Living related kidney donors over 60 years old.
The lack of available cadaveric organs for transplantation has resulted in an increased number of kidney transplants from living donors. During a period of 6 years, 149 kidney transplantations were performed from living related donors in our institute, 33.5% of whom were older than 60 years of age. In this study we examined the survival of patients and grafts as well as the graft function in 50 patients with transplants from donors over 60 years (mean age 65 years) as compared with those of 99 patients with transplants from donors younger than 60 years (mean age 47 years). There were no significant differences in the course of donor nephrectomy, postoperative complications, or remnant kidney function. However, delayed graft function occurred more frequently in recipients of transplants from older donors. Improvement in graft function was also slower in recipients of kidneys from older donors, with significant differences in serum creatinine levels observed during the first 12 months after transplantation. More frequent acute complications and more progressive chronic graft failure, irrespective of the causes, occurred during the 1st post-transplant year in recipients with grafts from older donors. Five-year patient survival (77% vs 92%) and kidney graft survival differed significantly for the same period with worse results for patients receiving grafts from older donors. It may be concluded that kidney grafts from donors older than 60 years -- and especially those older than 70 years -- may be used for living related kidney transplantation, but with precautions.
