[Treatment of erectile dysfunction with a penile prosthesis]

From 1973 to February 1989 a total of 309 patients with erectile dysfunction were treated with hydraulic penile prostheses. In 169 patients a hydraulic prosthesis type AMSIPP700 was implanted; with this prosthesis the primary success rate was 91.1%. As a result of technical improvements to the device the revision rate, initially 52.3% has fallen to 3.3%. Patient acceptance is better with hydraulic prostheses, which provide optimal simulation of the physiological processes of erection and detumescence, than with any other type of prosthesis.
