[Fibroepithelial polyps of the ureter].

The fibroepithelial polyps is a rare benign tumor, that can rise at any level of the upper urinary tracts with a major predisposition at the pyeloureteral junction. The exact etiology is not known, even if we remember that chronic irritation, stasis and infection sometimes caused by an associated calculus are important factors in the genesis of the tumor. The authors report 3 new cases with ureteral seat, of which one is associated with a calculus. This fact underlines the importance of an exact differential diagnostic with the carcinoma as well for the conservative treatment as for the prognosis which is favourable.
