Abstract
Normally, the urinary system is completely separated from the alimentary canal.
Enterovesical fistula (EVF) is an abnormal communication between the intestine and the bladder.
Based on the bowel segment involved, it can be divided into four main categories: colovesical (the commonest form, usually between sigmoid colon and bladder dome), rectovesical, ileovesical and appendicovesical (accounting for less than 5% of cases).
Enterovesical fistulae are an uncommon complication of both benign and malignant processes. The diagnosis of EVF may, however, be challenging. With a high index of suspicion for fistula formation in patients presenting with symptoms suggestive of abnormal communication between the intestine and the bladder, appropriate radiological investigation can lead to a significant reduction in morbidity. Recognition of a fistulous tract, delineation of its course, and characterisation of its complexity affect the EVF management.
In this respect, cross-sectional imaging with CT and MRI remains an ideal modality option in patients with enterovesical fistulae. Management of EVF is mainly dependent on the underlying pathology, site of the bowel lesion, and patient’s preoperative performance status. Surgical strategy is a preferred option in most of the cases.
