[The value of dynamic color duplex scanning in the diagnosis of vascular erectile dysfunction].
OBJECTIVE
To evaluate deep penile arterial flow after an intracavernosal injection with prostaglandin E1 in patients with erectile dysfunction (ED).


METHODS
527 patients with ED were evaluated using Color Doppler Ultrasonography. Diagnostic tests were undertaken after an intracavernosal injection with 20 microg prostaglandin El. The peak systolic velocity (PSV), end diastolic velocity (EDV) and resistive index (RI) were analysed.


RESULTS
There were 112 patients (26.99%) with nonvasculogenic ED, 207 patients (49.88%) with arteriogenic ED, 144 patients (34.70%)with venogenic ED, 64 patients (15.42%)with mixed ED.


CONCLUSIONS
The Color Doppler Ultrasonography technique allows accurate location and evaluation of deep penile arteries. Vascular pathology may be differentiated after an intracavernosal injection with a vasomotor agent. Recognising the pathological pattern assists in choosing the best method of treatment.
