Prostatitis is a type of inflammation that occurs when the prostate gland is stimulated by bacterial infection or non-infectious factors. Mainly, the surface mucosa of the prostate gland is congested and edematous, and the prostate gland is infiltrated with leukocytes. Prostatitis includes acute bacterial prostatitis, chronic bacterial prostatitis, and chronic non-bacterial prostatitis. 1. Acute bacterial prostatitis is mostly caused by retrograde infection of the urethra, such as transurethral instrumentation. It can also be caused by the reflux of infected urine into the prostate from cystitis, acute gonorrheal urethritis and other diseases. The main symptoms include urinary frequency, urinary urgency, painful urination, intermittent urinary line, acute urinary retention, etc. General treatment includes active bed rest, drinking a lot of water and application of antibacterial drugs. 2. Chronic bacterial prostatitis is mainly caused by retrograde infection through the urethra. The main symptoms include changes in urination and white secretion through the urethra after urination, hypogonadism, and so on. The general treatment includes the application of antibiotics, hot water sitz bath, prostate massage and so on. 3. Some non-infectious factors may cause chronic non-bacterial prostatitis. This disease may be related to Chlamydia trachomatis, Mycoplasma, Trichomonas, irregular sex life, interrupted sexual intercourse and other factors. The main manifestations are long-term perineal and lower abdominal pain or discomfort, or frequent and incomplete urination. If the causative agent is chlamydia, drugs such as minocycline may be used. Meanwhile, the treatment also includes hot water sitz bath, prostate massage and so on. To summarize, once prostatitis is detected, go to the hospital immediately and get proper treatment under the guidance of the doctor.
