title: Dystrophic ureteral calcification associated with Churg-Strauss vasculitis.
abstract: Churg-Strauss syndrome is an uncommon systemic vasculitis affecting small blood vessels. Renal involvement is typical; however, calcinosis of the urinary tract has not previously been described. Dystrophic calcification in the urinary tract is rare, although it is occasionally associated with schistosomiasis, tuberculosis, and polyarteritis nodosa. We report the case of a 19-year-old man with newly diagnosed Churg-Strauss syndrome who presented to us with dystrophic calcification in both ureters causing bilateral obstruction.
