摘　　要：目的 探讨肾积水中肾皮质内小叶间动脉血流变化及临床意义。方法 测量60例肾积水患者肾皮质内小叶间动脉收缩期末、舒张期末血流速度及阻力指数(RI),并与100例正常肾脏皮质内小叶间动脉血流对比分析。结果 轻度肾积水患者皮质内小叶间动脉收缩期末血流速度与正常对照组无明显差异(P>0.05),RI升高(P<0.01),重度肾积水患者皮质厚度变薄、皮质内小叶间动脉收缩期末、舒张期末血流速度均减慢,RI升高(P<0.01)。结论 肾皮质内动脉血流变化的多普勒表现在肾积水诊疗中具有重要意义。Objective To study the changes and clinical significance of cortex interlobukr arterial blood flow in hydronephrosis.Methods The end-systolic,end-diastolic velocity and resistance index(RI) in 60 cases of hydronephrosis and 100 normal subjects were measured and analysed. Results There were not significant difference between patients with mild hydronephrosis and normal controls in end-systolic velocity ( P>0.05),but RI increased in the patients ( P < 0.01). The end-systolic and end-diastolic velocity in patients with severe hydronephrosis decreased, but the RI increased ( P < 0.01). Conclusion Ultrasonic manifestation of the cortex interlobular arterial blood flow changes is of significance for the diagnosis and treatment of hydronephrosis.
