Abstract: OBJECTIVE: Fibroepithelial polyps of ureter prolapsing into the
bladder are a rare urological condition. We report the imaging findings and our
experience with endoscopic treatment for ureteral fibroepithelial polyps
prolapsing into the bladder. PATIENTS AND RESULTS: Four patients with frank pain and hematuria
were enrolled. Intravenous urography and computed tomography revealed a
ureteral mass with filling defects in affected ureter and mild hydronephrosis.
Endoscopic examination showed ureteral polyps prolapsing in the bladder. The
histopathologic diagnosis on 4 cases was benign fibroepithelial polyps of
ureter. The largest polyps (from 4–10 cm in length) were successfully
resected and vaporized by Holmium: YAG laser. A double-pigtail ureteral stent
at 7F was placed and left for 6 weeks after the procedure. Neither recurrence
nor ureter stricture was observed after up to 12 years of follow-up. CONCLUSIONS: Ureteral malignancy must be excluded in cases where a
ureteral mass is detected. Endoscopic management is recommended to minimize
morbidity and complications in treatment of ureteral fibroepithelial polyps
that prolapse into the bladder.
