Thirty-three infants with anorectal malformations were reviewed for the detectability of fistula as well as associated anomalies by radiographic examinations. In five cases the simple abdomen and invertogram showed air in the bladder and vagina, indicating rectourethral and vaginography was 63%. Sixteen cases(50%) had one or more associated anomalies. Unilateral renal agenesis, hemivertebrae and/or hypoplasia of the sacrum were the most common associated anomalies. Regardiless of the type of anorectal malformation, high incidence of associated anomalies was noted in female infants. All neonates with anorectal malformations should be subjected to plain radiography before a contrast study for the detection of associated spinal anomalies and air in the genitourianry system.
