### Groundbreaking Medical Milestone: New Hampshire Man's Journey with a Pig Kidney Tim Andrews, a 67-year-old man from Concord, New Hampshire, has made headlines by living with a genetically modified pig kidney for a record-setting **271 days**. This unprecedented medical event took place at Massachusetts General Hospital, where the transplant was performed in January 2025. The kidney was removed on October 23, 2025, due to a decline in its function, marking a significant moment in the field of xenotransplantation, which aims to address the shortage of human organ donors [https://www.straitstimes.com/world/united-states/pig-kidney-removed-from-us-transplant-patient-after-nine-months][https://www.thedailyjagran.com/us/news/pig-kidney-removed-from-man-who-survived-271-days-without-dialysis-10276356]. ### Structure of the Medical Journey and Its Implications 1. **Transplant Background** - Tim Andrews received the pig kidney as part of an experimental procedure aimed at exploring the viability of animal organs for human transplantation. This was part of a broader research initiative to alleviate organ shortages [https://apnews.com/article/pig-kidney-xenotransplant-dialysis-7bb8dcc1a2e02bc16a9a27ef8071ee64]. 2. **Duration and Performance** - The kidney functioned for **271 days**, a record duration for such a transplant. However, its performance began to decline, prompting medical professionals to remove it [https://www.independent.co.uk/life-style/health-and-families/health-news/pig-kidney-tim-andrews-transplant-organ-removed-b2853257.html]. 3. **Post-Transplant Care** - Following the removal of the pig kidney, Andrews has returned to dialysis, a treatment he had been undergoing prior to the transplant.
