摘　　要：目的探索阴茎疲软状态下海绵体动脉收缩期最大流速(peak systolic velocity,PSV)对动脉性ED的预测作用及具体预测值。方法随机入组男科门诊ED患者337名,并对比疲软和勃起状态下的PSV。结果入组患者中,有68名患者确诊为动脉性ED。该部分患者阴茎疲软状态下海绵体动脉PSV与勃起状态下PSV显著相关(P<0.01),接受者操作特性曲线(receiver operating characteristic curve,ROC曲线)分析显示,当疲软状态下PSV小于15cm/s时,预测勃起状态下PSV小于30cm/s的准确率为82%。通过对患者焦虑自评量表(self-rating anxiety scale,SAS)的得分评估还发现,焦虑情绪会对勃起状态下PSV检测结果产生影响(P<0.05),但不会对疲软状态下的PSV检测结果产生影响。结论初步结论显示,阴茎疲软状态下海绵体动脉PSV对勃起状态下的PSV具有一定的预测意义,准确率可达82%。Objectives To investigate the predictive value of peak systolic velocity （PSV） measured in the flaccid state for arteriogenic ED. Methods 337 ED out-patient patients were randomly recruited in the study. The PSVs of flaccid state and full erection state were measured and comparatively analyzed. Results In all enrolled patients, 68 were diagnosed as arteriogenic ED. In these 68 arteriogenic ED patients, a significant correlation in PSVs was ob- served between flaccid state and full erection state （P〈0.01）. The receiver operating characteristic curve （ROC curve） also showed that the PSV of full erection state less than 30cm/s could be predicted, with an accuracy of 82% under PSV of flaccid state less than 15cm/s,. Based on results of self-rating anxiety scale （SAS）, the PSV of full erection state, but no the PSV of flaccid state, was found to be affected by the anxiety emotion （P〈0.05）. Conclusion The primary results showed that the PSV of full erection state, with an accuracy of over 80% could be predicted by the PSV of flaccid state.
