Abstract
PURPOSE: 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. MATERIALS AND METHODS: 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. RESULTS: No penile lengthening occurred. In 19 patients (32%) cylinder replacement was required for the S-shaped deformity. CONCLUSIONS: 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.
