目的：利用彩色多普勒能量显像技术(CDE)探讨不同程度肾积水患者肾脏的血流灌注及其临床意义。方法：应用二维超声和CDE技术对155例162只积水肾和45例对照组90只正常肾进行了检测，对比分析不同程度肾积水的肾脏体积、肾皮质厚径、主肾动脉血流动力学变化及CDE灌注情况。结果：轻度肾积水时肾体积无增大，皮质厚度正常，CDE显示肾内血流丰富，主肾动脉血流参数与正常人无差异(P>005)。中度肾积水时肾体积略增大，皮质减薄，与正常人有差异(P<005)，CDE显示肾内血流仍丰富，主肾动脉血流参数与正常人无差异(P>005)。重度肾积水时，肾体积增大，皮质变薄，CDE显示肾内血流有减少，主肾动脉血流速在收缩期无变化，舒张期减低，阻力指数增高，与对照组差异显著(P<0001)。极重度肾积水时，肾体积明显增大，皮质菲薄，CDE显示肾内血流进一步减少，主肾动脉血流速在收缩期、舒张期均降低，阻力指数增高，与对照组差异显著(P<0001)。结论：肾积水的肾脏CDE表现，反映了肾脏的血流灌注情况，对肾积水的程度、诊断、治疗监测和评估预后都有重要的意义。

Objective:To study the renal blood flow perfusion and itsclinical significance in hydronephrosis by Color Doppler Energy(CDE).Methods:155 cases(162 kidneys) of hydronephrosis and 45 healthy persons as control group were examined by ultrasonography and CDE.The renal volume,renal cortex thickness,main renal artery blood flow perfusion and hemodynamic in different degree of hydronephrosis were analyzed and compared with control group.Results:In group of mild hydronephrosis,the renal volume,cortex thickness,renal blood flow perfusion and distribution main renal artery flow parameter had no difference compared with control group (P>005).In group of moderate hydronephrosis,the renal volume increased,the cortex became thin significantly(P<005),but the renal blood perfusion and parameters had no differences compared with control group(P>005).In groups of severe and very severe hydronephrosis,the renal volume increased more,the cortex became thinner,the renal blood perfusion decreased and the RI (resistance index)increased very significantly (P<0001).Conclusion:CDE can show the renal blood perfusion and is useful in diagnosing,monitoring treatment and estimating prognosis of hydronephrosis.
