The authors report their experience with color-Doppler US in the study of 54 male patients with sexual impotence. The examination includes two distinct phases; in between, the erection-inducing drugs is injected directly in the cavernous bodies. During the basal phase, B-mode information relative to both morphology and structure of cavernous bodies is collected. After injecting the drug, systolic and end-diastolic velocities are evaluated as flowmetric indices, together with the resistive index; these variables are derived from cavernous arteries, at scheduled time--i.e., 5, 10 and 20 minutes after the injection. Moreover, the examined patients were divided into 4 groups according to their clinical response to the pharmacologic test. Color-Doppler US proved to be quite sensitive in the identification of the patients with a vascular alteration, both venous and arterial, underlying their erectile dysfunction; as a matter of fact, venous flights are easily depicted with the use of colors. The authors believe that color-Doppler could eventually become a major exam in the diagnosis of sexually impotent patients, thus allowing the marked reduction of such invasive diagnostic techniques as selective angiography of internal pudendum arteries and dynamic cavernosography, which are poorly tolerated by the patients.
