彩超在男性阴茎勃起功能障碍中的应用

摘要

目的：探讨彩超在男性阴茎勃起功能障碍（ED）临床治疗中的作用，以期提高治疗水平。方法：随机选取2010年4月至2013年4月309例ED患者为研究对象，分成两组，均予以彩超检查；观察组予以他达拉非10mg口服，对照组服用安慰剂，观察用药前后在阴茎深动脉收缩期峰值流速（PSV）、舒张期末期最小流速（EDV）、阻力指数（RI）和直径（D）的变化情况和阴茎深动脉D增大率变化情况。结果：在ED构成比率上两者比较无明显差异性（P＞0.05），而从组间PSV情况看，动脉性ED组最小、复合性ED其次，静脉性ED组再次，非血管性ED组最大；从EDV情况看，静脉性ED组和复合性ED组明显高于其他两组（P＜0.05）；从RI情况看，非血管性 ED 组明显高于其他3者（P＜0.05），组间比较有明显差异性（P＜0.05）。结论：彩超能为临床上ED的诊断提供良好客观依据。%Objectives:To investigate the clinical effect of color doppler ultrasound (CDU)in male erectile dysfunction (ED)in order to improve the level of clinical treatment.Methods:309 ED patients in our hospital from A-pril 2010 to April 2013 were randomly selected and divided into two groups to receive CDU examination.Observation group took 10mg oral tadalafil,while control group took placebo.Deep penile artery peak systolic velocity (PSV),end-diastolic flow velocity of the smallest (EDV),resistance index (RI)and diameter (D)changes and penile deep arteries D increase rate were observed before and after treatment.Results:The ED component ration of the two groups was of no significant difference (P>0.05);while from the perspective of interblock PSV,the arterial ED was lowest,followed by compound ED,intravenous ED and non-vascular ED;in terms of EDV situation,venous and compound ED were signifi-cantly higher than the other two groups (P<0.05);as for RI situation,non-vascular ED was significantly higher than the other three groups (P<0.05),with significant differences between groups (P<0.05).Conclusions:CDU can pro-vide a good objective basis for clinical diagnosis of ED.
