Kidney transplant or renal transplant is that the transplant of a kidney into a patient with end-stage renal disorder (ESRD). Kidney transplant is usually classified as deceased-donor (formerly referred to as cadaveric) or living-donor transplantation counting on the source of the donor organ. Living-donor kidney transplants are further characterized as genetically related (living-related) or non-related (living-unrelated) transplants, counting on whether a biological relationship exists between the donor and recipient.
