彩色多普勒超声在高血压合并糖尿病肾损害的应用价值

Value of color Doppler ultrasound in the evaluation of renal damage in patients with hypertension complicated with diabetes

目的:探讨彩色多普勒超声在高血压合并糖尿病肾损害的应用价值。方法:64例高血压合并糖尿病患者根据尿微量蛋白水平分为A,B两组,A组(34例)为尿微量蛋白增高组,B组(30例)为尿微量蛋白正常组,另40例健康体检者为对照组C组,三组均行彩色多普勒超声检查,比较三组肾皮质及肾段动脉、叶间动脉收缩期峰值流速(Vmax)、舒张末期流速(Vmin)和阻力指数(RI)。结果:A组肾皮质厚度明显大于B组及C组(P均<0.01),但B组与C组比较无显著差异(P>0.05);A组肾动脉RI明显高于B组及C组(P<0.01);B组RI明显高于C组(P<0.01)。结论:彩色多普勒超声对肾脏及其血流的检测,可用于判断预测高血压合并糖尿病患者早期肾损害。

Objective. To explore the diagnostic value of color Doppler ultrasound in the evaluation of renal damage in patients with hypertension complicated with diabetes. Methods. A total of 64 patients with hypertension and diabetes were divided into group A and group B according to urine microalbumin level, which was increased in 34 patients in group A and was in normal rang in 30 cases of group B. Besides, 40 healthy volunteers were also enrolled as group C. All three groups underwent color Doppler ultrasound examination for comparison of interlobar artery peak systolic velocity （Vmax）, end diastolic velocity （Vmin） and resistance index （RI） of renal cortex and renal segmental arteries. Results：Renal corti- cal of group A was significant thicker than that of group B and group C （P^0.01）, but no significant difference was found between group B and group C （P〉0.05）. Renal artery RI of group A was significant higher than that of group B and C （P〈0.01） ; renal artery RI of group B was significant higher than that of group C （P〈0.01）. Conclusions： Color Doppler ultrasound detection of kidney and its blood flow can used for evaluation and prediction of renal damage in patients with hypertension complicated with diabetes.
