The investigators propose a randomized non-blinded comparison of standard vs. transcorporal approach for placement of an artificial urinary sphincter in male patients with stress urinary incontinence after radiation and radical prostatectomy for prostate cancer. In the United States, the artificial urinary sphincter (AUS), manufactured by American Medical Systems, is the gold standard surgical treatment for stress urinary incontinence (SUI) in men. The cuff, which is the portion of the device that encircles and occludes the urethra, is typically placed directly around the urethra (i.e., "standard" placement). The cuff can erode into the urethra. Transcorporal placement has been introduced as a method to reduce the risk of erosion. Transcorporal placement involves tunneling the cuff through the erectile bodies so as to protect the dorsal aspect of the urethra. This approach has never been compared to standard placement in a randomized fashion. In the randomized trial, no additional procedures beyond the normal care protocol will be required of the patients. The investigators will conduct the study through an established, IRB-approved multi-institutional network of surgeons. Success will be assessed via objective and subjective methods; complications will be tallied in a standardized fashion. Outcomes will be measured at two years.
