The Doppler-based resistive index and semiquantitative evaluation of renal perfusion using color Doppler failed to discriminate renal recovery patterns in a recent study. The influence of operator experience on resistive index and semiquantitative evaluation of renal perfusion performances is however unknown. This study aimed at evaluating the performance of resistive index and semiquantitative evaluation of renal perfusion according to the operator experience to predict short-term renal prognosis in critically ill patients.

基于多普勒的阻力指数和半定量肾脏灌注根据操作者经验预测持续性急性肾损伤的性能：前瞻性多中心研究的事后分析。

在最近的一项研究中，基于多普勒的阻力指数和使用彩色多普勒对肾脏灌注的半定量评估未能区分肾脏恢复模式。然而，操作者经验对阻力指数和肾脏灌注性能半定量评估的影响尚不清楚。本研究旨在根据操作者的经验评估阻力指数和半定量评估肾脏灌注的性能，以预测危重患者的短期肾脏预后。
