A 66-year-old man with terminal kidney failure caused by type 2 diabetes received a genetically modified pig kidney as a temporary bridge to a human organ. ^[1] Mass General Brigham reported that a 66-year-old man with end-stage renal failure caused by type 2 diabetes survived nine months without dialysis using a genetically modified pig kidney. ^[2] The genetically modified pig kidney was transplanted in January 2025 and functioned immediately. ^[3] The patient had an estimated 9% chance of receiving a human kidney within five years and a risk of death or removal from the waiting list exceeding 40%. ^[4] The procedure was performed at Mass General Brigham in the United States and published in The Lancet. ^[5] The patient had a 9% estimated probability of receiving a human kidney within five years and faced a risk of over 40% of dying or being removed from the waiting list. ^[6] The patient survived 271 days without dialysis, representing the longest recorded survival time without dialysis after a porcine xenotransplant. ^[7] The pig kidney was sourced from a miniature Yucatan pig and genetically modified to be compatible with the human immune system. ^[8]
