Bladder Neck

Bladder neck: functions, structure and diseases

The bladder neck, also known as the cervix vesicae urinariae or simply the bladder neck, is an important anatomical structure in the human urinary system. It performs several key functions and can be susceptible to various diseases. In this article we will look at the structure of the bladder neck, its functions and some common diseases.

The structure of the bladder neck is quite simple. It is a narrow tube connecting the bladder to the urethra. The neck of the bladder is cone-shaped and is usually located at the bottom of the bladder. Its walls are composed of a special type of epithelium and muscle that ensure its functionality.

One of the main functions of the bladder neck is to maintain control over the flow of urine from the bladder. It serves as a kind of valve that prevents the reverse flow of urine from the urethra into the bladder. Thanks to this function, the bladder neck helps maintain normal urination and prevents unwanted urinary incontinence.

In addition, the bladder neck plays an important role in the female reproductive system. In women, the cervix of the bladder is connected to the cervix. It is the passage between the vagina and the uterus and is the entrance to the cervix. During sexual intercourse, the bladder neck acts as a barrier that protects the uterus from infections. It also plays an important role in the birth process by expanding to facilitate the passage of the baby through the birth canal.

Despite its importance, the bladder neck can become the site of various diseases. One of the most common diseases of the bladder neck is cystitis - inflammation of the mucous membrane of the bladder. Cystitis can cause unpleasant symptoms such as painful urination, a strong urge to urinate, and general malaise. Other diseases associated with the bladder neck include various types of tumors and infections.

Diagnosis and treatment of bladder neck diseases usually requires consultation with a urologist or gynecologist. The doctor may perform a physical examination, including palpation of the bladder neck, and order additional tests, such as urography or cystoscopy. Treatment depends on the specific disease and may include anti-inflammatory drugs, antibiotics, surgery, or other methods to treat the cause of the disease.

In conclusion, the bladder neck plays an important role in the human urinary and reproductive systems. It functions to control urination and is an important component of the female anatomy. Various diseases of the bladder neck can cause unpleasant symptoms and require medical intervention. If you experience any problems or symptoms related to your bladder or bladder neck, it is important to see a qualified healthcare professional for diagnosis and treatment.
