Symptoms And Signs

You may have symptoms like recurrent urinary tract infections, presence of air bubbles or stool particles in the urine, abdominal pain, urinary frequency and urgency and blood in the urine. As a matter of fact, your physician may advise you to see a urologist surgeon because of recurrent urine infections.

Occasionally, patients with the colo-vesical fistulas can present with the severe urinary tract infections. Basically, this can lead to sepsis which is a serious condition leading to fever, shock and rapid worsening of condition.

Diagnosis And Treatment Of Colovesical Fistula

Common way of diagnosis is by clinical history, physical evaluation and use of certain diagnostic modalities. Most common tests include use of CT scan, colonoscopy and cystoscopy evaluation. Moreover, a CT scan may show air bubbles within the urinary bladder. Also urologist may notice abnormality within the urinary bladder and may be able to visualize the fistula site with cystoscopy procedure.  Recurrent diverticulitis is a very common cause of  colovesicle fistula formation.

Finally, treatment of colovesicle fistula includes use of antibiotics as first modality and control of acute infection. Subsequently, you may need a surgical intervention in the form of resection of the affected colon or a possible bladder repair. Trained colorectal Surgeons can usually perform this surgery using minimally invasive method with the help of a robotic or laparoscopic techniques. Furthermore, a colostomy procedure is an option if there is a risk of anastomotic leak, severe inflammation, scarring, infection with abscess, history of radiation or steroid use. However, surgery usually requires hospitalization.
