Living Organ Donors

Donating an organ may be the most deeply satisfying thing you’ll ever do. On average, 20 people die each day while waiting for an organ transplant. Through the unique gift of living organ donation, you offer a second chance at life to someone who is struggling to survive.

Learn how living donation works and how it has changed the lives of donors, recipients and care teams at UCSF.

Kidney Donation

When you donate a kidney, your remaining kidney enlarges slightly and begins performing the same amount of work as your previous pair. Living kidney donors have the same life expectancy, general health and kidney function as non-donors.

Liver Donation

Livers have the unique ability to regenerate. When you donate part of your liver, what remains grows back to its original size within weeks. Having a living donor decreases the time a patient waits for a transplant and increases the chances of a successful transplant.

Why donate a kidney to a stranger?

If you want to donate to someone you know but aren't a good match due to incompatible blood types, you can still donate and help your friend or loved one get a kidney from a different donor. UCSF can help by arranging a process called a paired exchange, which involves two recipients with willing but incompatible donors. If the recipient from one pair is compatible with the donor from the other pair, and vice versa, the transplant center arranges a "swap," in which the patients receive a kidney from the other person's donor. Read more about paired exchanges

A single altruistic donor – someone who decides to donate a kidney to a stranger rather than a relative or friend – can also set off a "transplant chain," in which many such exchanges are arranged. Like eHarmony for organs, software matches willing donors with compatible patients awaiting transplant. Through transplant chains, a single altruistic donor can benefit many lives across the country.
