Acute prostatitis urinary symptoms: burning pain during urination, urgency, frequency, dribbling and purulent urethral discharge. Bladder neck edema can lead to poor urination, thin or interrupted urine flow, and in severe cases, urinary retention. Acute prostatitis is a common infectious disease of the male genitourinary tract, and the causative organisms are mainly E. coli, accounting for about 80%. What are the causes of acute prostatitis? 1, lymphatic infection Lymphatic infection is relatively rare, lower urinary tract infections and inflammation of the colon and rectum can be infected through the lymphatic channels and the prostate, resulting in inflammation. 2, bloodstream infection The pathogenic bacteria from other parts of the body can reach the prostate through blood circulation and cause prostatitis. Bacteria from skin, tonsils, dental caries, respiratory or intestinal infections can enter the bloodstream and invade the prostate. 3, direct spread Direct spread is a more common way of infection. When men urinate, bacteria enter the urethra through the urethral orifice, and then invade the prostate gland through the prostate duct, causing acute or chronic prostatitis. Hypersexuality or excessive masturbation can cause repeated congestion of the prostate gland, which can lead to prostatitis. Catheterization or urethral instrumentation can bring bacteria into the urethra and cause prostate infection. Prostatic hyperplasia or the presence of stones can reduce the immunity of the urethral mucosa of the prostate against non-pathogenic bacteria that can coexist peacefully in the urethra, which can also lead to prostatitis.
