Comparison of complete blood count (CBC) and renal function during the perioperative period. The postoperative renal function, including sCr (a) and Ccr (b), deteriorated insignificantly, followed by a remarkable improvement to the baseline level. Significant but transient increase of white blood cell count (c) as well as decrease of hemoglobin (d) was observed on POD1, compared with pre-SBES, and was restored to the baseline level on POD7. sCr, serum creatinine; Ccr, creatinine clearance rate; WBC, white blood cell count; HG, hemoglobin; POD, postoperative day. *Indicates statistically significant difference.
