5 essential facts about living kidney donation

Kidneys are crucial for staying healthy. They filter toxins, balance minerals and even produce hormones. But when they fail, patients feel exhausted, lose their appetite and can get seriously ill.

Dialysis, a treatment that performs the core functions of the kidneys, can help. But it’s hard on patients, and it isn’t a permanent fix. A kidney transplant is the best long-term solution.

Ordinary people have the power to save a life. That’s because a kidney, unlike a heart or lung, can be donated by someone who is alive. (Individuals with two healthy kidneys can enjoy full, normal lives after giving one to someone else).

At the University of Chicago Medicine kidney transplant program, I work with our patients to help them understand living kidney donation. Here are five key facts about the process:

1. Living kidney donation saves lives — and shortens the wait

It’s hard to believe, but more than 90,000 people in the U.S. are waiting for a kidney transplant.

Unfortunately, there aren’t enough kidneys available, which means many people wait years.

Living donation is a game-changer. It shortens or even eliminates the wait and offers recipients their best chance of survival and quality of life for the future.

2. Living-donor kidney transplants are the gold standard for patients

Kidneys from living donors are healthier and more effective than those from deceased donors. When you donate a kidney while you’re alive, the organ is transplanted quickly — often within hours — making it more likely to work well right away and minimizing complications.

Recipients also benefit from knowing their donor, which adds an extra layer of trust and comfort.

3. Donor health and safety are always the top priority

Deciding to donate a kidney is a big commitment. Transplant teams are dedicated to making sure you’re prepared and protected. You’ll undergo comprehensive evaluations to ensure you are physically and mentally healthy.

A donor also has an independent advocacy team with nephrologists, social workers and physicians. Their job: to ensure you’re making the choice freely without pressure or coercion. Hospitals may offer reimbursement for donation-related travel, lodging or even lost wages.

4. Healthy adults from all backgrounds can make a difference

If you’re 18 or older, healthy and ready for a remarkable act of generosity, you could be a living kidney donor. Donors may be close family members or friends of the recipient — or complete strangers. At UChicago Medicine, you can take a simple questionnaire to see if you’re ready.

The waiting time for a kidney transplant can stretch to five to eight years, during which a patient’s health may decline. Having someone step up as a living donor can dramatically reduce that wait, giving patients a second chance much sooner.

5. The donation process is safe, minimally invasive and inclusive

Thanks to advances in minimally-invasive techniques, most donors leave with a tiny bandage over their belly button, with the incision practically hidden inside it. Recovery is fast; most donors go home the next day.

If you and your recipient aren’t a match, paired kidney exchange (PKE) programs let you donate to someone else, while your loved one receives a kidney from a different donor. Organizations like the National Kidney Registry (NKR) and the Alliance for Paired Kidney Donation can help find the best match for all parties.

What happens to living donors after they donate their kidney?

The donor experience doesn’t end at surgery. Transplant centers support donors with check-ups immediately after surgery, six months later and at the one- and two-year marks to ensure ongoing good health.

Many donors report feeling proud and fulfilled, knowing they made a lasting difference.
