Imaging diagnosis and endoscopic treatment for ureteral fibroepithelial polyp prolapsing into the bladder

J Xray Sci Technol. 2013;21(3):393-9. doi: 10.3233/XST-130390.


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.
