Urachal-sigmoid fistula associated with diverticular disease.

BACKGROUND

Urachal anomalies rarely present in adulthood. We report the second known case of urachal-sigmoid fistula associated with diverticular disease.

METHOD: We performed a case report and literature review. We searched MEDLINE and PubMed using the search words "urachus," "urachal fistula," "sigmoid colon" and "diverticulosis."

RESULTS

Our literature review revealed 1 previous report of urachal-sigmoid fistula associated with diverticular disease. We reviewed other publications with respect to pathophysiology, diagnosis and management of urachal disease.

CONCLUSION

Urachal disease that presents in an adult is usually the result of some complication of a urachal anomaly. Various modes of imaging may help confirm the diagnosis, although CT sinography has been recommended and was key in the present case. Management includes eradication of infection and, usually, surgical intervention.
