Kidney transplantation provides better long-term survival and quality of life than dialysis for patients with end-stage renal disease. While the first successful kidney transplants were between twins in 1954, transplantation techniques and anti-rejection drugs have improved outcomes over decades. Living donors are preferred as they offer reduced rejection rates and improved graft survival, though deceased donors also help many patients. Preemptive transplantation before dialysis starts provides the best results, but early transplantation once on dialysis also benefits patients.
