Perioperative Use of Serum Creatinine and Postoperative Acute Kidney Injury: an Observational, Monocentric, Retrospective Study to Explore Physicians' Perception and Practice.

The perioperative approach adopted in a cohort of adult oncological patients undergoing major abdominal surgery will be described. In particular, the physician's attitude toward use of sCr for identification of patients at risk for PO-AKI will be described, as well as the patients who should be reassessed in the long term for progression toward CKD. The incidence and risk factors associated with PO-AKI and renal function deterioration within a year postoperatively will be also evaluated.
