Multivariate logistic regression analysis showed that positive preoperative urine culture (PUC+) (OR = 2.331, P = 0.044), procalcitonin (PCT) (OR = 1.093, P = 0.037), C-reactive protein (CRP) (OR = 1.017, P < 0.001), and neutrophil ratio (NEUT%) (OR = 1.091, P = 0.004) of postoperative were independent predictors of SIRS, and PCT (OR = 1.017, P = 0.003) and CRP (OR = 1.080, P < 0.001) were independent predictors of urosepsis. This evidence concerns the gene CRP and systemic inflammatory response syndrome.
