Should we discard the graft? Analysis of the renal grafts with a total ischemia time of more than 24 hours donated after cardiac death.
The objective is to investigate the outcome of transplantation using kidney grafts from donors after cardiac death (DCDs) with a total ischemia time (TIT) longer than 24 h. All 373 kidneys were procured from DCDs. They were procured using the in-situ regional cooling technique. Grafts were classified into two groups according to TIT. Fifty-three grafts had a TIT longer than 24 h (group 1), and the other 320 grafts (group 2) were less than 24 h. The numbers of never functioning grafts (PGF) were 3 in group 1 (5.7%) and 17 in group 2 (5.3%), a nonsignificant difference. Graft survival rates at 3, 5 and 10 years posttransplant were 84.9%, 73.0% and 64.1% in group 1, and 76.3%, 69.9% and 57.1% in group 2, which demonstrate no significant difference. The significant risk factors for graft failure were donor age, serum creatinine level on hospitalization and WIT. However, TIT longer than 24 h was not employed. Multivariate logistic regression indicated that only WIT was associated with an increase in the risk of PGF. Our results demonstrate that kidneys from DCDs, even if their TIT is more than 24 h, should be considered a worthwhile source of renal grafts.
