case_images: The lesion was resected by performing monopolar cautery with a Bugbee electrode, and the specimen was extracted through the ureteral orifice and was exteriorized outside the urethra by using forceps (Fig. 4).
case_images: Histologic preparation of fibroepithelial polyp showing stroma covered by layer of normal transitional epithelial cells (Hematoxylin&Eosin 40 x ).
