[Two cases of benign polypes of the ureter (author's transl)].

The polyp of the ureter is a tumour which originates in the connective tissue and is covered by normal urothelium. Radical surgery is justified in some of these urothelial tumours but one should also consider a more conservative attitude when one deals with a benign fibro-epithelial polyp of the ureter especially when they are located in the lower or upper third of the ureter. We present two cases, one which represents the eleventh case of benign fibro-epithelial polyp described in children in the literature.
