Management of Preexisting Inflatable Penile Prosthesis During Radical Retropubic Prostatectomy

A potentially difficult technical situation exists when a man with a functioning inflatable penile prosthesis elects radical prostatectomy as treatment for localized prostate cancer. Between February 1988 and June 1991 we encountered 8 men with a preexisting inflatable penile prosthesis who subsequently underwent radical retropubic prostatectomy. In 2 patients the reservoir portion of the prosthesis was in the perivesical space such that radical prostatectomy could be performed without difficulty. However, in 6 patients removal of the reservoir was necessary to complete the prostatectomy. In 3 of these 6 patients the reservoir was replaced at 3 to 6 months after radical prostatectomy and all 3 systems function well. The remaining 3 patients have not yet elected replacement of the reservoir. Only 1 patient had an infection and a complication attributable to the prosthesis. We believe that a preexisting inflatable penile prosthesis should not preclude successful radical retropubic prostatectomy, although temporary removal of the reservoir may be required.
