Asynchronous erosion of inflatable penile prosthesis into small and large bowel.

Complications of a 3-piece inflatable penile prosthesis reservoir are rare, with rupture and fluid leakage being the most common. We recently encountered a patient in whom the reservoir migrated twice into the bowel. A review of the literature suggests that a previous major pelvic or abdominal operation might contribute to erosion of the reservoir into the adjacent viscera.
