81-year-old male that suffers from mixed incontinence with a prominent component of stress incontinence, following a transurethral procedure. Initially attempts were made to gain continence by a Lenzi's procedure, electro stimulation and various anticholinergis. All in all without satisfactory response. He underwent implantation of an artificial sphincter, the AMS AS 800 (AUS) that provided continence and the patient was content with the end result. The AUS was functioning fine until the patient underwent a road accident trauma, then a sphinteric prosthesis malfunction occurred.
