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.
AS791人工括约肌被植入66例前列腺癌根治术后尿失禁患者体内。这些患者中，49例（74%）在植入后3个月至4年半保持控尿。排除22例曾接受盆腔放疗的患者后，41例（93%）保持控尿。机械问题很少，证明了这种独特括约肌机制的可靠性。
