76
Evaluation of AUB

- Changes in general health
- Pt to keep record of bleeding patterns - differentiate abnormal & variation of normal
- Abdominal pain
- Dyspareunia
- Galactorrhea
- Hirsutism, acne
- Weight gain
- Petechiae, ecchymosis
- Pallor
77
Eval of AUB:

- Atrophic & inflammatory vulvar and vaginal lesions can be visualized
- Cervical polyps and invasive lesions
- Rectovaginal exam is especially important- palpate uterus
78

pelvic US, endometrial biopsy, hysteroscopy, D&C, consider CT or MRI of abdomen and pelvis
-**Refer to OB-GYN
79

- -and >___yo
40
80
EVALUATION OF AUB:

- Endometrial cells in a postmenopausal women abnormal on PAP
81
Other evaluation tools:
- Endometrial tissue biopsy
- Transvaginal ultrasound
- Hysteroscopy
82
Describe Hysteroscopy and why is it important in eval of pathology in the uterine cavity?
- Direct visualization of the endometrium via camera into endometrial cavity with immediate biopsy. Done as outpatient.
- ** Gold standard for evaluation of pathology in the uterine cavity**
83
PELVIC ULTRASOUND
- Has become an integral part of the gynecological pelvic exam
- Scan done transabdominally or transvaginally
- **Transvaginal U/S with empty bladder gives greater details of pelvic organs
- Transabdominal U/S performed with full bladder, enables a wider but less discriminative exam of pelvis
84
AUB – Endometrial Biopsy
- Use of a curette, cervical dilation not always needed
- Small samples of tissue removed from the endometrium
- Samples are looked at under a microscope to identify abnormal cells
- Tissue obtained sometimes may be inadequate for dx so hysteroscopy or D&C must be performed
85
D & C - Dilatation and Curettage (describe)
=a procedure to remove tissue from inside the uterus.
-Procedure used to dx and treat certain uterine conditions such as heavy bleeding or to clear the uterine lining after a miscarriage or abortion.
-Done under local anesthesia, almost always in an outpatient or ambulatory surgical setting.
86
Treatment of AUB:
| -primary goal=
- Determine underlying cause
- Resume regular shedding of the endometrium
- Regulation of uterine bleeding
- **Rule out cancer
87
Treatment of AUB:
| -Progesterone->
Progesterone agent – Depo injections or IUD may be helpful in some cases
88
Treatment of AUB:
| OCPs-->
- Suppresses the endometrium
| - Established regular predictable withdrawal cycle
89
Treatment of AUB:
| -surgical?
Endometrial ablation, surgical management, or hysterectomy
90

OCPs (combined estrogen and progesterone) have protective effect
