008 Submuscular Ectopic Inflatable Penile Prosthesis Reservoir Placement: A Cadaveric Study of Anatomic Location

Abstract

Ectopic submuscular placement of the inflatable penile prosthesis (IPP) reservoir via the inguinal canal has become popularized as an alternative to the traditional retropubic space of Retzius. Published results suggest minimal complications and high patient satisfaction. However, in our practice, we identified several patients presenting for IPP revision after submuscular ectopic placement who were found to have reservoirs within the peritoneal cavity. Given the potential for associated complications, we performed a cadaveric study to define the anatomic location of reservoirs placed in the high submuscular position via the inguinal canal. We secured 10 fresh male cadavers (prior to the embalming process) without history of prior intra-abdominal surgery. Bilateral submuscular ectopic reservoir placement was performed using published techniques via the inguinal canal. After placement, an anatomic dissection was performed to identify the location within the abdominal wall layers. Cadaver specific data, surgical technique, and anatomic reservoir location were recorded.
