A 42-year-old woman underwent 131I radiotherapy for thyroid papillary cancer. A focal elevated 131I activity in the right kidney was revealed on the initial whole-body posttherapeutic images, which was located in the region of a renal stone. However, on the follow-up 131I images acquired 6 months later, there was no longer any increased activity in the region of this stone, which had moved into right ureter. Our case indicates that the 131I activity accumulated in the region of urinary stone is due to stagnated radioactive urine rather than due to the stone per se.
