Inverted papilloma of the ureter

The clinical and pathological findings of a case of inverted papilloma of the ureter are reported. Treatment consisted of partial ureteral resection, followed by end-to-end anastomosis. This uncommon lesion can be considered as a benign neoplasm, since recurrence and malignant degeneration are quite exceptional. Therefore a plea is made for conservative surgical treatment, although careful long term follow-up is advisable.
