Background This study was designed to compare donors who underwent open (ODN) versus retroperitonoscopic nephrectomy (RDN) in terms of intra-operative oxidative stress and recipients graft function in the early postoperative period. Methods Among 40 patients who underwent donor nephrectomy, 23 were operated via an open method and 17 via retroperitonoscopic method. To analyze oxidative stress, we measured plasma levels of malondialdehyde (MDA), protein carbonyl, and protein sulfhydryl moieties in donor venous blood before induction of anesthesia and postoperatively at 0, 6, and 24 hours. The influence of oxidative stress on graft function was evaluated by means of the postoperative 5th day recipient creatinine and estimated glomerular filtration rate (eGFR) Modification of Diet in Renal Disease Formula (MDRD) to evaluate delayed graft function (DGF) status. Results ODN patients showed significantly higher 24-hour mean levels of MDA, (6,139 ± 1,854 vs 4,813 ± 1,771 nmol/L; P =.01), protein carbonyl (366 ± 64 vs 311 ± 62 μmol/L; P =.01) and protein sulfhydryl (468 ± 110 vs 386 ± 75 μmol/L; P =.01) moieties compared with those RDN patients. However, ODN and RDN recipients were similar in terms of 5th day mean creatinine and eGFR (1.1 ± 0.3 vs 1.4 ± 0.8 mg/dL and 69.15 ± 12.24 vs 56.31 ± 25.2, respectively) and DGF status (4.4% [1/23] vs 5.9% [1/17], respectively). Conclusions Although ODN donors were more prone to intra-operative oxidative stress than RDN donors, based on significantly higher levels of oxidative stress markers, this difference seems to not significantly influence recipients early graft function. © 2013 by Elsevier Inc.
