Case Report: This study reports a 9-year-old boy who presented to our clinic with complaints of unilateral flank pain and macroscopic hematuria. The direct urinary system graph did not show stone formation; therefore, magnetic resonance urography was performed. This revealed a filling defect in the left proximal ureter. On cystoscopy, a polyp was seen in the orifice of the left ureter, extending along the ureter. The polyp was resected by laser ablation and removed from the ureter. Histopathologic examination revealed a fibroepithelial polyp comprising fibrovascular stroma covered with transitional epithelium. Conclusion: Although extremely rare, a fibroepithelial polyp should be considered in the differential diagnosis when a young patient presents with flank pain and macroscopic hematuria. Endoscopic procedures may be the treatment of choice for polyps located in the upper ureter.en10.4274/balkanmedj.2017.1537info:eu-repo/semantics/openAccessGenel ve Dahili TıpArticle353275277Q3WOS:0004332897000112-s2.0-8505533099229843497Q3289690
