目的：探讨多普勒超声测量正常儿童肾动脉血流参数的临床价值，为临床儿童肾脏疾病诊治提供参考。方法选取300名体检正常的健康儿童，采用彩色多普勒超声测量主肾动脉（MRA）、段动脉（SA）和叶间动脉（ILA）的频谱，计算舒张末期峰值（Vd）、收缩期血流峰值流速（Vs）、平均血流速度（Vm）、收缩期血流峰值流速与舒张末期血流峰值流速比值（S/D）、阻力指数（RI）、搏动指数（PI）、收缩期血流加速时间（AT）等。结果正常儿童肾动脉血流参数与体表面积（BSA）之间具有良好相关性，Vd、Vs、Vm与 BSA间呈正相关（均 P ＜0．05），S/D、RI、PI与BSA间呈负相关（均P ＜0．05）；不同肾动脉分级血流参数中Vd、Vs、Vm、S/D、RI、PI比较差异具有统计学意义（ P ＜0．05），MRA、SA、ILA呈现依次递减趋势，AT比较差异无统计学意义（ P ＞0．05）。结论多普勒超声测量正常儿童肾动脉血流参数结果与儿童BSA之间具有良好相关性，可为临床儿童肾脏疾病诊治提供参考。

Objective To explore the Doppler ultrasound measurement of the clinical value of renal artery blood flow parameters of normal chil-dren in order to provide reference data for clinical diagnosis and treatment of kidney disease in children .Methods Three hundred healthy children under-going physical examinations were selected and the main renal artery(MRA),segmental artery (SA),and leaf between artery (ILA) spectrum were meas-ured with color Doppler ultrasound.The end-diastolic peak (Vd),systolic peak velocity (Vs),mean blood flow velocity (Vm),systolic peak velocity and peak end-diastolic velocity ratio ( S/D) ,resistance index ( RI) ,pulse index ( PI) ,systolic acceleration time ( AT) blood flow were calculated.Results Renal artery blood flow parameters of normal children had a good correlation with the surface area ( BSA) .Vd,Vs,Vm had a positive correlation with BSA (all P <0.05), and S/D,RI,PI had a inverse correlation with BSA (all P <0.05).Comparison of different classified renal artery blood flow parameters of Vd,Vs,Vm,S/D,RI,PI showed statistically significant differences ( P <0.05),magnetic resonance imaging (MRI),SA,ILA presented a decreasing trend and there was no statistical difference in AT comparison ( P >0.05).Conclusion The result of Doppler ultrasound during normal pediatric renal artery blood flow parameter measurement has a good correlation with BSA of children and can provide reference for clinical diagnosis and treatment of kid-ney disease in children.
