Results Of the 29 patients, 1 was psychological, 28 were physical, 7 vascular , and 15 neurological. Rigiscan and Duplex ultrasound revealed the cause of erectile failure as neurogenic in 15. Twenty three cases were effective by the therapy.The injection with vasoactive agents(prostagland in E 1) was successful in 15, Viagra in 2, Befar in 5, and revascularization of epigastric artery dorsal artery anastomosis in 1. Conclusion Disruption of the cavernous nerves lateral to the prostatomembranous urethra is the most likely cause of ED in this injury.
