ABSTRACT

Objective: To report a case of fibroepithelial polyp of the ureter. The presence of polyps in the urinary tract is rare. They are benign lesions with no malignant potential. They consist of a cone of fibrovascular stroma emerging from the mucosa and covered by normal transitional epithelium.
Clinical case: The patient is a 59-year-old female with a long progression of dysuria and occasional suprapubic pain. At times she presented with intermittent urination. Ultrasound of the bladder produced hyperechoic image with no acoustic shadowing. Excretory urography showed no signs of pyelocaliceal ectasia but revealed a bladder filling defect. Cystoscopy showed growth on right ureteral meatus protruding toward the bladder. The mass was completely resected using endoscopic laser and ureteral fibroepithelial polyp was reported.
Discussion: The majority of fibroepithelial polyps occur in the ureter. They appear to be slow growing congenital lesions or anomalies that develop due to chronic exposure to urothelial irritants such as infection, inflammation or obstruction. Diagnosis is complicated. Treatment should be individualized. Nephrouretectomy is one of many treatment options. However, currently endoscopic treatments are recommended when the lesion is small and its base has been identified.
