Abstract：Objective: To analyze the effect of color Doppler ultrasonograghy to the diagnosis and stage of vasculogenic erectile dysfunction(ED). Methods: The hemodynamic changes of the cavernous artery and the deep dorsal vein, before and after having injected vasoactive agents into the cavernous body in 259 patients using color Doppler ultrasonograghy were observed. Results: There were 35 cases(13.5%) with non-vasculogenic ED, 58 cases(22.4%) with arteriogenic ED, 47 cases(18.2%) with venogenic ED, 119 cases(46%) with mixed vascular ED. When penis was erected, PSV(peak systolic velocity), EDV（end-diastolic velocity）and RI(resistance index) in the group of non-vasculogenic ED was obviously higher than those in the groups of arteriogenic ED, venogenic ED and mixed vascular ED(P＜0.05). Deep dorsal vein velocity in the group of venogenic ED was obviously higher than those in the groups of non-vasculogenic ED and arteriogenic ED(P＜0.05). Conclusion: The result of color Doppler ultrasonograghy examination effectively helps the diagnosis and stage of vasculogenic ED.
