BackgroundThe increased number of patients undergoing transplantation has increased the number of transplant recipients undergoing total hip replacement arthroplasty (THRA). We have evaluated the association between transplantation and acute kidney injury (AKI) in patients undergoing THRA.MethodsPatients who underwent THRA from May 2004 to February 2012 were retrospectively assessed. Their demographic and clinical characteristics, the results of perioperative laboratory tests, the amounts of fluids transfused during surgery, and anesthesia time were evaluated. Patients were divided into 2 groups: transplant (n = 222) and nontransplant (n = 2,044) patients. With use of the maximal Acute Kidney Injury Network criteria, AKI was evaluated by changes in creatinine concentration within 48 hours of THRA. Propensity analyses and logistic regression were performed to evaluate the association between transplantation and postoperative AKI.ResultsPostoperative AKI was significantly associated with transplantation (P < .0001), and transplantation was an independent factor predictive of postoperative AKI (P < .0001).ConclusionsTransplant recipients are at risk for AKI following THRA. The mechanism by which organ transplantation enhances postoperative AKI warrants further evaluation.Copyright © 2013 Elsevier Inc. All rights reserved.
