A Case of Urethral Duplication Arising from the Posterior Urethra to the Scrotum with Urinary Stone in a 6-Year-Old Male

Abstract

Urethral duplication is a rare congenital anomaly. We report a 6-year-old male with type IIA2 (Y-type) using Effmann's classification. The accessory urethra, in which a urinary stone existed, arose from the posterior urethra to the scrotum. Because of recurrent urinary tract infection and urinary discharge from the accessory urethra, surgical removal of the accessory urethra through a scrotal incision was performed. At 7-month postoperative follow-up the patient was completely free from urinary incontinence and urinary tract infection.

<p>Complete Urethral Duplication: Case Report and Literature Review</p>

“…18 Mori et al described a case treated with complete excision of the accessory urethra from the normal urethra in a rare type IIA2 (Y-type) patient who had an accessory urethra that opened into the scrotum. 19 Abou Zeid et al 6 chose treatment options according to the classification he proposed.…”

Urethral duplication in a child with VATER association

“…One out of three patients has an associated vesicoureteric reflux (VUR). 3 In type I which is also the most common type, the urethra is partially duplicated and is almost always asymptomatic, requiring no further treatment. In type II, complete duplication of the urethra is observed.…”

A rare case of congenital Y-type urethral duplication

“…Urethral duplication is a rare congenital malformation and only 325 cases have been reported in the literature to date [1,2]. It is more frequently seen in males and is often associated with genitourinary and gastrointestinal anomalies [1].…”

“…It is more frequently seen in males and is often associated with genitourinary and gastrointestinal anomalies [1]. The clinical presentations vary from being asymptomatic to urinary tract infections (UTI), double stream or incontinence according to the anatomical variant present [1,2].…”

“…It is more frequently seen in males and is often associated with genitourinary and gastrointestinal anomalies [1]. The clinical presentations vary from being asymptomatic to urinary tract infections (UTI), double stream or incontinence according to the anatomical variant present [1,2]. Although a number of theories have been proposed to describe the embryologic development of urethral duplication, the etiology and mechanism of this disorder is unknown [2].…”
