Ralib et al. report that urine output (UO) <0.3 ml/kg/h for >6 h predicts a composite outcome of mortality and dialysis requirement in critically ill patients. Their findings validate UO as a marker of acute kidney injury, but raise the question of whether the diagnostic thresholds should be more stringent.
