluated: the transobturator AdVance and AdVance XP, the bone-anchored InVance, the quadratic Virtue, and the adjustable sling series. Well selected patients with mild to moderate urinary incontinence and no prior history of radiation experienced the highest success rates at long-term follow up. Patients with post-prostatectomy climacturia also reported improvement in leakage after sling. Concurrent penile prosthesis and sling techniques were reviewed, with favorable short-term outcomes demonstrated. Male urethral sling is a user-friendly surgical procedure with durable long-term outcomes in carefully selected men with mild stress urinary incontinence. Multiple sling types are available with varying degrees of efficacy and complication rates. Longer follow-up and larger cohort sizes are needed for treatment of newer indications such as climacturia as well as techniques involving dual placement of sling and penile prosthesis.

[Multicenter study of Advance ® suburethral sling for treatment of postoperative urinary incontinence of male]

OBJECTIVES

To estimate in the medium term, the efficiency and morbidity of Advance(®) for the treatment of postoperative urinary incontinence for male, and determine predictive preoperative factors of success or failure.

MATERIAL AND METHODS

Retrospective multicentric clinical study of patients presenting a postoperative urinary incontinence and treated by Advance(®) suburethral sling. The importance of the preoperative incontinence was classified in three groups: light (pad-test<50 g/day or 1 pad/day), moderated (pad-test between 50 and 100 g/day or 2 or 3 pads/day), severe (pad-test>100 g/day or >3 pads/day). The functional results were classified in 4 categories: continence and improvement, defining the criterion of success and unchanged situation and deteriorated situation defining the criterion of failure.

RESULTS

Sixty-six patients were included from 2008 till 2013. The radical prostatectomy was responsible in 85.5% of the cases. The incontinence was light, moderated and severe for respectively 43.4%, 35.6% and 21% of the patients. After treatment, 39.4% of the patients were continent and 78.9% in situation of success. The rate of success decreased with the severity of the incontinence (respectively 94%, 74% and 56%). For 9 patients, implantation of artificial urinary sphincter was performed without operative difficulties. Complications were urine retention (n=4), hematoma (n=3) and scrotal pains persistent more than one postoperative month (n=11).

CONCLUSION

Advance(®) suburethral sling is a technique in which the efficiency decreases with the severity of the incontinence, but which does not seem to prevent from implanting artificial urinary sphincter. Its main problem is the apparition of scrotal pain.

The two-year outcome of the I-Stop TOMS™ transobturator sling in the treatment of male stress urinary incontinence in a single centre and prediction of outcome

PURPOSE

The aim of this study was to present the results of the 2 year outcome of I-Stop TOMS™ transobturator sling for post-prostatectomy (UIPP) minor to moderate male urinary incontinence treatment.

MATERIALS AND METHODS

A prospective, single center study, including 26 patients with minor to moderate IUPP and operated on using a suburethral sling (MS) TOMS™ (four arms) was performed. UIPP assessment was made preoperatively and 1 year postoperatively, using validated questionnaires (SF36 and ICIQ), number of pads daily, and the 24 hours Pad-test (LPT). Telephone follow-up evaluation was performed in 21 patients over a 2 years period following surgery.

RESULTS

Radical prostatectomy was performed 48.4 months earlier and average patient age was 67.3 years. Preoperatively, the mean number of pads used daily was 2.3 with an average weight loss of 207.1grams at LPT. At 1 year, ICIQ and SF36 scores significantly improved. Weight loss in the LPT as well as the number of pads significantly decreased (P<0.05). At 1 year, 13 patients were cured, 12 were improved, one reached improvement criteria, and 96.2% using a pad daily maximum. With more than a 2 year follow-up, 10/21 patients were dry, nine improved and two failed, and 90.5% using 0 to 1 pad per day.

CONCLUSIONS

The transobturator TOMS™ male sling is a simple and well-tolerated procedure permitting a significant improvement of UIPP, with 50% of patients achieving complete continence at 1 year postoperatively, these good results continued beyond 2 years.

The role of synthetic slings in male stress incontinence

Objective

Our primary aim was to compare the outcomes of synthetic bone-anchored male slings (BAMS) and transobturator male slings (TOMS), to identify preoperative risk factors for failure, and to evaluate patient satisfaction with each procedure.

Patients and methods

Charts were reviewed retrospectively of patients who underwent synthetic BAMS or TOMS from 2000 to 2011. Data were categorised into groups based on outcomes of ‘dry’, ‘improved’ and ‘failure’. Success was defined as completely dry or an improvement by >50% in daily pad use. The data analysed included demographics, daily pad use before and after surgery, previous urethral insult, type of prostatectomy, and urodynamic study variables. Data were analysed using logistical regression, the t-test and chi-square analysis, where appropriate.

Results

Sixty-eight men were analysed (30 in each group; eight patients were excluded). Daily pad use for the TOMS group changed from 3.5 before to 1.5 after surgery (P = 0.001), whilst the BAMS group was unchanged from 3.9 to 3.5 (P = 0.747). The TOMS group had a success rate of 23/30 (77%) and a mean (SD) patient global impression of improvement score of 1.67 (0.90), whilst the BAMS group had a success rate of 11/30 (37%) and mean (SD) score of 2.64 (1.12). Urethral insult (P = 0.001) and preoperative pad use (P = 0.047) were significant predictors of failure.

Conclusion

TOMS gave better outcomes than BAMS in both performance and patient satisfaction. Patients with a greater severity of incontinence and evidence of urethral insult before surgery should be counselled about the likelihood of suboptimal outcomes with any type of sling placement.

Risk factors for male slings: a comparative study of two techniques

OBJECTIVE

To improve patient selection for male slings. Our primary aim was to identify preoperative risk factors for failures. Our secondary aim was to compare bone-anchored male sling (BAMS) to transobturator male sling (TOMS) and patient satisfaction accordingly.

METHODS

A retrospective review was performed from 2000 to 2010 of males who received male slings. Exclusions had follow-up<1.5 months. Data examined included demographics, urodynamic parameters, pad usage, presence of detrusor overactivity (DO), and previous urethral diseases. Failure was defined as ≥4 pads used per day or ≤50% improvement by Patient Global Impression of Improvement (PGI-I). Preoperative risk factors for failure were analyzed for statistical significance.

RESULTS

Sixty-four patients (mean age, 69.8±9.2 years) were analyzed. Forty-one received BAMS and 23 received TOMS with median follow-up of 46 months (range, 1.5-112) and 18 months (range, 3-33), respectively (P=.01). Perioperative decrease in pad usage was statistically significant in the TOMS group (range, 4.0-1.8, P=.00) compared with the BAMS group (range, 4.3-3.9, P=.37). Failure rate was 68.3% (28/41) in BAMS and 30.4% (7/23) in TOMS (P=.01). The PGI-I demonstrated increased satisfaction with TOMS (P=.005). Preoperative risk factors suggest increased pad usage, low maximal urethral closure pressure (MUP), low abdominal leak point pressure (ALPP), decreased functional length (FL), and presence of DO and urethral disease favor failure.

CONCLUSIONS

Patients with preoperative risk factors, such as increased pad usage, low MUP, low ALPP, decreased FL, and presence of DO and urethral disease may not be appropriate sling candidates. Findings support TOMS, whichhas fewer failures and higher patient satisfaction but may be secondary to improved patient selection.

[Male stress urinary incontinence: medium-term results of treatment by sub-urethral bone anchored sling InVance™]

OBJECTIVE

To analyze the functional and urodynamic results of a compressive sub-urethral sling with bone anchoring InVance™.

METHODS

One hundred and six successive patients were operated with this system between August 2004 and March 2009. Urinary incontinence was classified according to the number of daily protections. All the patients have benefited from a clinical, endoscopic and urodynamic pre and post-operative evaluation. The results were classified in four groups, at three months and at one year, according to whether the patients were dry (A), very improved (B), little improved (C), or with no improvement (D).

RESULTS

The average age of the patients during the installation of the strip was 67.4 years (46-82). At three months, the rate of dry (A) or very improved patients (B) was of 81.2% (A=75.5%; B=5.7%), and at one year: 75.5% (A=61%; B=14.5%). At three months, the rate of patients little improved (C) or not improved (D) was of 18.8% (C=16%; D=2.8%), and at one year: 24.5% (C=20.3%; D=4.2%). These results deteriorated according to the initial rank of incontinence II, III, and I. Six patients (5.7%) were explanted because of a prosthetic infection which perished at an average of 9 months (3-18). Infection was linked to operative time (p=0.02), and patients age. No osteitis nor urethral erosion were noted. There was a significant rise in the pressures of maximum fence at rest and maximum urethral pressures in reserve (p=0.01). At one year, score ICIQ-UI SF decreased overall by 7.1 points.

CONCLUSION

The medium-term results of under-urethral supporting with bone anchoring InVance™ are very encouraging. This technique presents an acceptable morbidity and a good tolerance. It can be proposed in first intention for a urinary incontinence whatever the rank is, even if the effectiveness is particularly present in incontinences of rank I and II.

[Functional results and complications of artificial urinary sphincter AMS 800: About 84 cases]

PURPOSE

To verify the effectiveness and safetiness of artificial urinary sphincter (SUA) AMS 800™ in the management of urinary incontinence by sphincter incompetence.

PATIENTS AND METHODS

Retrospective study of patients who received SUA by the same operator between 1992 and 2006. Fifty-seven men and 27 women whose average age was 61 years (22-82) suffered from incontinence by sphincter incompetence: after radical prostatectomy (46%), primary stress or mixed incontinence (21.4%), transurethral resection of prostate (9.5%), injury and neurological malformations (9.5%), pelvic or urethral trauma (7.1%), rectal surgery (3.6%), adenomectomy (2.4%). Functional assessment was made by telephone based on a 23-item questionnaire (Appendix 2).

RESULTS

The mean follow-up was 52.6 months (5.3-187.1): 64% had their original SUA, 50 re-interventions were necessary for 30 patients with 13.1% mechanical complications, 6.6% urethral atrophy, and 13.9% infectious complications, 2.5% failures and 9% definitive explant. The half-time survival without revision was 8.3 years. Sixty-seven percent of patients were contacted for the functional assessment: 77% success rate (≤1 protection), 85% of patients improved, 87% satisfied or very satisfied and 94% would go again through the same operation.

CONCLUSION

The artificial urinary sphincter AMS 800™ remains still the reference in the management of urinary incontinence by sphincter incompetence in improving the quality of life of patients implanted at the cost of a significant revision rate and frequent residual leaks.

[Radiotherapy influence, about results of the InVance(®) male sling in men with stress urinary incontinence]

AIMS

To study impact of previous radiotherapy on urodynamic parameters, continence and complication rate, after prosthetic implantation with InVance® device.

PATIENTS AND METHODS

We included 106 patients between August 2004 and March 2009. We stratified urinary incontinence according to pads daily used, in grade I (one to two pads), II (three to four), or III (more than four or condom catheter use). We compared one group of 24 patients with previous radiotherapy (R) to 82 control patients (T) without one. Follow-up was made at three and six postoperative months and then annually. Results were classified into: no leaks, improved or failure.

RESULTS

Mean follow-up was 14.8 months (median=12.8) in group R and 12.4 months (median=8.8) in group T. At three postoperative months, continence was achieved in 62.5% patients from group R and in 77% patients in group T (P: ns). At 12 months, results on continence were respectively 52.6% in group R and 63.2% in group T (P: ns). Six patients were explanted because of an infection (5.7%), among which two in group R (8.3%) and four in group T (4.8%). Infection was significantly linked to operative time (P: 0.02).

CONCLUSION

Previous radiotherapy has no impact on urodynamic parameters and continence, on short- and mid-term analysis, after implantation of a bone-anchored suburethral sling with InVance® device, preferentially patients with mild to moderate incontinenec urinary.
