title: Endourologic Diagnosis and Robotic Treatment of a Giant Fibroepithelial Polyp of the Ureter.
abstract: 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. A 16-year-old woman with a 12 years history of left lumbar pain was referred to our Center. A computed tomography scan detected a left hydronephrosis with no signs of obstructions at MAG-3 scintigraphy. The endourologic evaluation revealed a giant FEP of the left ureter, which was removed surgically with a videolaparoscopic robot-assisted approach.Conclusion:Considering that conventional radiologic imaging techniques can hardly detect a ureteral FEP, an endourologic study of the urinary tract is mandatory to directly observe the polyp. The mini-invasive treatment of ureteral FEPs is feasible and safe, and should be considered as first option in young patients.
