LOS ANGELES (AP) — A University of Southern California-affiliated hospital has reactivated its kidney transplant program after a doctor put the wrong kidney into a patient who survived the error.

USC University Hospital’s transplant director Dr. Cynthia Herrington said Tuesday the program was restarted Monday after voluntarily shutting down Feb. 4 to strengthen patient safety standards.

The mix-up occurred Jan. 29 after two kidneys from separate donors arrived at the transplant center.
