Kidney transplantation is a medical procedure that involves replacing a diseased or damaged kidney with a healthy one from a donor. The donor can be living or deceased, and the new kidney takes over the function of filtering waste and excess fluids from the blood. This procedure is often necessary for individuals with end-stage renal disease or severe kidney dysfunction. After the surgery, patients must take medications to prevent their body from rejecting the new kidney. Regular follow-up appointments are essential to monitor kidney function and overall health. Successful transplantation can significantly improve the quality of life for those with kidney failure.
