The main manifestations of cystitis in adult women are urinary tract irritation, i.e. frequent micturition, urgency, pain, leucocyturia, occasionally hematuria, even gross hematuria, and discomfort in the bladder area. Generally, there is no obvious symptom of systemic infection, but a few patients may have low back pain, low fever (generally no more than 38 ℃), and the white blood cell count often does not increase. More than 30% of cystitis is self limited and can be cured within 7-10 days.
