Primary outcomes

compare the incidence of acute kidney injury

Time frame: Change of Indexes of renal function including SCr, cystatin C, creatinine clearance from 24 hrs before operation to postoperative day (POD) 5.

The diagnostic criteria for AKI is followed by AKIN criteria (absolutely increase in the SCr concentration ≥ 0.3 mg/dL from baseline, ≥ 50% increase in the SCr concentration within 48 hours after operation).
