彩色多普勒超声在糖尿病肾病诊断中的价值

目的：探讨彩色多普勒超声在诊断糖尿病肾病中的应用价值。方法：应用彩色多普勒血流显像对40例糖尿病肾病患者及20例年龄匹配的正常人的肾段动脉、叶间动脉进行检查，并对其血流的收缩期最大血流速度、舒张期最低血流速度和阻力指数进行对比分析。结果：糖尿病肾病组肾段动脉、叶间动脉收缩期最大血流速度、舒张期最低血流速度均较健康对照组减低，阻力指数增高（P〈0．01），且随着糖尿病肾病病情的进展，肾段动脉及叶间动脉收缩期最大血流速度、舒张期末最低血流速度逐渐减慢，而阻力指数逐渐增高（P〈0，01）。结论：彩色多普勒超声检测糖尿病肾病肾血管血流参数的变化对早期诊断糖尿病肾病有一定价值。

The study of the value of color doppler flow images in the diagniosis of early diabetic nephropathy

Objective：To study the value of color doppler flow images in diagnosis of diabetic nephrpathy. Methods： Renal segmental artery and interlobal artery blood flow parameter was measured in all 40 patients who lind diabetic nephrpathy and 20 healthy persons by color doppler flow images, and compared their the peak-systolic, the end-diastolic velocity and the resistance index. Results： In group of patients who had diabetic neptupathy, the renal segmental artery, interlobal artery＇s the peak-systolic, and the end-diastolic velocity were lower than those in contrast group, while the resistance index was higher titan contrast group（all P 〈 0.01）. Following the progression of the diabetic nephrpathy, the renal segmental artery, interlobal artery＇s the peak-systolic, and the end-diastolic velocity became lower, and the resistance index became higher（ P 〈 0.01 ）. Conclusion： The renal blood flow parameter from color doppler has a certain reference value in predicting renal lesions of diabetic nephrpathy.
