Due to the anatomical position of the seminal vesicles being adjacent to the prostate, inflammation affects the seminal vesicles in about 80% of cases, and therefore, this condition is also known as prostatovesiculitis. Because prostatitis is difficult to cure and prone to recur, many chronic prostatitis patients may carry the inflammation into old age.
Prostatitis is a common disease among young and middle-aged men. According to statistics, it accounts for about one-quarter of urology outpatient cases. Patients with prostatitis may have no symptoms at all, or they may experience persistent or recurrent discomfort in the genitourinary system. Due to the anatomical location of the seminal vesicles being adjacent to the prostate, inflammation affects the seminal vesicles in about 80% of cases, so the disease is also called prostatovesiculitis. Because prostatitis is difficult to cure and prone to recur, many chronic prostatitis patients may carry the inflammation into old age. So, why does the prostate become infected?
The infection pathways of the prostate can be roughly divided into three aspects:
1. Direct spread through the urethra: This is a relatively common route of infection. Bacteria enter the urethra through the urethral opening, then invade the prostate gland via the prostatic ducts, causing acute or chronic prostatitis. It's worth noting that gonococcal urethritis is an important cause of prostatitis. With the rapid development of gonorrhea in recent years in our country, it has become an important cause of chronic prostatitis. Prostatic hyperplasia or the presence of stones can deform and twist the prostatic portion of the urethra, causing congestion and difficulty in urination, and reducing the immunity of the mucosa of the prostatic portion of the urethra against non-pathogenic bacteria originally present in the urethra, thus making it susceptible to prostatitis. Excessive sexual activity or over-masturbation can cause repeated congestion of the prostate, inducing prostatitis. Catheterization or urethral instrument examination can introduce bacteria into the urethra, causing prostatic infection.
2. Infection through blood circulation: Pathogenic bacteria from infections in other parts of the body can reach the prostate through the bloodstream and cause prostatitis. Common examples include bacteria from skin, tonsil, dental caries, respiratory tract, or intestinal infections entering the blood and invading the prostate.
3. Lymphatic infection: This is relatively rare but can occur when nearby infections such as in the rectum, colon, bladder, or urethra spread to the prostate through lymphatic channels.
The classification of prostatitis is relatively complex. Apart from ordinary bacterial prostatitis which can be divided into acute and chronic prostatitis, there are also specific types of prostatitis including those caused by gonococcus, tuberculosis bacillus, syphilis spirochetes, fungi, and parasites (such as trichomonads), viral, mycoplasma, chlamydia infections, granulomatous prostatitis, prostatic pain, and prostatic congestion.
