Surgery for anomalies of the urachus

Thirty-five children with anomalies of the urachus which have required surgical management have been encountered in this institution over a 20-year period. Of these 35, 19 were classified as patent urachus, 12 as urachal cyst, and 4 as urachal sinus. All cases were treated by excision or drainage. There was one death. Gastrointestinal and other genitourinary anomalies were commonly seen in these patients. Intravenous pyelography was helpful in identifying unsuspected associated genitourinary anomalies while cystography was not. Investigation of the gastrointestinal tract does not appear to be warranted in the absence of symptoms.
