The NHS Organ Donor Register

In the UK, consent is required before organs can be donated. A person can give their consent to become an organ donor after death by joining the NHS Organ Donor Register or by discussing their wishes with loved ones.

Alternatively, a person’s organs can be donated if consent is obtained after their death from an authorised person, such as a relative or friend.

The NHS Organ Donor Register is the same in principle as carrying a donor card, but is a failsafe way of ensuring your wishes are made clear. A donor card can be lost or forgotten about, but joining the register will mean there's a permanent record of your wishes that doctors can check in the event of your death.

Joining the NHS Organ Donor Register is quick and simple, and will only take a few minutes of your time. You can remove yourself from the register at any time, and you can specify what you're willing to donate.

A kidney transplant is the transfer of a healthy kidney from one person (the donor) into the body of a person who has little or no kidney function (the recipient).

The main role of the kidneys is to filter waste products from the blood and convert them to urine. If the kidneys lose this ability, waste products can build up, which is potentially dangerous and can be life threatening.

This loss of kidney function, known as end stage chronic kidney disease or kidney failure, is the most common reason for needing a kidney transplant.

It is possible to partially replicate the functions of the kidney using a blood filtering procedure known as dialysis, but this can be both inconvenient and time-consuming so a kidney transplant is the treatment of choice for kidney failure whenever possible.

Who can have a kidney transplant?

Most people who need a kidney transplant are able to have one, regardless of their age, as long as:

  • they are well enough to withstand the effects of surgery
  • the transplant has a relatively good chance of success
  • the person is willing to comply with the recommended treatments required after the transplant – such as taking immunosuppressant medication and attending regular follow-up appointments

Reasons why it may not be safe or effective to perform a transplant include having an ongoing infection (this will need to be treated first), heart disease, liver failure, cancer that has spread to several places in your body (metastatic cancer), and AIDS (the final and most serious stage of an HIV infection).

However, people who have HIV that is being effectively controlled with medication can often have a kidney transplant.

Kidney donations

Unlike many other types of organ donation, it is possible to donate a kidney while you are alive because you only need one kidney to survive. This is known as a living donation.

People who want to be considered as a kidney donor are tested very carefully to ensure they are a suitable donor and are fit for the operation needed to remove a kidney.

Ideally, living donations will come from a close relative because they are more likely to share the same tissue type and blood group as the recipient, which reduces the risk of the body rejecting the kidney. However donations from those who are not blood relatives are sometimes possible.

Kidney donations are also possible from people who have recently died. This is known as deceased kidney donation. However, this type of kidney donation has a slightly lower chance of long-term success.

Waiting for a kidney

People who need a kidney transplant, but do not have a suitable living donor, will have to wait until a suitable deceased donor kidney becomes available. This will ideally be from a donor with the same tissue type and blood group as the recipient, to reduce the risk of the body rejecting the kidney.

On average, the waiting time for a deceased donor kidney transplant is about three years. Waiting times are so long because the demand for donated kidneys in the UK is far higher than the available supply of donors.

From April 2012 to April 2013, around 3,000 kidney transplants were carried out in the UK, but there were still more than 6,000 people on the waiting list for a kidney by the end of this period.

Kidney donors are particularly required from people of non-white ethnic origin because rates of kidney disease are especially high in people of South Asian, African and Caribbean ethnic origin, but there are not many donors from these communities.

The transplant procedure

If you receive a kidney from a living donor, this will be a carefully planned operation.

If you are waiting for a deceased donor kidney, the transplant centre will contact you if a suitable kidney becomes available. This can happen at any time of the day or night. Staff at the centre will check you don't have any new medical problems and will ask you to go to the centre, where final checks will be performed to be sure it is right for the transplant to go ahead.

You will then have surgery to insert the new kidney and connect it to your blood vessels and bladder. The new kidney will be placed in the lower part of your abdomen (tummy). Your own kidneys will usually be left in place.

A kidney transplant is a major surgical procedure with a wide range of potential risks. In the short term, these risks include blood clots and infection. Longer term problems, which include diabetes and an increased risk of infections, are usually related to the immunosuppressant medication that needs to be taken continuously to reduce the chance of rejection.

Because of the risk of further problems, people who have had a kidney transplant require regular check-ups for the rest of their life.

Living with a kidney transplant

Having a healthy lifestyle after a kidney transplant goes a long way to minimising the risk of complications.

Therefore, it’s recommended that you:

  • stop smoking if you smoke
  • eat a healthy diet
  • lose weight if you are overweight or obese
  • take steps to reduce your risk of developing infections

How long do kidney transplants last?

There are a number of factors which affect how long a transplanted kidney may last. These include whether or not the kidney came from a living donor, how well the kidney is matched in terms of blood group and tissue type, the age of the person receiving the donation, and the overall health of the person receiving the donation.

Overall, average kidney survival times are:

  • 1 year – 85-95%
  • 5 years – 70-80%
  • 15 years – 50-60%

If you have a kidney transplant that fails, you are usually suitable for another transplant from either a living or deceased donor.
