A kidney transplant is a surgical procedure to replace a diseased kidney with a healthy kidney from a donor. It's often necessary for patients with end-stage renal disease or severe kidney failure. The donor kidney can come from a living donor or a deceased donor. Before the transplant, patients undergo thorough evaluations to ensure compatibility and readiness for surgery. Post-transplant, recipients must take immunosuppressive medications to prevent organ rejection. The goal is to restore normal kidney function, improve quality of life, and increase lifespan. Kidney transplants have high success rates and can significantly reduce or eliminate the need for dialysis.
