Abstract
This study aims to investigate a modified abdominal wall reservoir placement during penile prosthesis implantation (PPI) in Chinese patients with traumatic pelvic erectile dysfunction. A total of 27 patients, with a mean age of 32years (IQR: 24-50), and the mean duration 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. All patients were provided with a follow-up questionnaire consisting of four portions: IIEF-5, SF-36 scores , Bhojwani’s sexual satisfaction score and complications. Following the surgery, the mean IIEF-5 scores improved significantly, rising from 5.72±0.13 to 22.15±1.26. The SF-36 quality of life scale demonstrated substantial improvement except for vitality. Overall satisfaction rates for patients and their partners 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%). Modified abdominal wall musculature placement will be suited to those patients with altered pelvic anatomy as a result of trauma and prior surgery.
