Benign fibroepithelial ureteral polyps. Report of 3 cases

Three rare cases of benign ureteral polyps are presented. The rareness of benign mesenchymal ureteral tumors and the difficulty in pre-operative differential diagnosis from malignant epithelial are remarkable. The diagnosis is made on characteristic appearance at operation and is confirmed by frozen section and histological examination. Minerva Urol Nefrol
