Abstract

It is well known that infants born with imperforate anus have many other associated congenital anomalies, especially urogenital anomalies. Between 1985 and 1990, 50 infants and children with imperforate anus were evaluated for associated urogenital malformations according to the international classification on imperforate anus. The overall incidence of urogenital malformations in these patients was 28 percent. Among them, urogenital malformations were found in 50 percent of the patients with high or intermediate types of imperforate anus. Unilateral renal agenesis was the most frequently encountered urinary tract anomaly. In 10 cases, all of which were boys with high or intermediate types of imperforate anus, there was a fistulous connection between the blind end or the rectum and the urethra or bladder. The incidence of associated urogenital malformation was significant, especially in the high and intermediate types of imperforate anus. Therefore, we recommend that a careful examination should be done for the early diagnosis and treatment of associated urologic anomalies in infants and children with imperforate anus because considerable morbidity and mortality may occur due to delayed recognition of occult urologic problems in these infants.
