Between February, 1981, and September, 1990, 444 men with erectile dysfunction were implanted with AMS inflatable penile prostheses. Etiology was vascular for 62% and diabetic for 22%. Ninety-three percent had a functional prosthesis at last contact. Overall, 74% of the originally-implanted cylinders were functional at last contact with no revisions; an additional 3% required one or more revisions, though no replacement, to maintain function. Of the sub-group receiving PPS cylinders as the first implant under my care, 35% have required no revision; along with 66% implanted with the thicker-walled PPT; 85% with the PND, designed to reduce stress on the tunica albuginea and prevent aneurysm formation; and 90% with the CX cylinders. This greatly improved reliability can be ascribed to (1) continued improvements by the manufacturer, (2) use of a single prosthesis type leading to improved surgical proficiency, and (3) a modified revision technique when a fluid leak has occurred, making it frequently unnecessary to replace the entire device.
在1981年2月至1990年9月期间，444例勃起功能障碍男性接受了美国医疗系统公司（AMS）可膨胀阴茎假体植入。病因中血管性的占62%，糖尿病性的占22%。在最后一次随访时，93%的患者假体功能良好。总体而言，最初植入的圆柱体在最后一次随访时74%功能良好且无需翻修；另有3%虽无需更换但需要一次或多次翻修以维持功能。在我负责的首次植入PPS圆柱体的亚组中，35%无需翻修；首次植入厚壁PPT圆柱体的患者中这一比例为66%；首次植入旨在减轻白膜压力并预防动脉瘤形成的PND圆柱体的患者中这一比例为85%；首次植入CX圆柱体的患者中这一比例为90%。可靠性的大幅提高可归因于：（1）制造商的持续改进；（2）使用单一类型的假体提高了手术熟练程度；（3）出现液体泄漏时采用改良的翻修技术，使得常常无需更换整个装置。
