Long-term results with Hydroflex and Dynaflex penile prostheses: device survival comparison to multicomponent inflatables.

Abstract

We compared our experience with self-contained inflatable and multicomponent prostheses during similar intervals. 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. 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. 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.
