The inflatable penile prosthesis (IPP) is a three-piece device indicated to treat erectile dysfunction. Although it is considered a safe procedure, it can result in complications, such as reservoir herniation. Literature is scarce regarding reservoir incarcerated herniation as a complication of IPP and its management. Surgery is required to reduce symptomatic hernias and properly secure the reservoir to avoid recurrence. An untreated incarcerated hernia may lead to strangulation and necrosis of abdominal organs, as well as implant malfunction. We present a rare case of a left-sided incarcerated inguinal hernia containing fat and a penile reservoir of a previous penile prosthesis implant in a 79-year-old man, as well as the technique used to correct it.
