[Duplex scanner in the diagnosis of vasculogenic impotence].

This paper is reporting the experience of the Authors in the use of Duplex-scanner and eco-color-doppler in the diagnosis of the erectile dysfunctions and particularly in the importance of vascular (arterious and venous) origin. For this purpose, we selected a sample constituted of 41 patients: 22 with psychogenic, 8 with arterial, 5 with venous impotence, 5 patients with Peyronie's disease and 1 patient with posttraumatic arterio-venous fistula. The Authors, while underlining the remarkable accuracy and diagnostic reliability of eco-doppler, emphasize the indication of the method up to consider it "investigation of prime choice", not only in the patients with the dysfunction of vis erigendi but, in the cases in which a morphological evaluation, besides hemodynamical one, become necessary.
