Risk factors of erectile dysfunction and penile vascular changes after surgical repair of penile fracture.

This study was conducted to determine the preoperative and intraoperative risk factors of ED and the underlying penile vascular abnormalities among patients with penile fracture treated surgically. In all, 180 patients with penile fracture were treated surgically and followed up in one center. None of our patients had ED before the penile trauma and only two of them had risk factors for systemic vascular diseases, such as diabetes mellitus (one patient) and hypertension (one patient). After a mean follow-up of 106 months, 11 patients (6.6%) developed ED, 7 had mild ED and 4 had moderate ED. The main risk factors for subsequent ED were aging, >50 years, and bilateral corporal involvement. Among the 11 patients with ED, color Doppler ultrasonography (CDU) showed normal Doppler indices in 4 (36.4%), veno-occlusive dysfunction in 4 (36.4%) and arterial insufficiency in the remaining 3 (27.2%) patients. CDU assessments from the injured and intact sides were comparable. ED of either a psychological or vascular origin can be encountered as a long-term sequel of surgical treatment of penile fracture. Aging, >50 years, at presentation and bilateral corporal involvement is the main risk factors for subsequent development of ED.
