Arm Intervention/treatment
Experimental: BIVON group Drug: sodium bicarbonate
BIVON group were received 0.5 mmol/kg of sodium bicarbonate for 1hours after induction of anesthesia and following 0.15 mmol/kg of sodium bicarbonate during the operation.

Placebo Comparator: Placebo group
normal saline infusion
Drug: normal saline

Primary Outcome Measures :
  1. 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).
