A single kidney that was transplanted twice in two weeks is working fine after what appears to be the first-ever case of doctors salvaging a hand-me-down organ after it started to fail.

Erwin Gomez, a 67-year-old Chicago-area surgeon and father of five, is the third and, hopefully, final owner of the kidney, which was transplanted last June 16 — and again on June 30 — at Northwestern Memorial Hospital in Chicago.
