title: Acute kidney injury after radical gastrectomy: a single center study.
abstract: OBJECTIVE
  To investigate the incidence of acute kidney injury (AKI) and identify risk factors for AKI in patients who undergo radical gastrectomy.
  
  
  METHODS
  This study included 536 patients underwent radical gastrectomy. Primary outcome was AKI, defined as a ≥ 50 % increase in serum creatinine relative to baseline during the first three postoperative days. Secondary outcomes were duration of hospitalization and all-cause hospital mortality within 30 days after radical gastrectomy.
  
  
  RESULTS
  A total of 37 (6.9 %) patients developed postoperative AKI. Age, body mass index (BMI), presence of hypertension, hyperlipidemia, poor blood glucose control, and preoperative higher cystatin C were associated with increased frequency of AKI. By multivariable analyses, the independent risk factors for AKI were age, BMI, hypertension, hyperlipidemia, and preoperative cystatin C.
  
  
  CONCLUSIONS
  Postoperative AKI is not infrequent after radical gastrectomy. Age, BMI, hypertension, hyperlipidemia, and preoperative cystatin C are independently associated with increased risk of postoperative AKI.
