A rare case of successful endoscopic management of a fibroepithelial polyp with intussusception of the ureter and periodic prolapse into bladder

摘要

Fibroepithelial polyps of the ureter are rare non-epithelial benign tumours with a slight female predominance. They are primarily located in the upper left ureter, incidentally diagnosed in patients who are evaluated for gross haematuria or renal colic. Fibroepithelial polyps are traditionally managed by open surgery with resection of the polyp and its stalk or partial resection of the ureter. We describe the case of a fibroepithelial polyp located in the distal right ureter, which occurred in a 42-year-old man with lower urinary tract symptoms, haematuria and flank pain. To our knowledge, this is the first reported case of ureteral fibroepithelial polyp acting as a lead point for ureteral intussusception and to protruding periodically into the bladder cavity, which was successfully resected by ureteroscopic electrocauterisation with good outcome.
