OBJECTIVE To investigate whether patients requiring dialysis are a higher risk surgical population and would experience more perioperative adverse events even when undergoing a perceived less invasive operation as a laparoscopic radical nephrectomy (LRN). LRN is generally a well-tolerated surgical procedure with minimal morbidity and mortality. Prior to transplantation, dialysis patients will often have to undergo a LRN to remove a native kidney with a suspicious mass.; MATERIALS AND METHODS Patients in the American College of Surgeons National Surgical Quality Improvement Program who underwent a LRN between 2011 and 2016 were included. Patients were stratified by the need for preoperative dialysis 2 weeks prior to surgery, and perioperative outcomes were compared. A multivariable logistic regression analysis was performed to test the association between the need for preoperative dialysis and perioperative risk.; RESULTS There were 8315 patients included in this analysis of which 445 (5.4%) patients required preoperative dialysis. Patients who required preoperative dialysis had more minor (P <.0001) and major (P = .0025) complications, a higher rate of return to the operating room (P = .002), and a longer length of stay (P <.0001) than those patients not requiring preoperative dialysis. In a multivariate analysis, the need for preoperative dialysis was independently associated with adverse perioperative outcomes (OR= 1.45, CI = 1.08-1.95, P = .015).; CONCLUSION Patients requiring preoperative dialysis were more likely to experience a perioperative complication and have a longer length of stay. For LRNs performed prior to transplantation, further risk stratification is needed, and treatment sequencing may need to be reconsidered. (C) 2018 Elsevier Inc.
