Urachal Anomalies in Children: A Single Center Experience

The objective of this study is to define optimal diagnosis and treatment strategies for patients with urachal anomalies in the pediatric age group. The medical records of 21 children who had undergone surgery for urachal anomalies at Severance Hospital, Yonsei University College of Medicine from January 1990 to April 2005 were reviewed. The subjects included 14 males and 7 females (M:F 2:1). The four types of urachal anomalies confirmed were a urachal cyst in 10 patients (47.6%), a patent urachus in 6 (28.6%), a urachal sinus in 4 (19.0%) and a urachal diverticulum in 1 (4.8%) patient. The most common presenting complaint was umbilical discharge (n = 10, 40.0%), followed by abdominal mass (n = 9, 36.0%). Urachal anomalies were diagnosed by ultrasonography in 18 patients, and 7 of them were additionally examined by computed tomography. The remaining patients were diagnosed solely by surgical exploration. Excision was performed in all patients and was supplemented by partial cystectomy in three. Umbilical discharge was the most common clinical manifestation in our patients, suggesting that ultrasonography should be performed in patients with umbilical discharge to differentiate urachal anomalies. We found the most common anomaly to be the urachal cyst, and all patients were successfully treated by surgical excision.

Clinical Analysis of Urachal Anomalies

PURPOSE: Although relatively rare, urachal remnants manifest as a large number of diverse disorders, which can lead to a high misdiagnosis rate. Because of the many clini-cal pre-sentations, there are no uniform guidelines for the evaluation and treatment of urachal remnants. We report our experi-ence with urachal anomalies in an attempt to establish an optimal diagnostic and treatment modality. METHODS: Fifteen patients (6 males and 9 females), who had undergone surgery for urachal anomalies from December 1988 to July 2004, were analyzed retrospectively. RESULTS: The patients' age ranged from 1 day to 71 years old. The 3 variants of urachal anomalies included a patent urachus in 1 patients (7%), urachal sinus in 5 (33%), and an urachal cyst in 9 (60%). The presenting complaint was a low abdominal mass in 6 patients, abdominal pain in 5, periumbilical discharge in 3, fever in 3, and periumbilical urination in 2. Four combined anomalies were observed in 4 patients. The diagnostic evaluation included fistulography in 3 cases, sonography in 12, and CT in 3. Excision was performed in 12 patients. CONCLUSION: Urachal anomalies most often present in infancy, and can be diagnosed and treated with certainty if a good physical examination and proper imaging studies are performed. Surgical excision is the treatment of choice for urachal anomalies.

A Clinical Observation of Children with Urachal Anomalies

PURPOSE: Urachal anomalies are rare but are known to develop several complications, especially infection. Moreover, uniform guidelines for management have not been presented because of the variable clinical characteristics of these anomalies. The purpose of this report is to review our experience with urachal anomalies and attempt to determine the optimal management. METHODS: We retrospectively reviewed the records of fourteen children with a variety of urachal anomalies who had been treated from January 1996 to June 2005 at Dong Kang General Hospital. RESULTS: The age distribution of the patients(mean age; 3.8 years) was six neonates, one infant, five preschool-age and two school-age children. The male to female ratio was 1:1. Six cases of urachal cyst, four cases of patent urachus, two cases of urachal sinus and two cases of urachal diverticulum were found. Three patients with patent urachus and one with urachal cyst had hydronephrosis. Other associated anomalies included an inguinal hernia in one patient with urachal sinus and a vesicoureteral reflux in one patient with urachal diverticulum. As a first-line diagnostic tool, high-resolution ultrasound examination was performed in thirteen cases and computed tomography in one case. Surgical excision was performed in nine patients with urachal anomaly. Five cases out of six neonatal cases experienced spontaneous improvement during a three-month follow up period. Due to frequent infection of the umbilicus, surgical excision was performed on one neonate with urachal sinus. CONCLUSION: All patients with urachal anomalies should undergo investigation for associated anomalies. The neonate with urachal anomalies, especially patent urachus, do not require surgical excision unless the patient has multiple episodes of recurrent infection.

Clinical Analysis of Urachal Anomalies

PURPOSE: Although urachal anomalies are rarely observed clinically, they often give rise to a number of problems, such as infection and late malignant changes. Because of variable clinical presentations, uniform guidlines for evaluation and treatment are lacking. The authors discuss the problems involved in both the diagnosis and the treatment of these anomalies. METHODS: We retrospectively analyzed 15 patients (9 males and 6 females) who had undergone surgery for urachal anomalies from July 1995 to December 1999. RESULTS: The age distribution ranged from 14 days to 38 years old, and the male to female ratio was 1.5:1. The 4 variants of urachal anomalies included a urachal sinus in 7 patients (47%), a urachal cyst in 4 (27%), a patent urachus in 3 (20%), and a bladder diverticulum in 1 (6%). The presenting complaint was periumbilical discharge in 6 patients, fever in 5, umbilical granuloma in 4, low abdominal mass in 3, and low abdominal pain in 1. Eight combined anomalies were seen in 7 patients; 2 umbilical hernias, 1 inguinal hernia, 1 hydrocele, 1 urachal vessel anomaly, 1 vesicoureteral reflux, 1 hydronephrosis, 1 Hirschsprung's disease, and 1 hypertrophic pyloric stenosis. Ultrasound examination disclosed a cyst or a sinus in 5 patients, and CT was performed in 1 case. Excision was performed in all patients, and there was no postoperative complication or recurrence. CONCLUSION: Urachal anomalies most frequently present in infancy or childhood, and the initial presentation is umbilical discharge with infection. Furthermore, the large number of associated genitourinary and gastrointestinal anomalies suggests that a complete work-up for these conditions should be performed. Definitive surgical excision appears to be appropriate for most patients.
