Study Notes
Abnormal Uterine Bleeding (AUB) Overview
- AUB defined as menstrual flow that deviates from normal volume, duration, regularity, or frequency.
- One-third of gynecologist outpatient visits are for AUB; it constitutes over 70% of gynecologic consultations in perimenopausal and postmenopausal women.
Classification of AUB
- A new classification system, PALM–COEIN, categorizes AUB into structural and nonstructural causes.
- Structural causes (PALM):
- Polyp (AUB-P)
- Adenomyosis (AUB-A)
- Leiomyoma (AUB-L)
- Malignancy & hyperplasia (AUB-M)
- Nonstructural causes (COEIN):
- Coagulopathy (AUB-C)
- Ovulatory dysfunction (AUB-O)
- Endometrial (AUB-E)
- Iatrogenic (AUB-I)
- Not yet classified (AUB-N)
Normal Menstrual Cycle Parameters
- Normal menstrual flow typically lasts 5 days.
- Menstrual cycles range from 21 to 35 days.
Evaluation of AUB
- Comprehensive evaluation includes medical history, physical examination, and diagnostic tests.
- Key elements of medical history:
- Patterns and severity of menstrual bleeding.
- Pain associated with bleeding.
- Family history of AUB or bleeding disorders.
- Conditions like von Willebrand disease and PCOS must be considered.
Diagnostic Procedures
- Initial screening for underlying bleeding disorders is critical for women with heavy menstrual bleeding.
- Imaging studies:
- Transvaginal ultrasound is often the first line for imaging.
- Hysteroscopy and sonohysterography may be necessary for further evaluation.
Management Guidelines
- Risk factors for endometrial hyperplasia or malignancy dictate the necessity of endometrial biopsy.
- Women at higher risk should undergo appropriate imaging assessments (e.g., MRI if required).
- Management tailored based on the classification of AUB and individual patient factors.
Pathophysiology of AUB
- Common causes of AUB include:
- Endometrial polyps (AUB-P)
- Adenomyosis (AUB-A)
- Uterine leiomyomas (AUB-L)
- Endometrial hyperplasia or carcinoma (AUB-M)
- Ovulatory dysfunction (AUB-O) linked to hormonal imbalances, often due to endocrine disorders.
Clinical Recommendations
- Differentiating between structural and nonstructural causes is essential for appropriate treatment.
- Continued research and understanding of AUB patterns are crucial for advancing clinical practices.
