The transplanted organ comes from two types of donors: deceased donors and living donors.
Deceased donors: Most of the transplanted kidneys come from deceased donors. The organ donors are adults or children who may have agreed to be an organ donor before becoming ill. The family of the deceased person must agree to donate the organs as well.
Living donors: The donor kidney can also come from family members or people who are a good match. They can safely donate one kidney and live a healthy life with the other one. It is possible for a child older than two years to receive an adult kidney.
