If a colovesical fistula is suspected, a urinalysis may reveal red or white blood cells. However, inflammation and infection due to diverticulitis adjacent to the ureters or the bladder may be the source of these cells. A urine culture may confirm sterile pyuria due to inflammation versus polymicrobial infection in the case of a fistula.
