Fibrous polyp of the ureter.

The most frequent ureteral tumors are transitional carcinoma. Benign neoplasms are uncommon. In this paper we present 6 cases of ureteral polyps, which represent 11.1% of all the tumors in our series of ureteral tumors. We have reviewed the possible etiopathogenesis and exposed the clinical characteristics. Secondary to the obstructive phenomenon and the radiologic signs, it is the tigroid appearance, the localization and the absence of total obstruction which allows the diagnostic suspicion. The treatment of choice is partial resection. Ureterostomy with peroperatory biopsy, in cases in which the malignancy is not yet established, is recommended in order to avoid unnecessary nephroureterectomies.
