Magnetic resonance imaging for ureteral fibroepithelial polyp.

چکیده
Ureteric tumours are rare and most of them are malignant. Of benign tumours, ureteral fibroepithelial polyps are the most common but are still considered clinical rarities. In the past, most benign ureteric tumours were only diagnosed after surgical removal. With technological advance, magnetic resonance imaging has become an effective means of assessing ureteric lesions. Non-contrast enhanced magnetic resonance urography can produce an image comparable to an intravenous urogram without use of intravenous water-soluble contrast. A polyp can be diagnosed on imaging if there is an elongated filling defect inside the ureter. Nevertheless, a definitive diagnosis relies on ureteroscopic examination with biopsy. When a non-obstructive polyp is being managed conservatively, imaging is helpful for monitoring. Equally, the information obtained from imaging can be used to plan operative treatment.

Rare giant primary ureteral polyp: A case report and literature review
Primary ureteral fibroepithelial polyps (UFPs) are rare benign tumors of mesodermal origin. The majority UFPs are observed in the proximal part of the ureter and most commonly on the left side. The mean diameter of UFP is reported to be <5 cm. We herein present a rare case of a long primary ureteral polyp originating from the lower ureter in a 53-year-old woman. Following computed tomography, m...

Background: Fibroepithelial polyps (FEPs) are a rare cause of ureteropelvic junction (UPJ) obstruction. Radiologists and urologists are not always confident with this disease because of its rarity, complex diagnosis, and heterogeneity of the available treatment options. Case Presentation: We present the endourologic diagnosis and the robotic management of a ureteral polyp close to the left UPJ....

An excretory urogram revealed right hydronephrosis and a filling defect of the the right midureter. The filling defect was produced by a large fibroepithelial polyp that was diagnosed and removed by ureteroscopy without open surgery. Large fibroepitheli...

Fibroepithelial polyps (FEPs) are rare benign ureteral neoplasms of mesodermal origin. As an intrinsic cause of ureteropelvic junction obstruction (UPJO) they are very uncommon. Excretory urography and diuretic renography used by many urologists to diagnose a UPJO may not detect the ureteral polyp. We present a case of ureteropelvic junction obstruction caused by a fibroepithelial polyp, which ...
