BACKGROUND: As the disparity between the numbers of available organ donors and patients awaiting transplantation increases, different strategies have been proposed to extend the donor pool. Patients with acute kidney injury (AKI) developing during an intensive care unit (ICU) stay are often considered to be donors, but the long-term outcomes of such high-risk kidney transplantations is unknown. We analyzed the renal function and outcomes over 5 years of kidney grafts recovered from deceased donors diagnosed with AKI. MATERIALS AND METHODS: We collected data from 61 deceased kidney donors, identified in 1 ICU, and 120 kidney graft recipients who underwent transplantation between January 1999 and December 2006. Donors were stratified according to the RIFLE classification, based on their creatinine and urine output change from admission to the ICU and organ procurement. Recipient kidney graft function (eGFR) calculated according to the MDRD (Modification of Diet in Renal Disease) equation was estimated every 6 months. RESULTS: Among 61 donors, 10 (16.4%) developed AKI, including 7 classified as "risk", 2 as "injury," and 1 as "failure." The mean follow-up of kidney graft recipients was 49±18 months. The long-term risk for graft loss was significantly higher among the group of kidneys recovered from donors with AKI (27.8% vs 7.1%; P=.02; log-rank=0.07). Their excretory function was worse over the whole follow-up period. CONCLUSION: Patients with kidney grafts obtained from the donors with AKI showed a higher risk for graft loss and worse excretory function upon long-term follow-up.
