[Fibro-epithelial polyps of the urinary tract. Apropos of 2 new cases (of the ureter and bladder)].

Fibroepithelial polyps are benign mesodermal tumors that may be localized at any level of the urinary tract. However, the ureter and urethra are uncommon sites and these are rarely found in the bladder. Two cases are described involving the middle ureteral third and the bladder. We discuss the different hypotheses regarding its etiology and describe the clinical features, diagnostic methods and treatment. We underscore its benign natural history, treatment by conservative surgery and non-recurrence.
