Radical Prostatectomy Incontinence and the AS791 Artificial Urinary Sphincter

Abstract

The AS791 prosthetic sphincter was implanted in 66 patients with urinary incontinence after radical prostatectomy. Of these patients 49 (74 per cent) were continent 3 months to 4 1/2 years after implantation. Excluding the 22 patients who had had previous pelvic radiation therapy 41 (93 per cent) were continent. Mechanical problems have been few, establishing the reliability of this unique sphincter mechanism.
