    "prose": "Andrews successfully lived with the genetically edited pig kidney for 271 days without needing dialysis before receiving a human kidney from a donor. [^1]\n\nTim Andrews, a 66-year-old patient with end-stage kidney disease, received a genetically edited pig kidney in January 2025 and subsequently received a human kidney in January 2026. [^2]\n\nTim Andrews, a patient at Mass General Brigham hospital in the US, received a kidney transplant from a pig that functioned for 271 days, which the medical team states is the longest duration on record. [^3]\n\nLead author Leonardo Riella, M.D., Ph.D., of Mass General Brigham stated that xenotransplantation could help address the organ shortage gap by initially serving as a bridge to get patients off dialysis while they wait for a human donor kidney. [^4]\n\nThis case represents the longest dialysis-free survival following porcine kidney xenotransplantation in a living human and the first transition to human kidney transplantation. [^5]\n\nIn the US, approximately 100,000 people are waiting for a kidney transplant while only 25,000 transplants occur each year. [^6]\n\nThe medical team at Mass General Brigham says their work demonstrates that pig organs can serve as a bridge until a human transplant becomes available. [^7]\n\nThe patient had required dialysis for two years prior to the intervention due to failed kidneys. [^8]",
