粥样硬化性肾动脉狭窄与慢性肾衰竭的关系

The relationship between atherosclerotic renal artery stenosis and chronic renal failure

目的通过对237例慢性肾衰竭患者的资料进行分析,了解粥样硬化性肾动脉狭窄为主要病因所占的比例,总结粥样硬化性肾动脉狭窄的临床表现及诊断方法。方法对237例慢性肾衰竭患者进行肾功能检测及彩色多普勒、CT、磁共振血管造影(MRA)和选择性血管造影等检查。结果237例慢性肾衰竭患者中有42例(17.72%)为单独或合并其他疾病的粥样硬化性肾动脉狭窄,彩色多普勒诊断正确率为95.8%。结论粥样硬化性肾动脉狭窄是慢性肾衰竭的一个重要病因,彩色多普勒对筛选粥样硬化性肾动脉狭窄有意义。

Objective To study the ratio of the chronic renal failure, which caused by atherosclerotic renal artery stenosis, understand the clinical findings and the way of diagnosis. Methods The examination of renal function, Color Doppler, CT, MRA and conventional renal angiography had performed in 237 cases with chronic renal failure. The data were statistically analyzed. Results 42 of 237 （ 17.72% ） cases with chronic renal failure were complicated with atherosclerotic renal artery stenosis ,the accuracy of diagnosis of Doppler was 95.8%. Conclusion Atherosclerotic renal artery stenosis is one of the important reasons for chronic renal failure, and Doppler plays an important role in the diagnosis of atherosclerotic renal artery stenosis.
