Abstract

The embryological and anatomical features of urachal anomalies have been well defined. Because of the variable clinical presentation, uniform guideline for evaluation and treatment are lacking. Although urachal remnants are rarely observed clinically, they often give rise to a number of problems such as infection and late malignant changes. Therefore, a total assessment of the disease with a particular focus on embryology, anatomy and clinical symptoms, as well as the most advisable management, is called for. Twenty six patients with urachal remnants were treated at the Department of Pediatric Surgery from August 1980 to June 1998. Of these 26, 9 were classified as patent urachus, 11 as urachal sinus, 4 urachal cyst, 1 urachal diverticulum and 1 alternating sinus. The group consisted of 11 males and 15 females. The age distribution was 20 neonates, 3 infants, 2 preschoolers and 1 adult. Infection was the most frequent complication and Staphylococcus aureus was the predominant causative microorganism. Fistulogram was performed in 4 cases and ultrasound examination disclosed cysts or sinus in 7 cases. Excision was performed in 24 patients and incision and draniage in 2 cases as a primary treatment. There was no postopreative complication or recurrence.
