Modified Abdominal Wall Reservoir Placement during Penile Prosthesis Implantation in Chinese Patients with Traumatic Pelvic Erectile Dysfunction

Background: The placement of reservoir during penile prosthesis implantation (PPI) surgery is a challenge for those patients with traumatic pelvic erectile dysfunction. Objective: This study aims to investigate a modified abdominal wall reservoir placement during PPI in Chinese patients with traumatic pelvic erectile dysfunction. Methods: We conducted a retrospective review of PPI procedures performed between January 2015 and June 2023, with a specific focus on cases where the reservoirs were positioned posteriorly to the musculature of either the left or right abdominal wall. A total of 27 patients, with a mean age of 32years ( interquartile range, IQR: 24-50), and the mean duration after pelvic fracture to PPI was 84 months (IQR: 18-168),were included in this study. Fracture patterns were categorized as lateral compression (LC) (44.4%), anteroposterior compression (APC) (30%), and vertical shear (VS) (25.6%), and 70% of the patients experienced urogenital injuries Results: Following the surgery, the mean IIEF-5 scores of these patients improved significantly, rising from 5.72±0.13 to 22.15±1.26. All dimensions of the SF-36 quality of life scale demonstrated substantial improvement except for vitality. Overall satisfaction rates for both patients and their partners after PPI surgery were 91.0% and 87.5%, respectively. Notably, only two patients (7.41%) experienced postoperative pain or foreign body sensation, which resolved during follow-up. 1 prothesis was removed due to infection (3.70%), 2 prothesis was revised due to pump malfunction (7.41%). Conclusion: The placement of an abdominal wall reservoir is a straightforward and safe surgical technique that can be recommended for men with traumatic pelvic erectile dysfunction undergoing PPI surgery.
