Tests found pus and fecal matter in my urine. i have gotton several infections since my bought with diverticulitis .having lower back and stomach pain?

Red Flag Warning: Pus and Fecal matter in the urine, in the setting of prior diverticulitis, infers a "rectovesicular fistula". This happens when the inflamed colon irritates and ulcerates into the bladder. An opening is formed that allows stool to pass into the bladder. Your physician might recommend a CT scan of the belly or a cystoscopy (looking into the bladder). Definitely a potentially serious problem.
