Fibroepithelial Polyp of the Ureter
Fibroepithelial Polyp of the Ureter
A 73-year-old woman presented with asymptomatic gross hematuria. Her physical examination was unremarkable. A complete blood cell count, levels of serum electrolytes and creatinine, and results of cytologic evaluation of voided urine were normal. Urinalysis showed 0 to 2 white blood cells and 25 to 50 red blood cells per high-power field. Urine culture was negative.
An excretory urogram and left retrograde ureteropyelogram demonstrated a filling defect within the distal left ureter (Figures 1A and 1B). Cystourethroscopy revealed tissue visible within the left ureteral orifice (Figure 2). A biopsy was performed that demonstrated a fibroepithelial polyp (Figures 3A and 3B).

Excretory urogram shows a filling defect in the distal left ureter (large white arrow). A malrotated ptotic right kidney (small straight arrows), clips from cholecystectomy (arrowheads), and pancreatic calcifications (curved arrows) are also shown.

Left retrograde ureteropyelogram demonstrates filling defects throughout the distal left ureter.

A branching polyp is observed in the distal left ureter adjacent to a guidewire.

One of the lobulated projections of the fibroepithelial polyp shows benign urothelium covering a broad-based edematous fibrovascular stroma (hematoxylin-eosin, ×10).
(Enlarge Image)
The fibroepithelial polyp is characterized by normal or hyperplastic urothelium overlying an intact basement membrane with extensive submucosal edema, dilated blood vessels, chronic inflammatory cells, and fibrous stroma (hematoxylin-eosin, ×40).
