A kidney transplant is a surgical procedure that replaces a diseased kidney with a healthy one from a donor, offering effective treatment for end-stage kidney disease and improved patient quality of life. The process involves pre-transplant evaluation, finding a suitable donor, a surgical procedure, and post-transplant care, including lifelong immunosuppressive medication to prevent organ rejection. While there are risks associated with the transplant, the benefits include enhanced longevity, fewer dietary restrictions, and freedom from dialysis.
