The artificial urinary sphincter (model AS 791-792), American Medical Systems, Minnetonka, Minn.) has been implanted in 41 patients (mean age 13.9 years) who were incontinent in spite of intensive efforts with other modes of management. Neurogenic bladder dysfunction is present in 34 patients. Seven patients have non-neuropathic dysfunction of the bladder neck and urethra (3 with exstrophy/epispadias, 3 incontinent after multiple bladder and urethral procedures, and 1 incontinent after a pelvic fracture). Twenty-two patients have had intestinocystoplasty performed and 11 patients had previous urinary diversion. Mean follow-up for a given device is 23 months (range 6 to 47 months). Of these patients, 80.5% are totally or acceptably dry. Five patients (12.2%) were rated as fair, and three were failures (7.3%). Complications have been significant in that reoperation has been necessary in 16 patients. Indications for patient selection is emphasized.
人工尿道括约肌（AS 791 - 792型号），美国美敦力公司，明尼苏达州明尼通卡）已植入41例患者体内（平均年龄13.9岁），这些患者尽管采用了其他强化治疗方法仍存在尿失禁问题。34例患者存在神经源性膀胱功能障碍。7例患者患有膀胱颈和尿道的非神经源性功能障碍（3例患有膀胱外翻/尿道上裂，3例在多次膀胱和尿道手术后出现尿失禁，1例在骨盆骨折后出现尿失禁）。22例患者接受了肠膀胱扩大术，11例患者之前进行过尿流改道。给定装置的平均随访时间为23个月（范围6至47个月）。在这些患者中，80.5%完全或可接受地保持干爽。5例患者（12.2%）被评为尚可，3例为失败（7.3%）。并发症较为严重，16例患者需要再次手术。强调了患者选择的适应症。
