Study: Kidney donors do fine, no long-term issues

NEW YORK (AP) — Donating a kidney doesn't appear to have any long-term health consequences for the donor, a reassuring study shows. Researchers at the University of Minnesota found those who gave up one of their two kidneys lived a normal life span and were as healthy as people in the general population. The donation also didn't raise the risk of having kidney failure later.
Kidney donation has generally been considered safe, although with surgery, there are always risks. The new research of nearly 3,700 donors dating back more than four decades is the largest and longest study to look at long-term outcomes, said the researchers. They reported their findings in Thursday's New England Journal of Medicine.
"It is a confirmation that living donation is a safe thing," said Dr. Matthew Cooper, a transplant surgeon at the University of Maryland, who was not involved in the research....
Dr. Hassan Ibrahim, the study's leader, and his colleagues wanted to find out what happened to the 3,698 people who had donated a kidney at the university since 1963. They tried to contact everyone and used government records to find out who had died. A group of 255 donors was randomly selected to have kidney and other tests. Results were compared with health outcomes for the general population.
Overall, 268 of the donors died, which the researchers said was comparable to survival in the general population. Eleven donors developed kidney failure decades later and needed dialysis or a transplant. The researchers said the rate of kidney failure in the donors was lower than that reported in the general population.
Most of the donors tested had good kidney function and reported an excellent quality of life, the study found.
The good outcomes likely reflect the strict criteria used to pick the donors, the researchers said. The donors had to be healthy with no kidney problems, and be free of high blood pressure and diabetes — two main causes of kidney disease.
Ibrahim said he hopes the results will increase donations and encourage transplant centers to continue to carefully select donors and not relax their requirements.
