An Artificial Urinary Sphincter (AUS) is a device that has a cuff that goes around the urethra, a pump in the scrotum, and a balloon in the abdomen. The cuff is closed most of the time, preventing leakage. When the patient cycles the device, using the pump in the scrotum, the cuff opens up and allows the patient to urinate. Over a minute or so, the cuff refills with fluid, thus causing continence again. The devices are typically put in either through a very small incision on the upper part of the scrotum or with two incisions (one in the perineum (the area between the scrotum and anus) and one in the groin or abdomen).
