TRANSPLANTATIONS

If you have advanced and permanent kidney failure, kidney transplantation may be the treatment option that allows you to live much like you lived before your kidneys failed. Since the 1950s, when the first kidney transplants were performed, we've learned much about how to prevent rejection and minimize the side effects of medicines.

But transplantation is not a cure; it's an ongoing treatment that requires you to take medicines for the rest of your life and the wait for a donated kidney can be years long.

A successful transplant takes a coordinated effort from your whole health care team, including your nephrologist, transplant surgeon, transplant coordinator, pharmacist, dietitian, and social worker. The most important members of your health care team are you and your family. By learning about your treatment, you can work with your health care team to give yourself the best possible results, and you can lead a full, active life.

Getting Ready
The transplantation process has many steps. First, talk with your doctor, because transplantation isn't for everyone. Your doctor may tell you that you have a condition that would make transplantation dangerous or unlikely to succeed.

You may receive a kidney from a member of your family (living, related donor), from a person who has recently died (cadaveric donor), or sometimes from a spouse or a very close friend (living, unrelated donor). If you don't have a living donor, you're placed on a waiting list for a cadaveric kidney. The wait for a cadaveric donor kidney can be several years.

The transplant team considers three factors in matching kidneys with potential recipients. These factors help predict whether your body's immune system will accept the new kidney or reject it.

  • Blood type. Your blood type (A, B, AB, or O) must match the donor's. This is the most important matching factor.

  • Human leukocyte antigens (HLAs). Your cells carry six important HLAs, three inherited from each parent. Family members are most likely to have a complete match. You may still receive a kidney if the HLAs aren't a complete match as long as your blood type matches the organ donor's and other tests are negative.

  • Cross-matching antigens. The last test before implanting an organ is the cross-match. A small sample of your blood will be mixed with a sample of the organ donor's blood in a tube to see if there's a reaction. If no reaction occurs, the result is called a negative cross-match, and the transplant operation can proceed.

Possible Complications
Transplantation is the closest thing to a cure. But no matter how good the match, your body may reject your new kidney. A common cause of rejection is not taking medication as prescribed.

Your doctor will give you drugs called immunosuppressants to help prevent your body's immune system from attacking the kidney, a process called rejection. You'll need to take immunosuppressants every day for as long as the transplanted kidney is functioning. Sometimes, however, even these drugs can't stop your body from rejecting the new kidney. If this happens, you'll go back to some form of dialysis and possibly wait for another transplant.

Immunosuppressants can weaken your immune system, which can lead to infections. Some drugs may also change your appearance. Your face may get fuller; you may gain weight or develop acne or facial hair. Not all patients have these problems, though, and diet and makeup can help.

Immunosuppressants work by diminishing the ability of immune cells to function. In some patients, over long periods of time, this diminished immunity can increase the risk of developing cancer. Some immunosuppressants can cause cataracts, diabetes, extra stomach acid, high blood pressure, and bone disease. When used over time, these drugs may also cause liver or kidney damage in a few patients.

 

How It Works
Kidney transplantation is a procedure that places a healthy kidney from another person into your body. This one new kidney takes over the work of your two failed kidneys.

A surgeon places the new kidney inside your lower abdomen and connects the artery and vein of the new kidney to your artery and vein. Your blood flows through the new kidney, which makes urine, just like your own kidneys did when they were healthy. Unless they are causing infection or high blood pressure, your own kidneys are left in place.

The Time It Takes
How long you'll have to wait for a kidney varies. Because there aren't enough cadaveric donors for every person who needs a transplant, you must be placed on a waiting list. However, if a voluntary donor gives you a kidney, the transplant can be scheduled as soon as you're both ready. Avoiding the long wait is a major advantage of living donation.

The surgery takes 3 to 4 hours. The usual hospital stay is about a week. After you leave the hospital, you'll have regular followup visits.

If someone has given you a kidney, the donor will probably stay in the hospital about the same amount of time. However, a new technique for removing a kidney for donation uses a smaller incision and may make it possible for the donor to leave the hospital in 2 to 3 days.

Between 85 and 90 percent of transplants from cadaveric donors are working 1 year after surgery. Transplants from living relatives often work better than transplants from cadaveric donors because they're usually a closer match.

Diet for Transplantation
Diet for transplant patients is less limited than it is for dialysis patients, although you may still have to cut back on some foods. Your diet will probably change as your medicines, blood values, weight, and blood pressure change.

  • You may need to count calories. Your medicine may give you a bigger appetite and cause you to gain weight.

  • You may have to eat less salt. Your medications may cause your body to retain sodium, leading to high blood pressure.

 

 

Pros
  •  A transplanted kidney works like a normal kidney.

  • You may feel healthier or "more normal."

  • You have fewer diet restrictions.

  • You won't need dialysis.

  • Patients who successfully go through the selection process have a higher chance of living a longer life.

Cons
  • It requires major surgery. You may need to wait for a donor.

  • Your body may reject the new kidney, so one transplant may not last a lifetime.

  • You'll need to take immunosuppressant, which may cause complications.
