[Duplex ultrasonography and internal pudendal arteriogram in the diagnosis of trauma-associated arteriogenic erectile dysfunction (a report of 7 cases)].
OBJECTIVE
To make a comparative study of duplex ultrasonography (DU) and internal pudendal arteriogram (IPA) in the diagnosis of trauma-associated arteriogenic erectile dysfunction (ED).


METHODS
Seven patients suffering from arteriogenic erectile dysfunction caused by pelvic fracture trauma underwent comprehensive history inquiries and physical examinations by duplex ultrasonography and internal pudendal arteriogram, which ruled out neurogenic erectile dysfunction.


RESULTS
DU suggested penile artery blood flow injury, and IPA indicated artery injury in all the cases, including left internal pudendal artery injury, right or left common penile artery injury and bilateral common penile artery injury.


CONCLUSIONS
Trauma-associated arteriogenic erectile dysfunction may result from common penile artery injury and internal pudendal artery injury. DU is proved valuable for evaluating hemodynamic abnormalities of cavernous artery flow, and IPA useful in locating common penile artery and internal pudendal artery injury. DU can be used as the first line diagnostic means to define trauma-associated arteriogenic ED.
