title: Penile blunt trauma induced veno-occlusive erectile dysfunction.
abstract: Blunt trauma to the pelvic or perineal region of the corpora cavernosa is a risk factor for the subsequent development of persistent erectile dysfunction. The hemodynamic investigation of the integrity of the veno-occlusive mechanism has been rare in cases of traumatic impotence. We present two young men with erectile dysfunction following blunt penile or perineal trauma. Combined intracavernous injection and stimulation test, color duplex ultrasonography, and pharmacologic cavernosometry and cavernosography revealed normal arterial velocity and pulsation without cavernosal arterial fistula, but severe venous occlusion and site-specific abnormal veins were noted in both patients. They received penile vein ligation procedure and resulted in near-completely normal erectile function after a four-year followup. Penile venous ligation, especially on the site-specific veins, is still the choice of treatment for the trauma-induced penile veno-occlusive erectile dysfunction, and the result is satisfactory.
