The severity of preoperative in- continence correlated with the outcome of the operation, with mild incontinence giving better results. Conclusions: The bone-anchored male sling is an effective and minimally invasive treatment for mild-to-moderate male urinary incon- tinence. Copyright © 2010 S. Karger AG, Basel Introduction Male stress urinary incontinence (SUI) is a potential complication of prostate surgery. Radical prostatectomy is the most common intervention to provoke sphincter insufficiency while prostatic adenomectomy and trans- urethral resection of the prostate are less common causes of incontinence. Even less commonly, SUI may be caused by other neurological conditions or by traumatic injury. Interestingly, SUI often improves over 6–12 months fol- lowing surgery and regardless of the severity of the incon- tinence [1]. Treatment options include collagen injection, implan- tation of an artificial urinary sphincter (AUS), and sur- gical male sling placement. The injection of collagen is a frequent intervention in patients with mild intrinsic Key Words InVance TM bulbourethral sling ? Male stress urinary incontinence ? Prostheses and implants ? Radical retropubic prostatectomy Abstract Introduction: The aim of this study was to evaluate the ef- ficacy of the InVance TM male sling in treating stress urinary incontinence. Patients and Methods: We retrospectively re- viewed operative logs from a single surgeon of 43 patients treated over a 3-year period (Feb. 2004 to Nov. 2006) for stress incontinence by implantation of a male bulbourethral bone-anchoring sling (InVance TM ). The mean follow-up time was 24.2 months (range 4–38). Radical prostatectomy was the most common cause of incontinence in this group (33/ 43 cases; 76.7%). Efficacy was evaluated objectively in terms of the number of pads used per day, while subjective patient satisfaction was also recorded. We also investigated a pos- sible correlation between preoperative parameters and out- come. Results: Twenty-two patients (51.2%) were cured (to- tally dry: 30.2%; the remainder: 1 pad per day), while 8 (18.6%) patients improved but still required two pads per day. Over- all, 30 of 43 patients (69.6%) were satisfied with the outcome of the operation.
