Y-type urethral duplication: an unusual variant of a rare anomaly

Abstract

Urethral duplications are rare anomalies. We present a 3-year-old continent boy passing urine since birth per anus while voiding from penis. Micturating cystourethrogram, retrograde urethrogram and cystoscopy revealed a Y connection between the posterior urethra and anal canal. The accessory channel was excised by a perineal approach. Histopathology revealed that the tract was lined by transitional epithelium, proving that it was indeed a case of urethral duplication; hence, we suggest that all urethroanal fistulas are not variants of anorectal malformations. Certain of these fistulas should be considered as variants of Y-type urethral duplication even if the orthotopic urethra is normal.

Y-Type Urethral Duplication: A True Variant of the Anomaly or a Misnomer?

“…1-4,7-20 Urethrograms of 15 cases were includ-ed in these reports that were revised by the authors as well (►Table 1). [1][2][3][4][7][8][9][10][11][12] We report the following observations concerning the congenital connection between the urinary tract and the external anal orifice in the male:…”

“…1b and 2a) and in the revised urethrograms of previous reports as well. [2][3][4][7][8][9][10] The posterior urethral kink may reflect the presence of tension across the intercommunicating urethroanal channel. This tension was also noticed during the excision of the accessory channel, which was followed by immediate deep retraction of its ends (►Fig.…”

Y-type Urethral Duplication with Rectal Implantation of the Urethra in a Boy with Long-gap Esophageal Atresia: A Case Report

“…Usually, single case reports and few case series were published. [11][12][13][14][15] We report a case of newborn male with multiple congenital anomalies and Y-type II a urethral duplication with rectal implantation.…”
