Kidney donation for people with kidney stones
Can I donate a kidney if I have kidney stones?
Each transplant center has its own rules about who can donate. Usually, you can’t be a kidney donor if you:
- Currently have symptoms of kidney stones
- Have passed kidney stones repeatedly in the past
You may be able to donate if you passed 1 stone a long time ago and don’t have any current symptoms of kidney stones.
Tell your doctor if you:
- Have had kidney stones
- Might have had kidney stones, but it wasn’t clear what happened
How do I find out if I have kidney stones?
During your evaluation, your doctors will use imaging tests (such as a CT scan) to see if you have any kidney stones that aren’t causing symptoms.
If you have kidney stones but no symptoms, your doctors may do extra tests to:
- Learn more about the stones
- Measure your chance of getting more stones in the future
- Decide if it’s safe for you to be a donor
If I have small kidney stones and no symptoms when I donate, will I get more kidney stones later?
In one study, people who had small kidney stones but no symptoms when they donated a kidney had a 0-2% chance (2 in 100, or less) of getting more kidney stones after 2 years. This is much less than non-donors who have small kidney stones but no symptoms – these people have a 25% chance (1 in 4) of getting kidney stones.
Some doctors think kidney donors have fewer problems with kidney stones because the donation screening keeps out people who are more likely to get kidney stones again.
How does kidney donation affect chances of getting kidney stones?
There doesn’t seem to be a big effect. In one study, kidney donors and healthy non-donors had about the same:
- Need for surgery for kidney stones
- Hospital visits for kidney stones
- Medical treatment for kidney stones
