Mid-term Outcome After Bulbourethral Composite Suspension for Postprostatectomy Incontinence

Male Slings for Postprostatectomy Incontinence: A Systematic Review and Meta-analysis

CONTEXT

Male slings are recommended by the European Association of Urology guideline for the treatment of mild to moderate postprostatectomy incontinence. However, none of them has been proved to be superior to the others, and there are no defined guidelines to preference of a given sling model.

OBJECTIVE

To evaluate and compare the efficacy and safety of the different types of male slings in the treatment of postprostatectomy incontinence.

EVIDENCE ACQUISITION

This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. A systematic literature search in the databases of PubMed, Embase, and Cochrane using the keywords "incontinence," "prostatectomy," and "male sling/system" was conducted in June 2018. Studies in English with at least 15 patients and a minimum follow-up of 12 mo were included. As the primary endpoint, we assessed the cure rate of the different sling types. As secondary endpoints, we assessed the improvement rate, subjective cure rate, overall complication rate, explantation rate, risk factors for failure, and effect on patients' quality of life.

EVIDENCE SYNTHESIS

The literature search identified 833 articles. A total of 64 studies with 72 patient cohorts were eligible for inclusion. Fixed slings were implanted in 55 (76.4%) of the patient cohorts. The objective cure rate varies between 8.3% and 87% (pooled estimate 0.50, 95% confidence interval [CI] 0.45-0.56, I²=82%). Subjective cure was achieved in 33-94.4%. Adjustable slings showed objective cure rates between 17% and 92% (pooled estimate 0.61, 95% CI 0.51-0.71, I²=88%). The subjective cure rate varies between 28% and 100%. In both types of slings, pain was the most common complication, but chronic painful conditions were really rare (1.3% in fixed slings and 1.5% in adjustable slings). The most common complication after pain was urinary retention in fixed slings, and infection and consequential explantation in adjustable slings.

CONCLUSIONS

Both fixed and adjustable slings are beneficial for the treatment of postprostatectomy incontinence. Although adjustable slings might lead to higher objective cure rates, they might be associated with higher complication and explantation rates. However, at present, due to significant heterogeneity of the data, this cannot be said with certainty. More randomized controlled trials with long-term follow-up and the same definition for continence are needed.

PATIENT SUMMARY

Fixed and adjustable slings are effective treatment options in mild to moderate postprostatectomy incontinence.

Slings in the management of male stress urinary incontinence

PURPOSE OF REVIEW

The use of synthetic slings for the treatment of male stress urinary incontinence (SUI) has increased over the last decade. Several sling designs and techniques are now available. The purpose of this review is to summarize the past literature with a focus on more recent contributions.

RECENT FINDINGS

The recent literature focusses on the retrourethral transobturator sling (RTS), which is considered noncompressive. MRI of patients undergoing RTS has shown an increase in membranous urethral length and elevation of the external urethral sphincter, whereas a recent large series demonstrated approximately a half and a quarter of patients are cured or improved, respectively, at 1 year after RTS implantation, with results sustained through to 3 years. Serious complications such as urethral erosion occur rarely.

SUMMARY

The available evidence suggests that male slings can be an efficacious and well tolerated treatment modality for men with SUI. Nevertheless, important questions remain with regard to the durability of repair, device safety and comparative efficacy. The mechanism of action and factors that predict failure remain to be fully elucidated.

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

OBJECTIVE

To examine the outcomes and adverse events associated with novel male sling designs described in the last decade.

METHODS

A literature review was carried out using Medline, EmBase, Cochrane Registered Trials Database and the Center for Reviews and Dissemination Database.

RESULTS

Three principal slings are described in the literature. The bone-anchored sling has success rates of 40-88%, with some series having a mean follow-up of 36-48 months. It is associated with a mesh infection rate of 2-12%, which usually requires sling explantation. The retrourethral transobturator sling has a success rate of 76-91% among three large case series with follow-ups of 12-27 months. There is a low reported explantation rate. The adjustable retropubic sling has a success rate of 72-79% with follow-ups of 26-45 months. Erosion (3-13%) and infection (3-11%) can lead to explantation.

CONCLUSIONS

Most male slings have a similar reported efficacy. Most case series define success as either dry or improved. True cure rates are lower. Mid- and long-term data are now available that indicate the male sling is a viable option for PPI. The use of male slings in severe UI, radiated patients, and non-radical prostatectomy patients is still unclear. Further study is needed to try and define criteria for the use of male slings, and to directly compare different procedures.

Are male slings for post-prostatectomy incontinence a valid option?

PURPOSE OF REVIEW

Stress incontinence in men is still a common problem after surgical treatment of prostatic disease. This article reviews the techniques and results of recently described surgical slings available to treat male stress incontinence.

RECENT FINDINGS

Medium-term follow-up (mean 3-4 years) of patients treated with bone-anchored slings has been recently published, suggesting a success rate (cured or improved) of 70-80%. Short-term follow-up (mean of 6-12 months) of transobturator retrourethral slings demonstrates a success rate of 62-83%. Novel sling designs include mechanisms to manipulate the tension postoperatively and inside-out transobturator trocar passage. Common complications associated with slings are acute urinary retention and perineal pain. Rare complications include urethral erosion and infection. Retropubic approaches are associated with a risk of bladder perforation.

SUMMARY

Male slings are a valid option for treating male stress incontinence, and do offer several advantages over the artificial urinary sphincter. However, long-term data and multicenter series are needed in order to compare directly with the artificial urinary sphincter.

Underestimated risk of bleeding after male transobturator sling procedure caused by early re-uptake of anticoagulation

The management of postoperative male stress urinary incontinence (SUI) is changing rapidly as greater emphasis on minimizing invasiveness and reducing complications leads to technical innovations. Various studies have reported comparable continence but lower complication rates for male urethral slings than those observed with artificial urinary sphincters. For this reason, the transobturator sling procedure has been considered a safe and effective treatment option in male SUI patients. In this case study we report severe bleeding with a large hematoma that required transfusion after implantation of an AdVance® male transobturator polypropylene sling in an early re-anticoagulated patient.

Efficacy of the bulbourethral autologous sling in treating male stress urinary incontinence: a three-year experience from a single center

AIM

To evaluate the efficacy of the bulbourethral rectus autologous sling in treating male stress urinary incontinence.

PATIENTS AND METHODS

We retrospectively reviewed operative logs from a single surgeon of 32 male patients treated over a 3-year period (March 2001 to March 2004) for stress incontinence by implantation of a bulbourethral free rectus sling. The mean age of the patients was 46.4 (range 14-76); mean follow-up time was 29.5 months (range 24-52). Neurogenic dysfunction was the most common cause of incontinence in this group (17/32 cases; 53.1%). Efficacy was evaluated objectively in terms of the number of pads used per day, subjective patient satisfaction, and morbidity. We also investigated a possible correlation between pre-operative parameters and outcome.

RESULTS

Ten patients (31.3%) were cured (totally dry, 15.6%; the remainder one pad per day), while five (15.6%) patients improved but still required two pads per day. Overall, 15 of 32 patients (46.9%) were satisfied with the outcome of the operation. In total, seven patients presented a mild complication (21.9%). De novo urgency was the most common complication presented in four of 32(11.6%). No case of urethral erosion was encountered. Univariate analysis failed to find any correlation between the final outcome and the following parameters: patient age, duration of incontinence, earlier anti-incontinence surgery, severity of pre-operative incontinence, pre-operative Valsalva leak point pressure, decreased compliance, decreased bladder capacity, and pre-operative evidence of detrusor overactivity.

CONCLUSIONS

In conclusion, the free rectus fascia bulbourethral sling is a modestly effective technique for the treatment of male stress incontinence with mild morbidity. The use of this method seems that it is suitable for selected cases.
