摘　　要：目的探讨多普勒超声肾脏血流阻力指数对肾积水肾功能可复性评估的临床应用价值。方法采用多普勒超声检测53例梗阻性肾积水患者的动脉血流参数[收缩期最大峰值流速(PSV)、舒张期最低流速(EDV)、阻力指数(RI)],并进行术前、术后3、6个月的随访观察,同时与静脉尿路造影(IVU)和肾图对比。结果中度、重度肾积水组PSV、EDV、RI与正常对照组比较,均有显著性差异(P均<0.01),轻度肾积水组EDV与正常对照组比较,有显著性差异(P<0.01),轻度、中度、重度肾积水组术后3、6个月RI分别与术前比较,均有显著性差异(P均<0.01)。结论肾动脉阻力指数对肾积水肾功能的可复性评估提供了一种简便有效的方法。Objective to investigate the meaning of re：5istive index in evaluating value reversible changes of fenal function. Methods The resistive index （RI） in fifty-three cases of hydronephrot- ic kidney were observed and compared before and after operation （3 months and 6 months）. All patients were examined for intravenous urography and nephrogram. Results PSV,EDV,RI value in moderate and severe hydronephrosis versus control group were statistically significant. （P〈 0.01） EDV value in mild hydronephrosis versus control group was statistically significant. （P〈 0.01） In mild, moderate and severe hydronephrosis, RI value was statistically significant before versus after operation （3 months and 6 months）. （P〈0.01）. Conclusion RI offers a simple ,effective and reliable method for diagnosis and reversible changes of renal function.
