ObjectivesHigh terminal serum creatinine level in a deceased donor has been reported as the second most frequent cause of refusal for kidney transplantation. A growing body of evidence has shown a comparable outcome of kidney transplantation from deceased donors with acute kidney injury (AKI). However, the influence of the severity of AKI on graft outcomes remains to be elucidated.MethodsIn this retrospective cohort study, 84 consecutive kidney transplants from 57 standard-criteria donors were classified into 4 groups by RIFLE (Risk, Injury, Failure, Loss of function, and End-stage renal disease) classification according to donor AKI severity before kidney procurement. The donor and recipient characteristics and graft outcomes were compared.ResultsOf 84 kidney transplants, 56, 11, 10, and 7 recipients were in the Non-AKI, Risk, Injury, and Failure groups. The mean terminal creatinine was 1.1, 1.6, 2.3, and 4.4 mg/dL in these 4 groups. However, the graft outcomes, including primary nonfunction rate, delayed graft function rate, acute rejection rate, renal function, graft survival and overall survival over the first 5 years had no statistical difference. A trend toward increasing delayed graft function rate as the severity of AKI increased was observed (Non-AKI, Risk, Injury, and Failure: 26.8%, 36.4%, 60.0%, and 57.1%, P = .099).ConclusionsOur study demonstrates that AKI before procurement does not cause adverse long-term graft outcomes. Standard-criteria donors with AKI are suitable for kidney transplantation, even with a high severity of AKI.Copyright © 2014 Elsevier Inc. All rights reserved.
