title: Multiple, bilateral fibroepithelial polyps causing acute renal failure in a gastric cancer patient.
abstract: We report a case of primary fibroepithelial polyps (FEPs) in the middle of both ureters in a patient with advanced gastric cancer and acute renal failure. Ureteral FEPs are rare benign lesions, and multiple, bilateral lesions are extremely rare. To our knowledge, this report is the seventh case of bilateral FEPs in the literature. Our case has clinical implications because FEPs should be considered as a cause of ureteral obstruction inducing acute renal failure in advanced gastric cancer.
