摘要
目的探讨彩色多普勒超声对诊断早期糖尿病肾病的临床价值。方法以24小时微量尿蛋白排泄率(UAER)作为糖尿病肾病的诊断指标,将60例糖尿病患者,分为三组,20例正常人为对照组,以彩色多普勒超声分别检测肾体积及肾各级动脉的血流参数进行统计学分析。结果随着肾功能损害加重,肾动脉的收缩期峰值流速、舒张末血流速度下降,血流阻力指数(RI)增高,以RI增高与肾功能损害程度相关最密切。大量蛋白尿组体积缩小,与各组差异非常显著,余各组间无显著差异。结论彩色多普勒超声测定肾动脉血流参数,能反映糖尿病肾病肾损害程度,可作为早期糖尿病肾病诊断的参考指标。
Objective To evaluate the value of color Doppler ultrasound in the diagnosis of early diabetic nephropathy. Methods Sixty patients with diabetes mellitus classified into three groups according to urinary albumin excretion rate（UAER） and compared with twenty cases of normal persons, renal size and blood flow parameters of renal arteries were measured and analyzed by color Doppler ultrasound, Results Following the process of renal dysfunction, the peak-systolic velocity （PSV） and the end-diastolic velocity （EDV） of renal arterial flow decreased, the resistance index （RI）increased, RI correlated well with the renal dysfunction of diabetic mellitus. The renal volume in UAER〉 300mg group reduced and had significant difference with other groups （P〈0.001）. There was no significant difference between other groups, （ P〉0.05）. Conclusion Color Doppler ultrasound may evaluate renal dysfunction of diabetic mellitus by measuring renal flow parameters and may be an index to diagnose diabetic nephropathy early.
