[摘要] 目的 探讨彩色多普勒超声用于早期糖尿病肾病(Diabetic nephropathy，DN)诊断的临床应用价值。方法 选择该院2015年2月—2016年10月收治的DN患者80例为观察组，选择同期健康体检人员80名为对照组，采用彩色多普勒超声检查，比较两组患者肾脏长径、前后径、左右径、体积，肾脏血流EDV、PSV、Vm、PI、RI。肾脏实质分级与血流分级情况。结果 观察组患者肾脏大小与体积显著大于对照组(P<0.05)；两组患者肾脏实质、血流各级别比较差异有统计学意义(P<0.05)；观察组患者的EDV、PSV、Vm显著低于对照组，PI、RI显著高于对照组(P<0.05)。结论 彩色多普勒超声检查可以早期诊断DN，可根据肾脏体积大小，肾脏血流灌注、血流参数等情况判断患者疾病情况。
