The internal os is the inner opening of the cervix where the uterus meets the cervical canal. A stricture in this area means that the opening is narrowed or blocked, usually due to scar tissue or other changes that affect the structure. This condition can interfere with normal uterine functions such as menstruation, fertility, and may cause pain or bleeding.
What is the Internal Os of Uterus Stricture?
- Internal Os: The internal os is the narrow opening at the top of the cervix, which connects the uterus to the cervical canal.
- Stricture: A stricture is a narrowing of a passage in the body caused by scar tissue or inflammation.
When these two combine, the condition is called an internal os of uterus stricture. This means that the normal opening of the cervix is abnormally narrowed, which can affect menstrual flow, fertility, and overall uterine health.
Pathophysiology
Understanding the internal os of uterus stricture involves knowing the structure of the uterus, its blood and nerve supply, and its functions.
Structure of the Uterus and Cervix
- Uterus: A hollow, muscular organ where a fertilized egg implants and develops during pregnancy.
- Cervix: The lower part of the uterus that opens into the vagina. It has two parts:
- Internal Os: The upper, inner opening of the cervix.
- External Os: The lower opening that leads to the vagina.
Blood Supply
- Arterial Supply: The uterus is mainly supplied by the uterine arteries, branches of the internal iliac arteries. These vessels provide the blood needed for the growth, repair, and function of the uterine tissues.
- Venous Drainage: Blood from the uterus is drained by veins that eventually return to the heart.
- Importance: A proper blood supply is essential for healing; any disruption (for example, from surgical procedures or infections) can contribute to scar tissue formation, which may lead to strictures.
Nerve Supply
- Autonomic Nerves: The uterus is controlled by both the sympathetic and parasympathetic nervous systems. These nerves help regulate contractions, blood flow, and secretions.
- Sensory Nerves: Though less prominent, these nerves send pain signals, which is why strictures and associated inflammation can sometimes be painful.
Functions of the Internal Os
- Control of Menstrual Flow: The internal os regulates the outflow of menstrual blood from the uterine cavity.
- Barrier Function: It acts as a gatekeeper during pregnancy, helping to keep the fetus inside the uterus until labor.
- Fertility Role: A properly functioning internal os is important for sperm passage during conception and maintaining a healthy environment for embryo implantation.
How a Stricture Develops
- Scar Tissue Formation: After injury, infection, or surgery, the body can form scar tissue. If this happens at the internal os, it can narrow the passage.
- Inflammation: Chronic inflammation from infections (like tuberculosis or pelvic inflammatory disease) can cause tissue damage and subsequent scarring.
- Congenital Factors: Although rare, some women may be born with a narrower-than-usual internal os.
Types of Internal Os Stricture
While the internal os stricture is generally described by its location, it can be classified based on the cause and severity:
- Primary Stricture: A congenital narrowing that is present from birth.
- Secondary Stricture: An acquired narrowing due to factors such as surgery, infection, or injury.
Some experts also classify strictures by severity (mild, moderate, or severe) based on how much the opening is narrowed, though this is typically determined through imaging or examination.
Causes of Internal Os of Uterus Stricture
Understanding what may lead to an internal os stricture is key. Here are 20 possible causes:
- Post-surgical Scarring: Procedures such as dilation and curettage (D&C) can cause scarring.
- Cesarean Section: Surgical delivery may lead to scarring in the uterus.
- Infections: Pelvic inflammatory disease (PID) or tuberculosis can cause chronic inflammation.
- Endometritis: Inflammation of the uterine lining.
- Radiation Therapy: Pelvic radiation can damage uterine tissues.
- Postpartum Hemorrhage: Severe bleeding after childbirth may require procedures that lead to scarring.
- Myomectomy: Removal of fibroids from the uterus can sometimes lead to scarring.
- Trauma: Physical injury to the pelvic area.
- Uterine Artery Embolization: A procedure to control heavy bleeding may inadvertently cause damage.
- Intrauterine Device (IUD) Complications: In rare cases, IUDs may cause local scarring.
- Autoimmune Disorders: Conditions that cause chronic inflammation.
- Hormonal Imbalances: Hormonal disturbances may alter the healing process.
- Genetic Predisposition: Some women might be more prone to forming scar tissue.
- Chronic Endometriosis: Abnormal growth of uterine lining tissue.
- Intrauterine Adhesions (Asherman Syndrome): A condition marked by scar tissue formation inside the uterus.
- Cervical Procedures: Cone biopsy or loop electrosurgical excision procedure (LEEP).
