慢性前列腺炎的血流动力学特征

目的探讨慢性前列腺炎的血流动力学特征、，方法应用经直肠彩色多普勒检查66例慢性前列腺炎患者及38例正常人的前列腺。结果慢性前列腺炎组的前列腺外腺动脉及内腺动脉的内径（D）、最大血流速度（Vmax）、阻力指数（RI）均较正常组增大（P〈0．01），两组的外、内腺动脉最大血流速度比值（Vmax外彬Vmax内腺）和阻力指数比值（R1外彬R1内腺）无显著差异（P〉0．05）。Ⅲa型组的前列腺外、内腺动脉的各项参数与Ⅲb型组无显著差异（P〉0、05）。结论慢性前列腺炎患者的前列腺外、内腺血液供应增多，血流阻力增大，外腺血液供应较内腺丰富。Ⅲa型慢性前列腺炎及Ⅲb型慢性前列腺炎在血流动力学上无差异。

The hemodynamics characteristics of prostate in Chronic Prostatitis

Objective To study the hemodynamics characteristics of prostate in chronic prostatitis and evaluate the value of transrectal color doppler ultrasound in diagnosis.Methods 66 chronic prostatitis patients and 38 normal controls were examined by transrectal color doppler ultrasound.Results The arterial diameter(D),the maximum velocity(Vmax),resistance index(RI) of the outerland artery and the inner artery in chronic prostatitis were increased compared to controls(P<0.01).There was no significant difference in the ratio of the maximum velocity(outerland artery versus the inner artery)and the ratio of resistance index(outerland artery versus the inner artery) between chronic prostatitis and controls(P>0.05).There was no significant difference in the parameters of the outerland artery or the inner artery between NIH category IIIa and category IIIb(P>0.05).Conclusions The outerland artery and the inner artery in chronic prostatitis patients were in a state of high flow volume and high resistance,especially the former.There was no significant difference in hemodynamics between NIH category IIIa and category IIIb.
