The diseased kidney can also be replaced by a healthy donor kidney
The Kidney could be rejected by the immune system
Antigens on the surface of cells tell your WBC's your cells are self cells
antibodies are released to attack & destroy foreign & unrecognised cells
Blood & tissue type checks must be carried out before a donation
Problems
Transplant patients have to take immunosuppressant drugs for the rest of their lives
