Acute renal injury after partial hepatectomy

Table 1 Current diagnostic criteria for acute kidney injury in general population

	RIFLE criteria[27]	AKIN criteria[28]	KDIGO criteria[29]
Diagnostic criteria	Increase in SCr to ≥ 1.5 times baseline, within 7 d; or GFR decrease > 25%; or urine volume < 0.5 mL/kg per hour for 6 h	Increase in sCr by ≥ 0.3 mg/dL (26.5 mmol/L) within 48 h; or increase in sCr ≥ 1.5 times baseline within 48 h; or urine volume < 0.5 mL/kg per hour for 6 h	Increase in sCr by ≥ 0.3 mg/dL (26.5 mmol/L) within 48 h; or increase in SCr to ≥ 1.5 times baseline, which is known or presumed to have occurred within the prior 7 d; or urine volume < 0.5 mL/kg per hour for 6 h
	Risk: sCr increase 1.5-1.9 times baseline; or GFR decrease 25%-50%; or urine output < 0.5 mL/kg per hour for 6 h	Stage 1: sCr increase 1.5-1.9 times baseline; or sCr increase ≥ 0.3 mg/dL (26.5 mmol/L); or urine output < 0.5 mL/kg per hour for 6 h	Stage 1: sCr increase 1.5-1.9 times baseline; or sCr increase ≥ 0.3 mg/dL (26.5 mmol/L); or urine output < 0.5 mL/kg per hour for 6-12 h
Staging	Injury: sCr increase 2.0-2.9 times baseline; or GFR decrease 50%-75%; or urine output < 0.5 mL/kg per hour for 12 h	Stage 2: sCr increase 2.0-2.9 times baseline; or urine output < 0.5 mL/kg per hour for 12 h	Stage 2: sCr increase 2.0-2.9 times baseline; or urine output < 0.5 mL/kg per hour for ≥ 12 h
	Failure: sCr increase ≥ 3.0 times baseline: or GFR decrease 50%-75%; or sCr increase ≥ 4.0 mg/dL (353.6 mmol/L) with an acute increase of at least 0.5 mg/dL (44 mmol/L); or urine output < 0.3 mL/kg per hour for ≥ 24 h; or anuria for ≥ 12 h	Stage 3: sCr increase 3.0 times baseline; or sCr increase ≥ 4.0 mg/dL (353.6 mmol/L) with an acute increase of at least 0.5 mg/dL (44 mmol/L); or urine output < 0.3 mL/kg per hour for ≥ 24 h; or anuria for ≥ 12 h	Stage 3: sCr increase 3.0 times baseline; or sCr increase to ≥ 4.0 mg/dL (353.6 mmol/L); or initiation of renal replacement therapy; or urine output < 0.3 mL/kg per hour for ≥ 24 h; or Anuria for ≥ 12 h
