Three hundred and twenty patients with erec tile failure were included i11 our study (cases with psychological, neurological and hormonal factors were excluded). 246 patients
-6.8%) with suspected vasculogenic impotence underwent color Doppler ultrasonography testing for the cavernosal arteries after tmracavernous injection of 30 mg papaverine
HCI. The maximum mean peak systolic velocity of the cavernosal arteries, the end diastolic velocity and resistance index were determined. It was found that 9 patients (3.66%)
had normal findings, 22 (8.94%) had pure aterial insufficiency, 143 (58.13%) had pure venous leakage while 72 (29.27%) had combined arterial and venous dysfunction. Also,
we found that diabetes mellitus could be considered as a risk factor in arterlogenic group (18.18%),
( 34.72%) venogenic group (29.36%) and combined arterial and venous group
aminationIt appears that venous leak could be suspected from the results of Doppler
examination. Patients with pure venous leakage underwent Dynamic cavemosography for the confirmation of the diagnosis and detection of the side and severity of venous leakage. fl was found that unilateral leak was detected in 59 patients (41.25%) and bilateral leakage 84 (58. 75%). According to the maintenance [low, the severity of leakage was detected. I 0 cases
6.99%) had mild leak, 22 cases (15.31%) had moderate leak, while 111 cases (77. 70%) had severe leak
