The treatment of colovesical fistula is surgical as well as conservative, which mainly involves the administration of antibiotics, catheterization, and intravenous nutrition. The preferred treatment for colovesical fistula is surgery, which can be open or laparoscopic. Patients are given anti-infective treatment after surgery. If the patient cannot tolerate surgery, or if there are patients with inoperable cancers, then conservative treatment is given, with treatments such as nutrition given through a vein so the bowel can rest; antibiotics such as levofloxacin and combined with corticosteroids such as methylprednisolone to control the infection; and insertion of a catheter into the bladder to drain fluids that may be seeping from the colon into the bladder. The goal of conservative treatment is to allow the fistula to close and heal on its own; however, surgery may still be necessary in cases where the fistula does not heal on its own. It is recommended that the patient undergoes a detailed examination and the doctor evaluates the patient’s physical condition and decides on the treatment.
