Abstract
Congenital abnormal fistulas between urethra and anorectum or vagina are usually associated with imperforate anus. Congenital recto or anourethral fistulas without anorectal malformations are extremely rare in males and have been called N-type or H-type fistulas1. In many series, this fistulas are not considered under the types of congenital urethra fistula, because these abnormalities have been included as a subtype of anorectal malformation (ARM), even in cases of normally located anus. There is no general agreement about urethral fistula as an identified anomaly, as it may be considered as a sort of urethral duplication or an associated anomaly with other congenital malformations.
