Effect of increased donor age on kidney transplant outcome.

Donors over the age of 50 years provided kidneys for 28 of our 226 recipients (12.4%) transplanted from January 1, 1987 to December 31, 1988. Immediate function following transplantation occurred in 36% of the kidneys from donors both over and under the age of 50. The overall 3-month graft survival rate for transplants from donors over 50 years was 89%, compared with 78% for transplants from donors under 50 years (p>0.05). Thus kidneys from well-selected older donors make an important contribution to the total pool of organs available for transplantation.
