阴茎动脉Doppler超声分析

Analysis of Doppler Ultrasonography in Penile Artery

目的研究健康成年男性阴茎背动脉(DA)、海绵体动脉(CA)PI、RI及S/D的正常值。方法将257名健康成年男性按年龄分为5组,分别为<30岁组65名,30～39岁组83名,40～49岁组61名,50～59岁组38名,60岁以上组10名。用Logidop!2型数字式Doppler超声血流仪检查双侧阴茎背动脉、双侧海绵体动脉PI、RI及S/D值。结果阴茎疲软状态下,阴茎背动脉、海绵体动脉PI、RI和S/D值个体左右比较无差异,各年龄组也无差异。建议正常参考值分别为:(1)LDA:PI1.43～3.43,RI0.72～0.92,S/D2.68～10.56。(2)RDA:PI1.47～3.47,RI0.73～0.93,S/D3.27～10.09。(3)LCA:PI1.49～3.21,RI0.74～0.90,S/D3.17～9.55。(4)RCA:PI1.93～3.27,RI0.72～0.90,S/D3.22～9.42。结论作为一种筛选手段,Doppler超声血流检测手段,有一定的应用价值。

Objective To study nomal valuels of PI, RI and S/D in healthy male penile dorsum artery （DA） and cavernosal artery （CA）. Methods 257 healthy mature men were divided into 5 groups by age. Group 1： 〈30, n=65; Group 2： 30-39, n=83; Group 3： 40-49, n=61; Group 4： 50-59, n=38; Group 5： ≥ 60, n=10. Hibateral PI, RI and S/D values of penile dorsum artery and cavernosal artery were examined by Logidop（r）2 Type Digital Doppler Uhrasonography. Results There were no significant difference for PI, RI and S/D of penile dorsum artery and cavernosal artery not only in personal left and right artery but also in different age groups. Normal values advised： ①LDA：PI 1.43-3.43, RI 0.72-0.92, S/D 2.68-10.56. ②RDA PI 1.47-3.47, RI 0.73-0.93, S/D 3.27-10.09. ③LCA：PI 1.49-3.21, RI 0.74-0.90, S/D 3.17-9.55. ④RCA：PI 1.93-3.27, RI 0.72-0.90, S/D 3.22-9.42. Conclusion Doppler uhrasonography is a favorable method in filtering penile arterial function.
