To determine whether one has prostatitis, it is necessary to make a comprehensive judgment based on symptoms and relevant examinations. Prostatitis is divided into acute prostatitis and chronic prostatitis. Acute prostatitis tends to be severe and is mainly characterized by frequent, urgent, and painful urination. Patients may also experience pain and discomfort in the pubic and perineal areas. Due to the swelling of the prostate compressing the urethra, most prostatitis patients will have difficulty urinating, a thinning urine stream, or even intermittent urine flow. Examination of the patient's urine generally shows an increase in white blood cells. Chronic prostatitis has a longer course and also presents symptoms of frequent, urgent, and painful urination, with a white discharge dripping from the urethral opening after urination. Examination of the patient's prostate fluid generally shows abnormal changes, such as an increase in white blood cells in the prostate fluid.
