This week, surgeons in the Washington, D.C. area performed an unprecedented 26-person mix-and-match kidney transplant. The massive transplant was done through a "paired kidney donation" program, where one incompatible donor/recipient pair are matched with another; the donor of the first kidney gives to the recipient of the second and vice versa. Experts say paired donations such as this will eventually allow for an extra 3,000 living donor transplants a year in the U.S. Visit Healthline Connects to read more.
