Benign fibroepithelial polyps causing ureteropelvic junction obstruction in a child: A case report

Elaheh Shahab, SeyyedMohammad Ghahestani


The fibroepithelial polyps of the ureter are benign tumors derived from mesenchymal tissue, which can rarely cause obstruction of the ureteropelvic junction in children. Because the fibroepithelial ureteral polyps are difficult to accurately diagnose preoperatively, multiple diagnostic procedures are required for diagnosis. We report the case of a 5-year-old boy with intermittent gross hematuria, left flank pain and hydronephrosis diagnosed with fibroepithelial polyp by ultrasonography. We performed ureteroscopy to confirm the diagnosis and localize the polyp, which led us to surgical exploration and dismembered pyeloplasty due to the multiplicity and large size of the polyps. At the 18-month follow-up, the patient is recurrence-free.
