[Inverted papilloma of the ureter. Unusual presentation and review of the literature].

A case of inverted papilloma localized in the left pelvic ureter is described. The patient was submitted to a URS procedure with excisional biopsy of the tumor and fulguration of its base using the electric ureteral resectoscope. We believe that currently available endourologic techniques are the procedure of choice in the diagnosis of upper GU tract filling defects. An endourologic procedure permits conservative treatment when indicated and direct vision of the tumor site and urothelial mucosa.
