Fibroepithelial Polyp Associated with Congenital Ureteral Diverticulum: Report of 2 Cases

Abstract

We report 2 cases of a single fibroepithelial polyp in conjunction with ureteral diverticula. Ureterorenoscopy is valuable in the identification of the benign nature of these lesions preoperatively to avert unnecessary nephroureterectomy. The etiology of fibroepithelial polyps remains unknown, although many theories have been proposed. Recent evidence has suggested that these lesions may be a developmental anomaly. Congenital ureteral diverticula also are thought to be of developmental origin. We hypothesize that fibroepithelial polyps and congenital diverticula of the ureter are part of a spectrum of the same developmental anomaly.

Treatment and outcome of fibroepithelial ureteral polyps: A systematic literature review

“…1). [1][2][3] Most papers (56/75) presented a single patient. The largest series was reported by Williams and colleagues 67 and included 15 patients.…”

“…1 In general, benign tumours account for 20% of all ureteral tumours. 2 Most urologists will only infrequently encounter patients with a fibroepithelial polyp. They rely on the medical literature as guidance for treatment and follow-up.…”

Genito-urinary polyps: summary of the 10-year experiences of a single institute

“…Fibroepithelial polyps of the urethra are usually diagnosed during the first decade of the life [20]. The most common presenting symptoms in patients with upper tract FEPs is hematuria [21], although patients may also experience intermittent or recurrent pain thought to be attributed to either torsion or intussuseption of the polyp or intermittent obstruction [22]. Urinary frequency, dysuria, and pyuria are less common findings [1].…”

“…Fibroepitheliome wachsen üblicherwei-se exophytisch-verdrängend und respektieren die Organgrenzen. Eine Metastasierung ist in der Literatur nicht beschrieben [6].…”
