Definition: Kidney transplantation

Kidney transplantation is the surgical transfer of a healthy kidney into a patient with end-stage renal disease.

CISCE: Class 12

Introduction and Historical Milestones

The surgical transplantation of a kidney into a patient suffering from end-stage renal disease.

  • First Documented Transplant: Performed in the USA on June 17, 1950, on Ruth Tucker. The organ was eventually rejected due to the lack of immunosuppressive therapy at the time.
  • First Successful Transplant: Performed in 1954 at Brigham Hospital in Boston by Joseph E. Murray and J. Hartwell Harrison. It was done between identical twins to completely prevent an immune reaction. Murray received the Nobel Prize in Medicine in 1990 for this achievement.

Donor Selection and Pre-Transplant Evaluation

Kidneys from living donors generally function better and last longer than those from cadaveric (deceased) donors.

  • Donor Requirements: Potential donors must have a compatible blood type, no transmissible diseases, two healthy kidneys, and the physical ability to live well with only one kidney.
  • Evaluation Tests: Both donor and recipient undergo tests, including blood tests for compatibility, as well as urine studies, chest X-rays, EKGs, abdominal ultrasounds, and echocardiograms to check the health of vital organs.

Surgical Procedure

  • The surgery is performed under general anaesthesia and takes about three to five hours.
  • The patient's original, diseased kidneys are typically left in place.
  • The new kidney is positioned lower down in the abdomen.
  • Its blood vessels are connected to the blood vessels that supply the leg, and its ureter is attached directly to the bladder.

Post-Operative Function and Rejection

  • Functionality: Most new kidneys begin working immediately. However, up to 30% take longer to function properly, requiring the patient to undergo temporary haemodialysis until the kidney starts working.
  • Signs of Rejection: Symptoms include decreased urine output, sudden weight gain, high blood pressure, elevated creatinine levels, fever, racing pulse, weakness, and swelling in the extremities or around the transplant site.
  • Treatment for Rejection: Rejection is managed with medications, specifically immunosuppressant drugs, which suppress the immune system to prevent it from attacking the donor kidney.

Post-Transplant Care

  • Exercise: Regular physical activity is highly recommended, as it reduces stress, enhances well-being, and significantly improves the patient's quality of life.
  • Diet: Kidney recipients must follow a specific diet that is low in fat and high in magnesium and phosphorus.

Key Points: Kidney Transplantation

  • Kidney transplantation is a surgical treatment specifically for patients suffering from end-stage renal disease.
  • The first successful kidney transplant was performed in 1954 between genetically identical twins.
  • Kidneys obtained from living donors typically function better and last longer than those from deceased donors.
  • During the operation, the new kidney is placed in the lower abdomen while the patient's original kidneys are usually left in place.
  • Immunosuppressant medications are required to prevent the patient's immune system from rejecting the new donor kidney.
  • Following surgery, patients must follow a specific diet low in fat and high in magnesium and phosphorus.
