Mentor inflatable penile prosthesis: clinical experience in 52 patients.

The Mentor inflatable penile prosthesis is manufactured from Bioflex polyurethane, a material which is less elastic and more durable than silicone. Use of this new biocompatible polymer eliminates cylinder aneurysms and wear-induced cylinder leaks. The new prosthesis also incorporates a snap-on connector system designed to eliminate connector leaks and decrease operative time. The Mentor prosthesis has been implanted in 52 patients with organic impotence. The patients have been followed up for 2 to 16 months (average 8.3), the follow-up exceeding 1 year in 15 patients. A satisfactory cosmetic and functional result was achieved in 51 cases. Infection necessitated removal of the prosthesis in one patient. There were no pump, reservoir or tubing failures. After early connector failures there were no connector failures in the subsequent 48 patients. Additional complications included an incisional hernia and a cylinder failure which resulted from a manufacturing defect. There were no failures attributable to wear or material fatigue. The inherent reliability of this new prosthesis and the excellent functional and cosmetic results it produces justify its use in any patient who is a candidate for a penile prosthesis.
