Stress urinary incontinence in the male patient has been successfully treated with the artificial urinary sphincter. However, approximately 15% of the patients treated are still significantly wet despite some improvement with this device. These patients usually are almost totally incontinent before artificial sphincter implantation. Of 15 such patients 80% were rendered satisfactorily dry by adding a second sphincter cuff around the bulbous urethra. This double cuff technique increases the success rate with the AMS800 sphincter to greater than 95%.
