COMPARISON OF COLOR-CODED DUPLEX SONOGRAPHY AND SELECTIVE PENILE PHARMACOANGIOGRAPHY FOR THE EVALUATION OF ARTERIOGENIC IMPOTENCE

42 patients with suspected vasculogenic impotence were examined via co lour Duplex sonography. Penile vascular anatomy was mapped and peak ve locity was determined in both cavernosal arteries before and after int racorporeal injection of 15 mg papaverine and 0,5 mg regitine. In all patients the results could be compared with selective penile pharmacoa ngiography as the gold standard. In 34/42 patients colour Duplex sonog raphy and angiography led to an identical evaluation of penile blood s upply. 4 patients were classified false-negative and 4 patients false- positive. Sensitivity and specificity were calculated for each side se parately. Sensitivity was 82.4 % for left side angiogram and 83.3 % fo r right side angiogram. Specificity was 88 % for left side angiogram a nd 87.5 % for right side angiogram. Peak flow velocity was significant ly diminished in pathological angiograms.
