Mechanical failure with malleable penile prosthesis.

Mechanical failure with a malleable penile prosthesis is very rare, and no mechanical failure has been reported with the AMS 650 malleable penile prosthesis. A 67-year-old man, using the AMS 650 malleable penile prosthesis without a problem since 1999, presented with right penile deformity and difficulty in sexual intercourse for the preceding 2 months. Physical examination showed dislocation of the right rod of the penile prosthesis, and surgical exploration revealed a fracture in the rod. The malfunctioning right penile prosthesis was removed, and a new AMS 650 malleable penile prosthesis was implanted. The patient did not have any problem at 1-year follow-up.
