三维能量多普勒及彩色多普勒超声评估慢性肾脏病肾损害的价值

Value of three-dimensional power Doppler and color Doppler ultrasound for assessment of renal damage caused by chronic kidney disease

目的探讨三维能量多普勒(3D-CPA)超声参数血管指数(VI)及肾叶间动脉阻力指数(RI)评估慢性肾脏病(CKD)肾损害的价值。方法选择50例慢性肾脏病患者进行3D-CPA及彩色多普勒检查,计算血管指数(VI)及阻力指数(RI),与正常对照组30例比较。结果不同分期的慢性肾脏病有不同的VI及RI值。VI与CKD分期呈正相关,RI与CKD分期呈负相关。结论 VI和RI均能无创的反映CKD的血流变化,为疾病的诊断、治疗、监测提供依据。

Objective To investigate value of the three-dimensional power Doppler （3D-CPA） ultrasound parameters of vascular index （VI） and renal interlobar artery resistance index （RI） for the assessment of renal damage caused by chronic kidney disease （CKD）. Methods Fifty patients with chronic kidney disease were given 3D-CPA and color Doppler examina- tion, VI and RI were calculated and compared with 30 normal peoples. Results The different stages of chronic kidney dis- ease had different VI and RI values. There was a positive correlation between VI and CKD stage, while there was negative correlation between RI and CKD stage. Conclusion VI and RI can noninvasively reflect blood flow changes of CKD patients, provide the basis for disease diagnosis, treatment and monitoring.
