GALLEGO VALCARCE, E. et al. Short cold ischemia time optimizes the results of renal transplantation performed with expanded criteria donors. Nefrología (Madr.) [online]. 2009, vol.29, n.5, pp.456-463. ISSN 1989-2284.

Introduction: Outcome of renal transplant from expanded criteria donors (ECD) is usually inferior than those from standard criteria donors (SCD) and may be improved decreasing cold ischemia time (CIT) and minimizing preservation injury. We compare the results obtained with CIT < 15 hours in kidney transplants from ECD vs. SCD. Subjects and Methods: Prospective, single center study of kidney transplants performed since June 2003 to December 2007. Minimum follow-up period was 12 months. Data of donors, receptors and transplant outcome from ECD and SCD are compared. Results: CIT (mean ± SD) was 9.3 ± 2.5 hours in transplants from ECD (n = 24) and 8.3 ± 3.3 hours in those from SCD (N = 50), p = 0.18. We did not find significant differences among recipients of grafts from ECD and those from SCD regarding: primary non-function (4.2% vs. 2%, respectively), delayed graft function (16.7% vs. 10%), surgical complications (25% vs. 16%) or acute rejection episodes (8.3% vs. 2%). Glomerular filtration rate at one year follow-up was 65.8 ± 14.9 ml/min in ECD recipients and 49.4 ± 12.5 ml/min (p < 0.0001). One year graft survival was 95.8% in ECD recipients and 94% in SCD recipients (p = 0.75). Conclusions: Short CIT in kidney transplant from ECD leads to similar outcome than that obtained from SCD, although renal function is inferior in ECD grafts.
