Bilateral organ-limited amyloidosis of the distal ureter associated with osseous metaplasia and radiographic calcification.

We report a case of organ-limited amyloidosis of the distal portion of both ureters in which bilateral osseous metaplasia was present as well as radiographic evidence of ureteral wall calcification. This case represents the twenty-eighth report of localized ureteral amyloidosis and the fourth report with bilateral involvement.
