title: [A comparison of color duplex sonography with selective penile DSA in assessing erectile dysfunction].
abstract: 42 patients with suspected vasculogenic impotence were examined via colour duplex sonography. Penile vascular anatomy was mapped and peak velocity was determined in both cavernous arteries before and after intracorporeal injection of 15 mg papaverine and 0.5 mg regitine. In all patients the results could be compared with selective penile pharmacoangiography as the gold standard. In 34/42 patients colour Duplex sonography and angiography led to an identical evaluation of penile blood supply. 4 patients were classified false-negative and 4 patients false-positive. Sensitivity and specificity were calculated for each side separately. Sensitivity was 82.4% for left side angiogram and 83.3% for right side angiogram. Specificity was 88% for left side angiogram and 87.5% for right side angiogram. Peak flow velocity was significantly diminished in pathological angiograms.
