彩色多普勒超声对肝硬化的肾血流动力学改变的研究

目的 评价彩色多普勒超声对肝硬化的肾血流动力学变化的研究价值.方法 应用彩色多普勒技术检测13例肝硬化腹水组、13例肝硬化无腹水组和24例正常对照组的肾血流动力学,并互相进行对照.结果 肝硬化腹水组的阻力指数（RI）、肾血流量（Q）与肝硬化无腹水组、正常对照组比较,具有显著性的差异（P＜0.01）;肝硬化无腹水组的阻力指数、肾血流量与正常组比较,无显著性差异（P＞0.05）.结论 彩色多普勒超声能无创的监测肝硬化对肾血流的影响,对病情的监测、HRS的预测提供重要的价值.

Color Doppler Sonographic Study on Renal Hemodynamics in Hepatic Cirrhosis

Objective To evaluate the value of color Doppler in detecting the renal hemodynamic changes in hepatic cirrhosis.Methods Renal arterial hemodynamics were studied in 13 nonascitic and 13 ascitic patients with normal kidney function and compared with 24 healthy controls.Results The resistive index and renal blood volume were significant difference in cirrhosis with ascites than in cirrhosis without ascites and healthy controls (P<0.01).However,the resistive index and renal blood volume in cirrhosis without ascites had no significant difference with those in healthy controls(P>0.05).Conclusions Color Doppler ultrasonography can noninvasively identify the development of renal hemodynamics in cirrhotic patients,and monitor the progress of the disease and to predict hepatorenal syndrome.
