Snake-shaped tumor protruding from an ureteral orifice: a case of a long ureteral fibroepithelial polyp successfully resected ureteroscopically.

ABSTRACT: A fibroepithelial polyp (FEP) is a rare benign ureteral tumor that causes gross hematuria and ureteral obstruction. Diagnosis of FEP is difficult using ultrasound or radiographic imaging, and ureteroscopic diagnosis through direct vision is important. Although ureteroscopic resection is less invasive, FEP sometimes grows significantly in both length and size and requires open or laparoscopic ureteral resection. Here, we report a case in which we diagnosed and resected a 9.5 cm long FEP, originating from the mid-ureter, ureteroscopically. A 32-year-old woman with gross hematuria was referred to our hospital. Cystoscopy revealed a snakelike tumor protruding from the left ureteral orifice into the bladder. Ureteroscopy revealed a smooth tumor surface, with the root sufficiently narrow for res
