DIAGNOSIS OF URACHAL ANOMALIES IN INFANCY AND CHILDHOOD BY CONTRAST FISTULOGRAPHY, ULTRASOUND AND CT

From 1981 to 1989 seventeen cases of pediatric patients with urachal remnants have been treated at the Fukuoka Municipal Children's Hospital (2 patent urachus, 5 urachal cyst, 9 urachal sinus, 1 urachal diverticulum). The cases of patent urachus were discovered in the neonates due to a urine discharge from the umbilicus; in the older children, cysts or sinuses accompanied by an infection led to the diagnosis of the urachal anomaly. In 8 of 11 cases, fistulography established the diagnosis. In 9 of 12 cases, ultrasound imaging was diagnostically successful, as was CT in all 3 cases that were given scans.
