Prostatitis is one of the common diseases among adult men. Although it is not a direct life-threatening disease, it seriously affects the quality of life of patients. Acute prostatitis is an acute infectious disease localized in the prostate gland with obvious symptoms of lower urinary tract infection and systemic symptoms such as chills, fever and myalgia, elevated white blood cell count and even pus cells in the urine and prostate fluid. Chronic prostatitis is a group of diseases characterized by pain or discomfort in the pelvic region, abnormal urination and other symptoms in the prostate gland under the action of pathogens or (and) certain non-infectious factors. Clinically, it is often classified as: 1. Acute bacterial prostatitis: has an acute onset and may manifest as a sudden febrile illness with persistent and obvious symptoms of lower urinary tract infection, elevated white blood cell count in the urine, and positive bacterial culture in the blood or (and) urine. 2. Chronic bacterial prostatitis: has recurrent symptoms of lower urinary tract infection lasting more than 3 months, prostatic fluid (EPS)/seminal fluid/ The number of leukocytes in the third cup of urine (VB3) is elevated, and the bacterial culture result is positive. 3. chronic non-bacterial prostatitis/prostatodynia: the most common type of prostatitis, with long-term, recurrent pain or discomfort in the pelvic region lasting more than 3 months, which can be accompanied by varying degrees of urinary symptoms and sexual dysfunction, seriously affecting the patient’s quality of life; EPS/ semen/VB3 bacterial culture The results are negative. 4. Asymptomatic prostatitis: no subjective symptoms, only evidence of inflammation found during examinations concerning the prostate (EPS, semen, prostate tissue biopsy and pathological examination of prostatectomy specimens, etc.). The treatment plan varies according to the different clinical subtypes, but the general treatment principle is: the first two subtypes should be adequate, reasonable and full course of antibiotics and symptomatic supportive treatment, the third subtype should be empirical trial of antibiotics and symptomatic supportive treatment, the last subtype can be clinically observed and no special treatment for the time being.
