Kidney transplantation or renal transplantation is the organ transplant of a kidney into a patient with the end-stage renal disease. Kidney transplantation is typically classified as deceased-donor (formerly known as cadaveric) or living-donor transplantation depending on the source of the donor organ. Living-donor renal transplants are further characterized as genetically related (living-related) or non-related (living-unrelated) transplants, depending on whether a biological relationship exists between the donor and recipient.
In most cases, the diseased kidneys are left in place during the transplant procedure. The transplanted kidney is implanted in the lower abdomen.
