[Fibroepithelial polyps of the ureter: report of three new cases].

The fibroepithelial polyp of the ureter is a benign tumour with a mesenchymal origin. Since its incidence is low, there are very few cases published in the national literature. Presentation of our series, which consists of three cases seen and treated in our service over the last 10 years. Discussion of the most frequent characteristics seen in this type of disease and emphasis on its great relevance for the differential diagnosis with other causes of ureteral repletion deficiency.
