Inverted papilloma of the ureter

: We report a case of inverted urothelial papilloma localized to the ureter in a patient with solitary kidney. Treatment was by segmental resection and end-to-end anastomosis. In spite of the benign nature of this tumor type and because treatment is conservative, patients should be closely followed owing to the possibility of recurrence and because progression to malignancy has been reported in the literature.
