Clinical outcome of kidney transplantation from deceased donors with acute kidney injury by Acute Kidney Injury Network criteria

Purpose: In this study, we investigated the outcome of kidney transplantation (KT) from deceased donors with acute kidney injury (AKI), as defined by the Acute Kidney Injury Network criteria. Methods: Of 156 deceased donors, kidneys from 43 donors (27.6%) with AKI were transplanted into 57 recipients (AKI group). Another 147 recipients received kidneys from donors without AKI (non-AKI group). We compared the incidence of delayed graft function, allograft function for 1 year after KT, and long-term (5 and 10 years) graft survival rate between the 2 groups. Results: Delayed graft function developed more frequently in the AKI group than in the non-AKI group (42.1% vs 12.2%; P < .05), and allograft function-assessed by the modification of diet in renal disease equation-showed a significantly deteriorating pattern at 2 weeks and 1, 3, and 6 months after KT compared with that in the non-AKI group (P < .05 for comparisons at each time point). However, allograft function at 12 months after KT and the long-term allograft and patient survival rates did not differ between the AKI and non-AKI groups. Conclusions: In KT from deceased donors, the AKI group that received kidneys with AKI, as defined by the Acute Kidney Injury Network criteria, showed a higher delayed graft function rate and lower allograft function for 6 months after KT but no effect on allograft function 1 year after KT and on long-term allograft survival.
