A Rare Cause of Macroscopic Hematuria: Ureteral Fibroepithelial Polyp: A Case Report

Fibroepithelial polyps are rare, benign, non-epithelial tumors of the urinary system. They can occur throughout the entire urinary system, including the renal pelvis, ureter, bladder, and urethra, which are lined with urothelium. These polyps originate from the stromal structure, formed by the combination of mesodermal and urothelial cells. The most common clinical complaint of patients with fibroepithelial polyps is unilateral flank pain. In some cases, this pain may be accompanied by hematuria, dysuria, and pollakiuria, which are irritative lower urinary tract symptoms. In this case report, a case of a giant ureteral fibroepithelial polyp in a patient who was admitted to our clinic with macroscopic hematuria and left flank pain was presented. Following the diagnosis of a giant polyp in the left ureter, we treated the patient with endoscopic ablation using a Holmium-YAG laser device under ureteroscopy guidance.
