Surgical success with AMS M800 GU sphincter for male incontinence

Forty-two incontinent males were treated with the surgical implantation of the AMS M800 GU sphincter from 1982 to 1987. Patients' ages ranged from twenty-four to eighty-four years. All patients had the M800 GU sphincter deactivated from six to sixteen weeks post implantation. Patients were followed from seven to sixty months postoperatively with a mean follow-up of 26.2 months. Thirty-two males (76%) were completely continent post insertion of the M800 GU sphincter while 4 men (9%) experienced minimal to moderate stress incontinence. Two patients (5%) were unable to manipulate the device secondary to physical and/or mental incapacity. Four patients (9%) required removal of components or the entire GU sphincter secondary to infection and/or erosion. Two of these men were subsequently reimplanted with the M800 sphincter and are now totally continent.
