BACKGROUND: The need for organs for renal transplantation has encouraged the use of grafts from increasingly older donors. Earlier studies performed in Spain have shown the suitability of donors aged 60-65 years. In this single-center study, we evaluated our results using donors >70 years old. METHODS: We evaluated 401 primary transplantations performed from January 2000 to December 2009. Their initial immunosuppression was a tacrolimus-based (n = 324), cyclosporine-based (n = 70) or calcineurin inhibitor-free (n = 7) regimen patients. Recipients were classified according to the donors age: <50 (42.6%); 50-70 (39.7%) and >70 (17.5%) years. RESULTS: There were no differences in recipient or donor gender, time on dialysis, cold ischemia, delayed graft function, or acute rejection episodes. However, the mean age was higher among patients who received grafts from donors >70 years old; 42.5 ± 12.4 years for <50, 58.1 ± 8.2 years for 50-70, and 65.7 ± 7.2 years for >70; (P = .000). The serum creatinine at 12 months was increased according to the age of the donor; 1.4 ± 0.6, 1.8 ± 0.6, 70 and 1.7 ± 0.5 mg/dL, respectively (P = .001). The graft survival rates at 5 years were 81%, 74%, and 70%, respectively (P = .519). Upon multivariate analysis only HLA-DR mismatches, delayed graft function, and acute rejection episodes were associated with graft loss. Patient survival rates (86%) at 5 years were similar among recipients from donors aged 50-70 and >70 years, but higher (96%) for those who received a graft from a donor <50 years (P = .003). CONCLUSIONS: Nearly 20% of donors were >70 years old in our study. Their kidneys displayed excellent short-term outcomes.
