Fibroepithelial polyps of ureter. A benign ureteral tumor.

The authors believe that it is difficult to differentiate benign from malignant ureteral tumors unless the clinical course or cytologic diagnostics are grossly positive. Therefore, they are of the opinion that unless one's index of suspicion is low, treatment of ureteral tumors should be aggressive unless benignancy is assured. A case in point is reported, and 49 cases of nonepithelial polyps found in the literature are reviewed.
