| Stage | Serum creatinine | Urine output |
|---|---|---|
| 1 | 1.5–1.9 times baseline, OR ≥0.3 mg/dl (≥26.5 µmol/l) increase |
<0.5 ml/kg/h for 6–12 h |
| 2 | 1.0–2.9 times baseline | <0.5 ml/kg/h for ≥12 h |
| 3 | 3.0 times baseline, OR SCr ≥4.0 mg/dl (≥353.6 µmol/l), OR Initiation of renal replacement therapy, OR eGFR <35 ml/min per 1.73 m2 (<18 years) |
<0.3 ml/kg/h for ≥24 h, OR Anuria for ≥12 h |
SCr, serum creatinine; eGFR, estimated glomerular filtration rate.
