Schematic diagram of the study work flow. Between January 2008 and May 2016, 94 donors underwent donor nephrectomy at our institution. Nineteen donors were excluded because of insufficient radiographic and laboratory data, and the data from 75 remaining donors were included in our retrospective study. We evaluated preoperative basic clinical information, abdominal adipose tissue parameters, and nutritional status, and donors were divided into 2 groups according to VAT area at L4–5 (VAT area <80 and ≥80). Renal function 12 months after donor nephrectomy was compared between the 2 groups, and prognostic factors for development of chronic kidney disease of stage G3b at 12 months after donor nephrectomy were identified by logistic regression analysis. Follow-up data 24 months after donor nephrectomy were available for 53 out of out of the 75 donors, and thus renal function 24 months after donor nephrectomy was also compared between the 2 groups.
