Urogenital sinus with sinorectal H-fistula - a hitherto undescribed anorectal anomaly.

In a urogenital sinus anomaly, the urethra and vagina are conjoint for a variable distance and the anorectum is usually intact and complete. We report a case of a urogenital sinus with a fistula between the rectum and the sinus. The anomaly was successfully repaired at 2.5 years of age through a midline muscle-splitting incision in the anterior perineum. The anterior wall of the anorectum was divided in the line of the incision in order to deal with the fistula. Repair was done in layers.
