Abstract

Abstract Survival after kidney transplantation is better than on the waiting list, even in the elderly. However, the effects of a prolonged waiting time for an organ on death with graft function have not been critically examined in this patient group. We conducted a single-center retrospective analysis of our cadaveric renal transplant experience in patients older than 60 years who received a kidney between January 1, 1990 and December 31, 2003. Besides waiting time, the effects of recipient age, gender, and diabetes were also examined. Cox proportional hazards analysis using patient death as a time-dependent outcome was used to estimate the hazard ratio of death posttransplantation. Using Kaplan-Meier survival methodology, patients with waiting times ≤5 years had significantly better survival times posttransplantation compared with those with waiting times >5 years (6.2 vs 2.8 years; P < .001). Each year of waiting was associated with hazard ratio 1.16 (95% confidence interval [CI], 1.06–1.27) for death. Prolonged waiting time on dialysis is deleterious to patient survival in recipients older than 60 years at transplantation. Early transplantation thus should be strongly encouraged in this group of patients.
