Long-term Results with Hydroflex and Dynaflex Penile Prostheses: Device Survival Comparison to Multicomponent Inflatables

Abstract

PURPOSE: We compared our experience with self-contained inflatable and multicomponent prostheses during similar intervals. MATERIALS AND METHODS: We followed 295 patients with self-contained prostheses and 1,026 with multicomponent inflatable devices for up to 8 years. Revision rates for mechanical failure, infection or patient dissatisfaction were statistically analyzed. RESULTS: Multicomponent inflatable prostheses were superior with regard to mechanical reliability and patient satisfaction, with no differences in rate of infection. Self-contained prostheses were best replaced with the AMS 700CX device, thus avoiding aneurysm. CONCLUSIONS: Self-contained inflatable prostheses may be of limited value for the treatment of impotence. The AMS 700CX is the device of choice for replacement of explanted self-contained prostheses.
