Fibroepithelial polyps are the most common benign neoplasm of ureter that originate from mesoderm. These polyps are one of the cause of hydronephrosis by obstructing the ureter. Etiology is not fully defined but there are some publications in the literature suggested that it is due to congenital, infectious, obstructive, traumatic, hormonal imbalances and irritative causes. A 36 years old male patient who admitted with left flank pain and fever. He had a history of endoscopic left ureteric stone surgery 3 years ago. In radiological evaluation with USG and CT, grade 3 hydroureteronephrosis was detected of the left kidney; however no stone was detected. Ureterorenoscopy detected a 5x1 cm ureteral polyp in the distal ureter and punch biopsy confirmed fibroepithelial polyp. We performed laparoscopic excision of the poliphoid segment and ureteroneocystostomy. Although it is rare, fibroepithelial polyp should be considered in hydronephrosis without any urinary stone or malignancy.
