Surgical approaches for penile prosthesis implantation: penoscrotal vs infrapubic.

Surgical approaches for implantation of three-piece inflatable penile prostheses include the infrapubic and the penoscrotal. The penoscrotal approach avoids possible injury to the dorsal sensory nerves, provides easier and more complete corporeal exposure, and allows the pump to be anchored in the scrotal pouch. A variant of the penoscrotal approach, the transverse penoscrotal incision, is described.
