Urethral polyp in asymptomatic male infant with prenatal hydronephrosis

Abstract

Congenital posterior urethral polyps are rare, benign lesions of the posterior urethra. We report a 1-day-old newborn boy with a solitary fibroepithelial posterior urethral polyp who presented with a history of prenatal mild hydronephrosis, subsequently associated with bladder wall thickening on ultrasonography.
