Table 1 Risk, Injury, Failure, Loss and End-stage Kidney (RIFLE) classification [7].

From: Acute kidney injury in severe trauma assessed by RIFLE criteria: a common feature without implications on mortality?

Class Glomerular filtration rate criteria Urine output criteria
Risk Increased SCreat ×1.5 or GFR decrease >25% <0.5 ml/kg/hour × 6 hours
Injury Increased SCreat ×2 or GFR decrease >50% <0.5 ml/kg/hour × 12 hours
Failure Increased SCreat ×3 or GFR decrease >75% or SCreat ≥ 4 mg/dl <0.3 ml/kg/hour × 24 hours, or anuria × 12 hours
Loss Persistent acute renal failure = complete loss of kidney function > 4 weeks
End-stage kidney disease End-stage kidney disease > 3 months
