A pilot study of the Doppler renal arterial flow pattern was done in a group of 38 normal children, including 11 neonates age 2 weeks or less, 10 infants age 2 weeks to 1 year, and 17 children age 1 year and over. The appearance time, acceleration time, end-diastolic to peak-systolic velocity ratio (d/S), and diastolic to systolic flow ratio (A2/A1) increased with age. Another four patients with acute renal failure showed a characteristic absence of blood flow in the whole or late-diastolic phase. Diastolic flow reappeared with recovery. Doppler renal arterial flow pattern may be a noninvasive investigation of diagnostic and prognostic value.
对38名正常儿童进行了一项关于多普勒肾动脉血流模式的初步研究，其中包括11名2周龄及以下的新生儿、10名2周龄至1岁的婴儿以及17名1岁及以上的儿童。血流出现时间、加速时间、舒张末期与收缩期峰值速度比值（d/S）以及舒张期与收缩期血流比值（A2/A1）均随年龄增长而增加。另外4例急性肾衰竭患者表现出在整个舒张期或舒张晚期无血流的特征性表现。随着病情恢复，舒张期血流重新出现。多普勒肾动脉血流模式可能是一项具有诊断和预后价值的无创检查。
