Uterine fibroids, also known as leiomyomas, are benign smooth muscle tumors that develop within the uterine wall. These common gynecologic tumors affect up to 70% of women by age 50 and can vary significantly in size, location, and clinical impact. Understanding their characteristics and management options is crucial for healthcare providers in delivering optimal patient care.
Labeled Anatomical Features:
Intramural Fibroids: Tumors located within the muscular uterine wall. These are the most common type and can cause uterine enlargement and heavy menstrual bleeding.
Subserosal Fibroids: Tumors that develop under the outer uterine covering. These can grow to large sizes and may cause pressure symptoms on adjacent organs.
Submucosal Fibroids: Tumors that develop beneath the uterine lining. These often cause significant menstrual bleeding and can impact fertility.
Fallopian Tubes: The tubular structures extending from the uterus that may be displaced by large fibroids. Their position can affect fertility and cause pain.
Uterine Cavity: The inner chamber of the uterus that can be distorted by fibroid growth. This distortion can impact menstruation and pregnancy.
Pathophysiology and Development
Uterine fibroids develop through complex interactions between genetic factors, hormones, and growth factors. These benign tumors demonstrate a strong dependence on estrogen and progesterone for growth. Understanding their molecular basis helps in developing targeted treatments and predicting treatment responses.
Clinical Manifestations
Symptom Presentation
The clinical impact of fibroids varies significantly based on their size and location. Common symptoms include heavy menstrual bleeding leading to anemia, pelvic pressure, urinary frequency, and occasional pain. Some patients may remain asymptomatic despite large fibroids.
Impact on Reproduction
Fibroids can affect fertility through various mechanisms:
- Distortion of uterine cavity
- Interference with implantation
- Alteration of uterine blood flow
- Impact on sperm transport
Diagnostic Approaches
Imaging Studies
Modern imaging techniques provide detailed assessment:
- Transvaginal ultrasound as primary tool
- Sonohysterography for cavity evaluation
- MRI for precise mapping
- CT for specific complications
Laboratory Assessment
Key tests include:
- Complete blood count
- Iron studies
- Hormone levels
- Coagulation profile
Treatment Options
Medical Management
Various medical options available:
- GnRH agonists for temporary reduction
- Selective progesterone receptor modulators
- Hormonal contraceptives
- Antifibrinolytic agents
Surgical Approaches
Surgical options include:
- Myomectomy via various routes
- Hysterectomy when appropriate
- Minimally invasive techniques
- Uterine artery embolization
