Remnants of urachus in infants and children--the problems of diagnosis and treatment.
A total of 17 cases of remnants of urachus were examined between 1981 and 1989, including 2 cases of patent urachus, 5 of urachal cyst, 9 of urachal sinus, and 1 of urachal diverticulum. A long urachal sinus was considered to be caused by the self-destruction of a cyst. While patent urachus was diagnosed in neonates with urine discharge from the umbilicus, cysts or sinuses accompanied by infection were more often found in older children. Imaging of the burrows was diagnostic in 8 out of 11 cases, ultrasound examination in 9 out of 12, and CT examination in all of 3 cases. Since this condition is frequently accompanied by malformations of the urinary system, attention must be paid to locating the accompanying anomalies. Although primary extraction was performed in 13 cases, the primary treatment of cases with highly infected cysts should be drainage, followed by secondary extraction. Furthermore, caution must be exercised to avoid hemorrhage in cases with dilation of the umbilical artery.
