[Urinary incontinence. Indications and results of hydraulic sphincter prosthesis].

An AMS 800 sphincteral prosthesis was implanted in 20 patients (18 men and 2 women) with total urinary incontinence, with results that were superior to those of the previously used procedures: success in 18 cases (90%), failure in 2 cases (1 incontinence, 1 explantation). A change of material was necessary in 3 patients. The AMS 800 prosthesis constitutes a major advance in the treatment of iatrogenic (post-prostatectomy) incontinence in man, of recurrent stress incontinence in women and of some cases of neurogenic or malformative urinary incontinence.
