Prolonged cold ischaemic time (CIT) is associated with delayed initial graft function and may also have a negative impact on long-term graft outcome. We carried out a study comparing the long-term graft survival rates between those recipients who received the first of a pair of donor kidneys versus the recipient of the second graft. Adult kidney transplant recipients who received one of a pair of donor kidneys at our institution between 1989-1995 were included. All recipients received a cyclosporin based immunosupression regimen. Graft survival rates were compared between the 2 groups at 1-, 3-, 5- and 10-year intervals. A total of 520 renal transplant grafts were included in this study. Mean donor age was 35.4 years. Groups were similar for recipient age, gender, number of HLA mismatches, transplant number for that patient and percentage PRA. CIT was the only variable that was significantly different between the two groups; mean of 19.93 h in the first group compared to 25.65 h in the second group. Graft survival rates for the first kidney were significantly better than the second kidney-graft survival at 1 year 88.5% versus 84.7%, at 3 years 81.8% versus 76.7%, at 5 years 72.2% versus 64.9% and at 10 years 55.2% versus 40% (p = 0.012). Patient survival rates were similar in both groups. In our experience, the long-term graft survival rates are significantly better for the first kidney transplanted compared to the second kidney.
