Abstract
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.
