How long is the female urethra?

Women's physical health is the most important thing, but some women are prone to disease problems. The female urethra is a part of the body that is often prone to inflammation problems. Female urinary tract infection should be a more serious bacterial infection, so the genitals need to be cleaned frequently, especially the urethra. But how long is the female urethra?

Female urethra

The female urethra is very short, only 2.5-5 cm long, with an average of 3.5 cm, and a diameter of about 8 mm. It is easy to expand and can reach 10-13 mm. It has no bends and starts from the bladder neck and runs downward and forward to the urethral opening behind the pubic symphysis in front of the vagina.

composition

The female urethra can be divided into three parts: the upper tissue structure and the bladder neck.

The female urethra is consistent. The circular muscle of the bladder neck is continuous with the circular muscle of the upper urethra and is particularly thickened at the neck, which is different from the sphincter of the male bladder neck, which is composed of the left and right middle and outer layer muscle fibers crossing each other. Female internal sphincter,

It is composed entirely of circular smooth muscle fibers that surround the entire bladder neck and upper urethra. Therefore, the action of the internal sphincter is particularly strong in women. In the middle urethra, there are voluntary circular muscles outside the smooth muscle layer. Although this muscle layer is not very obvious, it also has some external sphincter function. The lower urethra, which is the urethral opening, has no muscles, only two layers of triangular ligament fibrous tissue. In addition, the levator ani muscles, deep perineal muscles and triangular ligament also play an auxiliary role in controlling female bladder urine.

organize

The mucosal epithelium in the middle and outer parts is a quadratic epithelium similar to the vaginal mucosa, and the upper part transforms into the same transitional epithelium as the bladder neck. There is loose tissue between the submucosal layer and the muscle layer, and outside the muscle layer there is a rich venous network tissue, namely the urethral spongy tissue. Urethral glands are abundant in the female urethra, the most prominent of which are the paraurethral glands, which contain columnar epithelium that secretes mucus.

Lymph of the urethra: There are many lymphatic vessels and lymph glands under the urethral mucosa, which drain the lymph to the inguinal and subgastric lymph nodes on both sides.

Blood supply to the urethra: The inferior vesical artery supplies the upper urethra, the vaginal artery supplies the middle urethra, and the internal pudendal artery supplies the lower urethra. The veins return to the bladder, vagina, and pudendal venous plexus.

Physiology of the urethra: The main function of the female urethra is to urinate and secrete mucus; the urethral gland is also an accessory gland that secretes transparent protein-containing mucus, which serves to increase lubrication during sexual intercourse.

27 Why do I have occasional stinging pain in my urethra?

Why do men sometimes have stinging pain in their urethra?

1. Urethritis: Urethritis refers to the invasion of the urethra by bacteria, diseases/viruses and other pathogens, causing inflammation, which in turn stimulates the urethra and affects urination. It is the main cause of painful urination.

2. Prostatitis: The most obvious urethral pain caused by prostatitis is stinging, and the pain is still felt after urination, similar to the feeling of "empty pain"; it is more common in drivers, IT personnel and other people who often sit to work. After men suffer from prostatitis, the pressure in the posterior urethra increases significantly, causing prostate patients to experience symptoms such as painful urination and groin pain.

3. Cystitis: Cystitis is an inflammation that occurs in the bladder area. Most cases are caused by urethral infection, which retrogrades to the bladder. Therefore, cystitis is often accompanied by chronic urethritis. During urination, the bacteria-laden urine in the bladder stimulates the urethra, causing an obvious burning sensation and painful urination.

4. Sexually transmitted diseases such as gonorrhea or genital warts: If you have a history of unclean sexual behavior, and then experience stinging pain when urinating, increased urethral secretions, rashes and bumps on the penis, the most likely problem is a sexually transmitted disease such as gonorrhea or genital warts.

What to do if you have stinging pain in your urethra

Most of the time, men's pain when urinating is caused by disease, and patients need to go to the hospital in time for relevant diagnosis and treatment, find out the cause and make targeted treatment. In daily life, we also need to strengthen dietary regulation and pay more attention to rest. During the recovery process, you need to exercise properly and keep your private parts clean. You should also pay attention to your daily diet and rest. Don't always smoke and drink. Don't hold your urine when urinating. Urinate in time. Drink more boiled water, less carbonated drinks and coffee. Eat more vegetables and fruits, and eat more light and easily digestible foods. It is also helpful.

I believe that everyone already knows why men sometimes experience stinging pain in the urethra, and also knows what diseases cause this symptom. When this disease occurs, men must pay more attention, go to a regular hospital for relevant examinations and symptomatic treatment, and also do relevant nursing work in life.
