Background: Kidney transplantation is the preferred treatment for endstage renal failure. Unfortunately, donor organ shortages prevent many individuals receiving a renal transplant and there is a need to increase the pool of appropriate donors. The presence of acute kidney injury (AKI) in deceased donors has traditionally been a relative contraindication to renal transplantation, even though renal recovery may be favorable in the absence of chronic renal disease. Methods: We undertook an 8 years retrospective observational study of potential deceased organ donors with AKI requiring renal replacement therapy (RRT). We evaluated the rate of successful transplantation as well as short term and outcomes at a median of 19.5 (13.0–52.7) months after donation. Results: Amongst 1058 consented potential organ donors, 39 patients had AKI requiring RRT, of which 19 became donors (13 not medically suitable, 7 did not proceed to donation). The median (interquartile range (IQR)) donor age was 41 (34–50) years and norepinephrine, epinephrine and vasopressin were given to 18, 14 and 9 donors, respectively. From the 38 donated kidneys 34 were transplanted. The median (IQR) age of recipients was 53 (42.8–58.5) years and they were dialysis free in a median (IQR) of 5.5 (2.3–10.8) days. Only minor abnormalities were found at 3 and 6 months renal biopsies, and two patients experienced graft failure in the first 12 months. Conclusion: Amongst deceased donors with AKI receiving RRT and vasoactive medications outcomes of renal transplantation seems acceptable in the absence of pre-existing renal failure and other donor co-morbidity. Such patients may be an important additional source of kidney donation
