[Selective arteriography of the internal pudendal artery in posttraumatic erectile dysfunction]

102 patients with erectile dysfunction were evaluated by a multidisciplinary approach including measurement of the bulbocavernous reflex (BCR)-latency, cystometry, dynamic cavernosography and bilateral selective arteriography of the pudendal arteries. Seven patients had a posttraumatic source of their erectile failure. Three patients showed a mixed neurogenic-arteriogenic aetiology of erectile dysfunction, two patients had evidence of isolated arterial damage, one patient had a venous and one an isolated neurogenic cause of erectile dysfunction. The passage of pudendal-penile vessels and nerves through the urogenital diaphragm is the most vulnerable portion of its way through the pelvis. Ruptures of the prostatomembranous urethra are frequently accompanied by injury to the pudendal-penile vessels and nerves, thus causing erectile dysfunction.
