The presence of leukocytes in prostatitis needs to be determined based on other test results and clinical symptoms to confirm the presence of prostatitis. Prostatitis is usually categorized into two main types, one is bacterial prostatitis and the other is non-bacterial prostatitis. During a routine examination of the prostate fluid, an increase in the number of leukocytes in the prostate fluid may be detected, and therefore leukocytes are usually present in the prostate fluid of prostatitis patients. In order to confirm the diagnosis of prostatitis, it should be evaluated in conjunction with other test results, such as a decrease in lecithin microsomes, a significant increase in neutrophils, an increase in the size of the prostate gland, the presence of infectious bacteria in urine cultures, and the presence of perineal swelling and pain, urinary frequency, urinary urgency, and other symptoms. It is only through the comprehensive evaluation of the above examinations and related clinical symptoms that the existence and severity of prostatitis can be determined, and after the diagnosis has been made, it is necessary to actively cooperate with the doctor to carry out the treatment.
