How long a transplant lasts depends on the original disease, the condition of the patient as they receive it, the age, etc. Currently we see that transplants from living donors will have about 85-90% function rate at 5 years, and we have a hard time figuring out what the time is for half of them to not be functioning, since the new drugs are so much better, but have only been available in the last 10-20 years. SO much better than in the 1970's and 1980's!!
