Answer

A report by the AKIN proposed the following criteria for AKI [8, 9] :

  • Abrupt (within 48 h) reduction in kidney function currently defined as an absolute increase in serum creatinine of 0.3 mg/dL or more (≥26.4 μmol/L) or

  • A percentage increase in serum creatinine of 50% or more (1.5-fold from baseline) or

  • A reduction in urine output (documented oliguria of < 0.5 mL/kg/h for >6 h)
