Abstract

Introduction: The fibroepithelial polyps of the posterior urethra (FEP of PU) are rare benign tumors occurring in young boys. They are an uncommon cause of lower urinary tract obstruction in children and can be difficult to diagnose.

Purpose: In the present study, we present our experience with seven boys with FEP of PU along with a literature review.

Methods: We retrospectively identified seven children with FEP of PU presented between 2004 and 2019. The diagnosis was evoqued on the radiological exams and confirmed by endoscopic exploration and histologic study.

Results: The age varied between 6 and 21 months. Dysuria, urinary retention, hematuria and urinary tract infection were the most common symptoms. The diagnostic work-up (sonography, voiding cysto-urethrography, urethrocystoscopy) suggested a polypo lesion originating from the veru montanum. Transurethral resection of the polyp was carried out in all the boys using a pediatric resectoscope. The extraction of the polyp was performed via transvesical trocar or by endoscopic grasping through the ureter. Histology showed the lesion to be a fibroepithelial polyp. All the patients were discharged without complaints. Urinary tract infection was observed one month postoperatively in one case. At follow-up, both boys were cured and urine analyses were normal.

Conclusions: The fibroepithelial polyp of the posterior urethra is a rare cause of urinary retention in childhood and should be considered in differential diagnosis of obstructive lesions.
