We investigated whether the AMS Ultrex cylinder, developed to provide cylinder lengthening while controlling girth expansion, acted as a tissue expander and, thus, promoted penile lengthening.
Between December 1990 and January 1992, 59 AMS Ultrex prostheses were implanted. Cylinder length corresponded to intracorporeal measurements. The results of lengthening and occurrence of an S-shaped deformity were statistically analyzed.
No penile lengthening occurred. In 19 patients (32%) cylinder replacement was required for the S-shaped deformity.
Ultrex cylinders should be downsized and prolonged inflation should be avoided. They should not be implanted in cases of Peyronie's disease, or to replace malleable or self-contained inflatable implants.
我们研究了旨在在控制周长扩张的同时实现圆柱体延长的AMS Ultrex圆柱体是否起到组织扩张器的作用，从而促进阴茎延长。
1990年12月至1992年1月期间，植入了59个AMS Ultrex假体。圆柱体长度与体内测量值相对应。对延长结果和S形畸形的发生情况进行了统计分析。
未出现阴茎延长。19例患者（32%）因S形畸形需要更换圆柱体。
应减小Ultrex圆柱体的尺寸并避免长时间充气。佩罗尼氏病患者或用于替换可弯曲或自含式可充气植入物的情况下不应植入。
