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.
Duplication of the gastrointestinal tract occur any part of the alimentary tract from the tongue to the anus. Male have slightly more predominance than females. Gastrointestinal duplication will have a varied presentation. Ileum and the oesophagus are most commonly involved. Colonic duplication is rare and can present with diagnostic difficulties. Gastrointestinal duplication has presence of well developed coat of smooth muscle, intimately attached to the gastrointestinal tract in the mesentric region and show a common blood supply with the native bowel. Sometime it will have an epithelial lining representing some portion of the alimentary tract.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
