彩色多普勒超声在诊断血管性勃起功能障碍的应用方法及价值探讨

目的：探讨彩色多普勒超声检查对血管性勃起功能障碍（ED）诊断及分型的方法及价值。方法：应用彩色多普勒超声结合阴茎海绵体血管活性药物注射和刺激结合实验（CIS）测定259例ED患者诱导前后阴茎大小、阴茎海绵体动脉及阴茎背深静脉血流动力学变化。结果：259例患者中非血管性ED 35例（13.5%），动脉性ED 58例（22.4%），静脉性ED 47例（18.2%），混合性ED 119例（46%）。勃起后非血管组的PSV、EDV及RI均高于动脉性、静脉性、混合性ED组（P＜0.05）。静脉组阴茎背深静脉速度高于非血管组、动脉组，有显著差异（P＜0.05）。结论：彩色多普勒超声是诊断血管性ED的有效方法。

Application and value of color Doppler uitrasonograghy in the diagnosis of vasculogenic erectile dysfunction

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.
