Kidney Transplant: Who Needs It, How It Works and What to Expect

What Is a Kidney Transplant?

A kidney transplant is an operation in which a healthy kidney from a donor is placed into the body of a person whose kidneys can no longer work adequately.

The transplanted kidney takes over essential functions such as filtering waste products and excess fluid from the blood.

Kidney transplantation is one of the main treatment options for kidney failure. It is not considered a cure, because patients require lifelong medical follow-up and usually need anti-rejection medication for as long as the transplanted kidney continues to function.

Who May Need a Kidney Transplant?

A kidney transplant may be considered for patients with advanced chronic kidney disease or kidney failure.

Possible causes include:

• Diabetes-related kidney disease
• Long-term high blood pressure
• Polycystic kidney disease
• Glomerular diseases
• Congenital kidney disorders
• Certain autoimmune diseases
• Other conditions that permanently damage kidney function

Some patients receive dialysis while waiting for a transplant, while selected patients may undergo transplantation before dialysis becomes necessary.

Not every person with kidney failure is suitable for transplantation. The transplant team must determine whether surgery and long-term immunosuppressive treatment can be performed safely.

How Is a Patient Evaluated?

Before transplantation, the patient undergoes a detailed medical assessment at a transplant center.

This may include:

• Blood and urine tests
• Heart and lung evaluation
• Imaging examinations
• Infection screening
• Cancer screening when appropriate
• Blood group and tissue matching
• Assessment of other medical conditions

The transplant team also evaluates whether the patient understands the long-term medication and follow-up required after surgery.

Living Donor and Deceased Donor Kidney Transplant

A donated kidney may come from a living donor or a deceased donor.

Living Donor

A healthy person may donate one kidney because most people can live normally with a single healthy kidney.

The donor undergoes extensive testing to confirm that donation is medically safe and that the kidney is suitable for the recipient.

Living-donor transplantation can often be planned in advance, which may reduce or eliminate time spent waiting for a deceased-donor organ.

Deceased Donor

A kidney may also come from a deceased donor whose organs are suitable for transplantation.

Patients approved for this type of transplant are generally placed on a waiting list according to the transplant system in their country. Waiting times can vary considerably because the number of patients needing kidneys is greater than the number of available organs.

What Happens During the Operation?

During kidney transplant surgery, the donor kidney is usually placed in the lower part of the abdomen.

The surgeon connects the kidney to the patient's blood vessels and connects the donor ureter to the bladder so that urine can flow normally.

In most cases, the patient's own kidneys are left in place unless they are causing a specific problem such as repeated infection, uncontrolled high blood pressure or another medical complication.

Some transplanted kidneys begin working immediately, while others may take several days to start functioning fully.

Recovery After Kidney Transplant

Patients usually remain in hospital for several days after surgery, although recovery time varies.

During this period, the transplant team closely monitors:

• Kidney function
• Urine production
• Blood pressure
• Blood test results
• Signs of infection
• Signs of rejection

After discharge, patients attend frequent follow-up visits and blood tests. These appointments become less frequent as kidney function becomes stable.

Rejection and Anti-Rejection Medication

The immune system naturally tries to attack tissues that it recognizes as foreign.

To protect the transplanted kidney, patients must take immunosuppressive medicines, also called anti-rejection medicines.

These medicines are extremely important and should never be stopped or changed without advice from the transplant team.

Because immunosuppressive medication reduces immune activity, it can increase the risk of infections and may cause other side effects.

Regular blood tests help doctors monitor kidney function and detect early signs of rejection, sometimes before the patient develops noticeable symptoms.

What Are the Possible Risks?

Kidney transplantation is major surgery and can involve risks such as:

• Bleeding
• Infection
• Blood clots
• Urinary complications
• Rejection of the transplanted kidney
• Delayed function of the new kidney
• Side effects from immunosuppressive medication

The risks differ from patient to patient, which is why careful evaluation before transplantation is essential.

Life After Kidney Transplant

A successful transplant can allow many patients to live without regular dialysis and return gradually to work, exercise and everyday activities.

However, maintaining the transplanted kidney requires long-term commitment.

Patients must take their medicines correctly, attend follow-up appointments, maintain a healthy lifestyle and contact their transplant team if they develop concerning symptoms.

Kidney transplantation is not simply an operation. It is a long-term treatment process involving nephrologists, transplant surgeons, nurses and other specialists working together to protect both the patient and the transplanted kidney.
