Seventeen children with acute renal failure due to the hemolytic-uremic syndrome were examined with duplex Doppler ultrasound. Serial measurements of intrarenal arterial pulsatility were obtained by means of the Pourcelot index. These were compared with daily urine volume, both during the phase of renal failure (during which most of the children were undergoing peritoneal dialysis) and during recovery of renal function. During oliguria or anuria there was either no intrarenal arterial flow (ie, absent Doppler shifts), or absent, reversed, or markedly reduced diastolic flow. Within 24-48 hours after diastolic Doppler shifts returned to normal, diuresis occurred. The Doppler examination enabled prediction of recovery and allowed dialysis treatment to be abbreviated or, in some cases, canceled.
对17例因溶血尿毒综合征导致急性肾衰竭的儿童进行了双功多普勒超声检查。通过普尔塞洛指数对肾内动脉搏动性进行连续测量。将这些测量结果与肾衰竭阶段（在此期间大多数儿童正在接受腹膜透析）及肾功能恢复期间的每日尿量进行比较。在少尿或无尿期间，肾内动脉要么无血流（即无多普勒频移），要么舒张期血流缺失、反向或显著减少。在舒张期多普勒频移恢复正常后的24 - 48小时内，出现利尿。多普勒检查能够预测恢复情况，并可缩短透析治疗时间，在某些情况下甚至可取消透析治疗。
