نبذة مختصرة : Purpose: To describe a case of safe placement of an inflatable penile prosthesis reservoir for postoperative erectile dysfunction (ED) with a history of radical cystoprostatectomy with an orthotopic Studer neobladder. Materials and Methods: A 55-year-old bladder cancer patient, who underwent radical cystoprostatectomy with orthotopic Studer neobladder 2 years prior, suffered from postoperative ED. A 3-piece inflatable penile prosthesis was implanted via a penoscrotal incision. The alternative reservoir placement began with a longitudinal 4-cm incision, which was 2 finger-breaths to the left and lateral to the umbilicus. Thereafter, the anterior and posterior rectus sheaths were dissected and incised. Then, the transversalis fascia entering into the preperitoneal space was incised, followed by circumferential sweeping using the forefinger, and, finally, placement of a 100 mL ‘flat’ reservoir. The reservoir was filled with 65 mL saline and then evaluated for back pressure. The reservoir tubing exited through the defect of the rectus sheaths and tunneled through the abdominal fat into the penoscrotal wound. Results: Total operative time was 105 minutes, and the estimated blood loss was minimal. The patient was discharged at postoperative day 1 and experienced no perioperative complications. At the 6-month follow-up, there was no abdominal bulging from the preperitoneal reservoir, and the reservoir was not palpable. Conclusions: The preperitoneal placement of the flat reservoir at the level of the umbilicus is a safe and acceptable surgical technique for postoperative ED after radical cystoprostatectomy with orthotopic neobladder.
