Erosion of inflatable penile prosthesis reservoir into bladder.

We report a case of erosion of an inflatable penile prosthesis reservoir into the bladder, which evidently occurred during a revision procedure for replacement of a defective pump. There was a significant delay between the time of failure of the prosthesis and the time of revision. Inflatable penile prostheses should be repaired as soon as possible after discovery of leakage.
