A Fibroepithelial Urethral Polyp Protruding into the Base of the Bladder: Sonographic Diagnosis

Abstract

A case of congenital urethral polyp in a 10-month-old boy is presented. These rare congenital tumors can lead to urinary retention, hematuria, urinary tract infections, hydronephrosis and hydroureter. Traditionally the diagnosis was based either on voiding cystourethrography or cystoscopy. The sonographic features of these polyps have only been reported in a few cases in the past. This modality is not infrequently the imaging procedure of choice in the work-up of children with signs and symptoms related to the urinary system. In the case presented herein the polyp was demonstrated initially by sonography as a soft tissue mass arising at the base of the urinary bladder. The differential diagnosis of these lesions is presented.

A huge fibroepithelial polyp of the bladder neck in an infant

“…Çocukluk çağında erkeklerde daha sık olduğu bildirilmiştir (1,2,7,8) . Alt üriner sistem polipleri tipik olarak bir sapla prostatik üretraya tutunan hareketli lezyonlardır.…”

“…Alt üriner sistem obstrüktif bulguları olan çocuklar-da genitoüriner sistemin ultrasonografi, kontrastlı radyolojik incelemeler ve endoskopik çalışmalarla daha fazla değerlendirilmesi ile alt üriner sistemin polipleri daha fazla ortaya konulmaya başlanmıştır (2,5,8) . Prostatik üretra ve mesane boynunda görüntü-leme ve endoskopik yöntemlerle karşılaşılan polipoid lezyonlar malign neoplazmları düşündürebilmekte-dir.…”

Pólipo fibroepitelial de uretra en un adulto

“…El diagnóstico se establece mediante la cistouretrografía miccional (defecto de repleción en la uretra prostática), la ecografía (lesión polipodea que protuye desde el cuello vesical en la base de la vejiga) 9 o mediante la visualización directa por uretrocistoscopia.…”

MR findings of prostatic urethral polyp in an adult

“…Typical presentations include hematuria and varying degrees of irritative and obstructive voiding symptoms [3]. Previous reports have reported radiological findings including computed tomography, transrectal sonography, voiding cysto-urethrography, and urethroscopy [4,5], but to our knowledge, MR imaging findings have not been previously described. In this case, we report MR imaging findings and correlate them with pathologic findings, and we review relevant articles in the literature.…”

“…Based on a review of the diagnostic and pathological findings of previous reports of prostatic urethral polyps in the literature, transrectal sonography shows an echogenic mass in the urethra, voiding cysto-urethrography and intravenous pyelography show a well-defined filling defect of the bladder or the urethra, and urethroscopy or cystoscopy show a polypoid mass often with a stalk connected to the prostatic urethra surface [4].…”
