A man with end-stage kidney disease survives for a record 271 days after receiving a genetically modified pig kidney, staying off dialysis before ultimately receiving a human kidney. Multiple outlets describe the case as a milestone for xenotransplantation and report that the pig kidney later began failing, prompting the next transplant step.
The patient, identified in several reports as Tim Andrews, receives the pig kidney as a temporary “bridge” while he waits for a suitable human donor organ. Outlets note his condition was linked to type 2 diabetes and that he faced a low likelihood of receiving a human kidney within a multi-year period. Coverage also emphasizes that surgeons in the US performed the xenotransplant using a kidney engineered to be compatible with the recipient’s immune system.
Differences across sources are mainly in emphasis. Some outlets focus on the record length of time without dialysis, others highlight the bridging strategy that kept him alive until a later human transplant. Several also frame the result as evidence of potential but do not claim it resolves the wider organ shortage, with further progress dependent on safety and long-term outcomes. Researchers discuss the findings in a peer-reviewed paper published in *The Lancet*.
