About 25 percent of healthy people have abnormalities in the kidneys and their blood vessels, but most of these abnormalities aren't serious enough to prevent a person from donating a kidney, a new study shows.
More research is needed to determine how these abnormalities affect long-term health, the study authors noted.
In the study, researchers conducted CT scans of the kidneys and renal arteries of nearly 2,000 adults at the Mayo Clinic who volunteered to donate a kidney to a patient with kidney failure. The results showed that at least one-quarter of the potential donors had abnormalities. The most common problem was kidney stones, which were present in about 10 percent of the participants.
