The symptoms of acute cystitis include frequent urination, urgent urination, and painful urination. It may be accompanied by gross hematuria, cloudy urine, and lower abdominal pain.
The main cause of acute cystitis is the retrograde infection of bacteria from the perineum. The common bacteria are Gram-negative bacilli, among which Escherichia coli is the most common.
The main treatment is a 3-day therapy, taking oral antibiotics for 3 days. Currently, the relatively sensitive antibiotics are levofloxacin, amoxicillin clavulanate potassium, or clarithromycin.

However, in general, some special patients cannot be completely cured after the 3-day oral therapy and still need to extend the use of antibiotics for 7 to 10 days or 14 days.
It is best to have a urine test and a blood test at the hospital when considering acute cystitis.
