In the multivariate analysis of the variables whichwere found statistically significant in univariate analysis associated withpostoperative AKI, increased serum creatinine (P=0.0001), CRPlevels (P=0.02), PLR (P=0.002) and NLR(P=0.04) in the preoperative period, increased leukocyte counts(P=0.03), CRP levels (P=0.02), NLR(P=0.002) and PLR (P=0.01) in the firstpostoperative day and prolonged intubation time (P=0.006) werefound as independent predictors of early postoperative AKI. Here, CRP is linked to acute kidney injury.
