Kidney Transplantation
What is Kidney Transplantation?
Kidney transplantation is a surgical procedure that places a healthy kidney from a donor into a person whose kidneys no longer function properly. This treatment option offers people with end-stage kidney disease a chance to live without dialysis. The new kidney can come from a living donor, often a family member or friend, or from someone who has recently died.
The transplant process requires careful matching between donor and recipient to prevent rejection. Your immune system naturally attacks foreign tissue, so doctors must find a donor whose blood type and tissue markers are compatible with yours. Blood type compatibility is the first and most critical step in determining if a transplant can proceed safely.
After transplant, most recipients take anti-rejection medications for life to help their body accept the new organ. When successful, a transplanted kidney can function for many years and dramatically improve quality of life. Many people return to work, travel, and enjoy activities that dialysis made difficult.
Symptoms
- Severe fatigue and weakness from kidney failure
- Swelling in legs, ankles, and feet from fluid buildup
- Shortness of breath when fluid accumulates in lungs
- Nausea, vomiting, and loss of appetite
- Difficulty concentrating and mental fog
- Muscle cramps and twitching
- Persistent itching across the skin
- Changes in urination patterns or volume
- High blood pressure that is hard to control
- Metallic taste in mouth and bad breath
These symptoms indicate advanced kidney disease that may require transplantation. Some people experience gradual symptom onset over months or years before reaching transplant consideration.

Causes and risk factors
Kidney transplantation becomes necessary when chronic kidney disease progresses to end-stage renal failure. The most common causes include diabetes, which damages small blood vessels in the kidneys over time, and high blood pressure, which strains kidney filtering units. Other causes include polycystic kidney disease, an inherited condition where cysts grow in the kidneys, glomerulonephritis, which inflames the kidney filters, and repeated kidney infections.
Risk factors for needing a transplant include poorly controlled diabetes, unmanaged high blood pressure, family history of kidney disease, prolonged use of certain pain medications, and autoimmune diseases like lupus. African Americans, Hispanics, and Native Americans face higher rates of kidney disease. Smoking, obesity, and heart disease also increase risk of kidney failure requiring transplantation.
How it's diagnosed
Transplant candidacy begins with blood type testing to determine ABO and Rh factor compatibility with potential donors. This initial screening is essential because incompatible blood types can cause immediate and severe rejection of the transplanted kidney. Doctors also perform tissue typing tests to match human leukocyte antigens, or HLA markers, between donor and recipient. Additional tests assess overall health, screen for infections, and check heart and lung function to ensure you can safely undergo major surgery.
Rite Aid offers ABO Blood Type and Rh Factor testing as an add-on to help you understand your transplant compatibility. This foundational test is the first step in the matching process. Your transplant team will also order kidney function tests, imaging studies, and crossmatch testing before surgery to minimize rejection risk.
Treatment options
- Immunosuppressant medications to prevent organ rejection taken daily for life
- Regular monitoring of kidney function through blood tests and checkups
- Heart-healthy diet low in sodium to protect the new kidney
- Staying active with regular exercise approved by your transplant team
- Avoiding tobacco and limiting alcohol consumption
- Maintaining healthy weight to reduce stress on the transplanted organ
- Drinking adequate water to support kidney function
- Careful medication management to avoid drugs that damage kidneys
- Infection prevention through hand washing and avoiding sick contacts
- Regular dental care to prevent infections that could affect the kidney

Frequently asked questions
ABO blood type compatibility between donor and recipient is mandatory for most kidney transplants. Type O recipients can only receive from type O donors, while type AB recipients can receive from any blood type. Type A can receive from A or O, and type B can receive from B or O. Special desensitization protocols exist for ABO-incompatible transplants but require additional treatment.
Living donor kidneys last an average of 15 to 20 years, while deceased donor kidneys typically function for 10 to 15 years. Individual results vary based on factors like age at transplant, medication adherence, overall health, and how well the donor kidney matched your tissue type. Some transplanted kidneys function for 30 years or more with proper care.
Most kidney transplant recipients return to work within 2 to 3 months after surgery. The timeline depends on the type of work you do and how quickly you recover. Physical jobs may require longer recovery time. Many people report better energy and ability to work compared to life on dialysis.
Organ rejection and infection are the two main risks following transplant. Immunosuppressant drugs prevent rejection but lower your body's ability to fight infections. Regular monitoring helps catch rejection early when it is most treatable. Other risks include high blood pressure, diabetes, cancer, and side effects from anti-rejection medications.
Yes, nearly all kidney transplant recipients take immunosuppressant medications for life to prevent rejection. Your immune system always recognizes the transplanted kidney as foreign tissue. Stopping these medications typically leads to organ rejection within weeks or months. Your transplant team adjusts doses over time based on your kidney function and side effects.
Family members often make excellent living donors because they may share compatible blood and tissue types. Siblings have the highest chance of being a good match. Parents, children, and extended family can also donate if compatible. Even spouses and close friends can be living donors if testing shows good compatibility.
Kidney transplant offers more freedom and better quality of life compared to dialysis. Dialysis requires 3 to 4 sessions per week for several hours each. A functioning transplant works 24 hours a day like natural kidneys. Most transplant recipients feel better, have fewer dietary restrictions, and can travel more easily than people on dialysis.
Eating a balanced diet low in sodium and processed foods protects your new kidney. Regular physical activity, maintaining healthy weight, and avoiding tobacco are essential. Staying hydrated, taking medications exactly as prescribed, and attending all follow-up appointments help ensure long-term transplant success.
Yes, people can receive multiple kidney transplants if previous transplants fail. Second and third transplants are possible, though finding compatible donors becomes more challenging. Your body may develop antibodies against certain tissue types after the first transplant, making matching more difficult but not impossible.
Regular blood tests check creatinine and other markers of kidney function to detect problems early. You will have frequent testing in the first months after transplant, then less often as your kidney remains stable. Urine tests, blood pressure checks, and medication level monitoring are also part of routine post-transplant care.
