How many years does a kidney transplant last?

Many years: Depends.. If from living donor, about 90% last five years, 75% last about ten years and nowadays, more and more last more than 20 years if from deceased donor, subtract about 10%-15% from the above numbers. This assumes a decent match and proper attention to taking transplant medications.

Depends: The average functional life of a kidney graft following a transplant depends on the source of the organ. For kidney grafts donated by living-related (and even living-unrelated) donors, the half-life (the time it takes for half of the kidney grafts to fail) is close to 20 years. For kidneys procured from deceased (cadaveric) donors, the half life is approximately 11 years on average.

Varies: Impossible to predict for a given patient. In general living donor kidneys have a half life (50% graft lost) of 18-20 years.

Depends on source: It depends on the donor source and ages of the donor and recipient. About 90% of all kidney recipients are alive with a functioning graft at 1 year. Approximately 55% of living kidney recipients and 40% of deceased donor kidney recipients are alive with a functioning graft at 10 years. Some kidneys have lasted over 30 years.
