Benign Ureteral Tumors

Abstract

The diagnosis of benign ureteral polyps should be considered especially in patients younger than 40 years with filling defects of the proximal ureter on the intravenous pyelogram (IVP). The excellent results of conservative organ-saving surgery (open resection, ureteroscopic resection, laser coagulation) require precise diagnostic management preoperatively in these patients.

A Patient with Fibroepithelial Polyp of the Ureter—A Rare Condition Mimicking Malignancy: A Case Report

“…These polyps are thought to be either congenital slow-growing lesions or lesions that develop as a result of chronic urothelial irritants, such as infection, inflammation, or obstruction. Other benign lesions of the upper urinary tract include endometriomas, fibromas, leiomyomas, granulomas, neurofibromas, hemangiomas, and lymphangiomas [5, 6]. …”

Laparoscopic Approach to a Rare Cause of Ureteropelvic Junction Obstruction in a Child: Ureteral Polyp

“… 13 14 15 Conversely, Sun et al figured out in their study that strictures might be cause of over vaporization and Kiel et al mentioned the risk of recurrence due to incomplete resection of tumor. 4 15 24 Bartone et al speculated that resecting the polyp without base might cause obstruction and recurrence. 25 On the other hand, Adey et al underlined the importance of dismembered pyeloplasty whereas polyps might have been missed, if spiral flap or Y–V pyeloplasty is performed.…”

Multiple, Bilateral Fibroepithelial Polyps Causing Acute Renal Failure in a Gastric Cancer Patient

“…Fibroepithelial polyps (FEPs) are the most common nonepithelial tumor and originate from mesodermal elements (1, 2). They have a fibrous core covered by normal urothelium and are smooth-margined, and cylindrical, sessile, or even frond-like (3).…”

“…Ureteral FEPs are usually located in the proximal third of the ureter, and are predominately on the left side, where about 70% of such lesions occur (3, 4). They are usually solitary, and reports of multiple, bilateral polyps are extremely rare (2). We report the seventh case of bilateral FEPs, which was diagnosed by ureteroscopy and proven by biopsy.…”
