Renal Graft Function After Prolonged Agonal Time in Non–Heart-Beating Donors

Abstract: To deal with the increasing gap between organ demand and supply for kidney transplantation, many centers have started to use non–heart-beating (NHB) donors. When we initiated our program to utilize kidneys from such donors in 1998, we had no protocol for the maximal agonal period. This however was audited in retrospect. Our current wait time is now a maximum of 5 hours. Concern has been expressed in the past about possible deterioration in the quality of the organs with a protracted agonal time. We aimed in this study to examine the effect of prolonging agonal period on the quality of kidneys retrieved from Maastricht category III donors: A total of 40 kidneys were transplanted from 29 category III donors between 1998 and 2004. Eleven kidneys had donor agonal times of >5 hours; the remainder, agonal times <5 hours. Both groups were matched for donor and recipient factors. The mean glomerular filtration rates at 12 months for <5 hours versus >5 hours agonal time were 43.8 ± 4.4 versus 49.8 ± 5.8, respectively (P = .24) and at 24 months, 46.83 ± 8.99 versus 37.67 ± 3.85, respectively (P = .24). In conclusion, intermediate graft function is comparable to ones with shorter agonal time, although we await long-term results. [Copyright &y& Elsevier]
