What the Kidney Transplant Waitlist Is

The national transplant waitlist is a database of people in the United States who are waiting for an organ transplant, including kidneys. You can only be placed on this list after a transplant center evaluates you and decides you are a good candidate for a kidney transplant.

The waitlist is used only for kidneys from deceased donors. Once you’re listed, you may be matched with a kidney from any deceased donor in the country, as long as it is a good match for your body. While you wait, it’s important to keep your transplant team updated about your health, contact information, and any major life changes so they can reach you when a kidney becomes available.

How Long Does It Take to Get a Kidney?

Once you are on the waitlist, the time to transplant can be very different from person to person. Some people get a call quickly; others wait many years. At many centers, the average wait is around 3–5 years, but it can be shorter or longer depending on:

​

• How long you’ve been on dialysis or on the waitlist

• Your blood type (some are easier or harder to match)

• Where you live and how many donors and recipients are in your region

• Your antibody level (how “picky” your immune system is about foreign tissue)

You can be listed at more than one transplant center (called multi-listing) to increase your chances of getting an offer sooner. Another way to shorten your wait dramatically is to receive a kidney from a living donor instead of waiting for a deceased donor kidney.

​

Different Types of Kidneys on the Waitlist

Not all kidneys from deceased donors are the same. Each organ is evaluated for safety and assigned a score (often called KDPI) that estimates how long it is likely to work.

• Lower KDPI kidneys are expected to last longer and are often a better fit for younger patients or those who have not been on dialysis very long.

• Higher KDPI kidneys may not last as long, but they can still work well and are often a good option for older patients or people who have already waited a long time on dialysis.

Choosing to accept a higher KDPI kidney can sometimes mean getting a transplant sooner and spending less time on dialysis. Your transplant team will talk with you about which types of kidneys make sense for your age, health, and goals.

Staying Healthy While You Wait

Being on the waitlist doesn’t mean you just sit and wait for a phone call. You and your transplant team are working together to keep you as ready as possible for surgery. This usually includes:

• Attending all scheduled doctor and dialysis appointments

• Following a kidney-friendly eating plan

• Taking medications on time

• Keeping up with recommended tests and yearly check-ins with the transplant center

If something comes up that makes surgery too risky for a while—like a serious infection, uncontrolled heart problems, or other issues—your center may temporarily mark you as “inactive.” You still earn waiting time, but you won’t be called for a kidney until you’re healthy enough again, at which point they can reactivate you.

When a Kidney Becomes Available

When a kidney from a deceased donor becomes available, the matching system creates a list of potential recipients based on many factors, including blood type, tissue match, waiting time, and location. If you are high on that list, your transplant center may receive an “offer” for you.

If your team believes the kidney is a good fit, they will call you—often with little warning, any time of day or night. That’s why it’s critical to:

• Keep your phone on and charged

• Make sure the center always has current contact numbers

• Have a simple plan for how you’ll get to the hospital when they call

Sometimes you might be called as a backup in case the first person offered the kidney cannot receive it. Even then, it means you are close, and the team wants you to be ready.

Questions to Ask Your Care Team

Here are some good questions to bring to your nephrologist or transplant team:

• “How long could my wait time be at this center?”

• “Would it help me to be listed at more than one transplant center?”

• “Am I a good candidate for accepting a higher KDPI kidney?”

• “What do I need to do to stay active on the waitlist?”

• “What should I have ready for when I get ‘the call’?”
