Chronic cystitis is a recurrent bladder infection. Women get it more often than men. The main symptoms are recurring pain when peeing and a constant urge to go to the bathroom. Acute cystitis is usually caused by bacterial infection, but they can also be caused by an underlying disease (e.g. diabetes) .
About one third of the women who have acute symptoms of cystitis have sterile urine or some other cause for the symptoms. Many diseases of the urinary tract produce significant pyuria without bacteriuria, including staghorn calculi, tuberculosis, and infections caused by Chlamydia and Mycoplasma spp.
