Recent advances in the diagnosis and management of impotence.

Recent experience with the implantation of the OmniPhase, FlexiFlate, and Hydroflex penile prostheses at our institution has shown all three to provide good axial rigidity and relatively good concealment, although the phallus tends to be much more expanded than normal with all three devices when they are in the nonfunctional position. Urologists who are familiar with penile implantation surgery will encounter no technical difficulties with the implantation of these new devices. Rather, long-term mechanical reliability will be the crucial factor that will cause implanting surgeons and their patients to shift from one prosthesis to another.
