Living kidney donation and the chance of kidney failure
If I donate a kidney, will I have a higher chance of developing kidney failure?
If you donate a kidney, you will have about a 1% chance of developing kidney failure (end stage renal disease). This is a higher rate than if you had not donated.
However, a donor’s chance of kidney failure is still low. This is due to the careful screening process for donors that excludes persons with risk factors for kidney disease. A recent study of nearly 100,000 living donors found these lifetime chances of getting kidney failure, from highest to lowest chance1:
- General population = 3.2% chance
- Kidney donors = .9% chance
- Healthy non-donors = .14% chance
What happens if a donor develops kidney failure?
If a donor develops kidney failure, they will need to get care from a nephrologist who will discuss treatment options including dialysis and transplant. If a donor is placed on the transplant waiting list, they receive priority points.
A tool to help estimate your chances
There is a tool called a ‘risk calculator’ that may help people with 2 kidneys understand their chances of getting kidney failure2. You can find it at: http://www.transplantmodels.com/esrdrisk/
But risk calculators are not perfect and may underestimate the chance of kidney failure in some groups, such as children and adolescents, and people with a family history of kidney disease.
Because kidney donors have 1 kidney, the chance for donors is likely higher than these estimates.
How can I learn more?
Talk to your donor team to learn more about your chances of kidney failure and other specifics of your situation.
