Ureteral Polyp Managed by Endoscopic Techniques

Abstract

Fibroepithelial polyps (FEPs) are rare benign tumors of mesodermal origin. They are found in the ureters 85% of the time, with the remainder located in the renal pelvis and occasionally the bladder. FEPs can present as flank pain, lower abdominal pain, and/or gross hematuria. Previous literature reports management of these benign lesions using open surgical techniques, laparoscopic techniques, and endoscopic management. In this article, the authors present their pure endoscopic management of a large ureteral polyp and a review of the current literature outlining the etiology, clinical presentations, and management techniques for FEP of the ureter.
