title: 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.
