Benign Urethral Polyps

Abstract

Ten male patients presented between 1985 and 1991 with benign urethral polyps. This lesion is believed to represent a developmental error in the invagination process of the submucous glandular material of the inner zone of the prostate. The clinicopathological features of the condition are discussed and the literature is reviewed.

Fibroepithelial Polyp of the Lower Urinary Tract in Adults

“…11 However, cases have also been reported from the second to fourth decades. 6,7,9,12,14,16,17 Their main clinical manifestations are urinary obstruction, urinary hesitancy, dysuria, enuresis, hematuria, infection, and flank pain. They are usually diagnosed by cystourethrography or cystoscopy and are treated by TUR, following which the lesion does not usually recur.…”

Urethral polyp in neonate: a rare occurrence

“…They may arise as a result of developmental error in the invagination process of the glandular material of the inner zone of the prostate [4]. Posterior urethral polyps are considered vestiges of Mqller's tubercle that fail to regress [5], whereas anterior urethral polyps have all arisen from dorsal 12-o'clock position deep in the bulbar urethra [6].…”

MR findings of prostatic urethral polyp in an adult

“…Prostatic urethral polyps, which were first described by Henry Thompson in 1855 [6,7], are quite rare abnormalities and occur more often in children than in adults [1,2]. They have been attributed to hyperplasia or evagination of the underlying prostatic ductal epithelium or a metaplastic conversion of the overlying transition epithelium [8,9].…”
