A kidney transplant does not last for ever. The average life-span of a transplanted kidney is twelve years for a deceased donor kidney, and about 15 years for a living related transplant. The average for a living unrelated transplant is somewhere between the two.

With the use of current immunosuppressive medications the risk of sudden kidney rejection is low, and if it occurs it can be treated very effectively. Kidney transplants last relatively long. Fifty percent of kidneys from a living donor still function after 16 to 20 years, and with organs from deceased donors, a transplanted kidney should last 8 to 10 years. Most people who have had a kidney transplant die with a functioning kidney -- the cause of death is usually another disease or illness.
