Incidence rate of benign uterine diseases
Fibroids
Fibroids are the most common benign tumors of the female genital tract, with a symptomatic occurrence rate of 20%-40% in reproductive-age women. Clinical symptoms: Abnormal uterine bleeding, secondary anemia, pelvic compression symptoms and pain, reproductive dysfunction, etc.
Adenomyosis
Most often diagnosed in middle-aged women and women who have had children. With the delayed childbearing age, the incidence rate among unfertile women has increased in recent years Clinical symptoms: Heavy or prolonged menstrual bleeding, severe cramping or sharp, knife like pelvic pain during menstruation (dysmenorrhea), chronic pelvic pain, etc.
Principle of microwave ablation
With the guidance of imaging system, microwave ablation antenna is directly punctured into the tumor. Polar molecules inside the tissue move rapidly within microwave electromagnetic field, generating heat through mutual friction. When the intra-tumor temperature reaches 60°C, the cancer cell proteins will be denatured and result in irreversible necrosis. This procedure will have very small effect on other tissues. It will help improve patient’s immunity and inhibit the proliferation of cancer cells.
Indications - Fibroids
- Clinically diagnosed fibroids. FIG grade 0-6
- Accompanied by abdominal pain, menorrhagia, secondary anemia, compression and other symptoms
- Patient has no perimenopausal signs
Indications Adenomyosis
- Clinically diagnosed adenomyosis (The width of uterine junction >13 mm);
- Accompanied by progressive dysmenorrhea or menorrhagia, anemia or compression symptoms:
- Patients who have not given birth or have given birth but have strong desire to keep the uterus. Has no perimenopausal signs, and there is a safe puncture path through the abdominal wall.
- Lesion thickness > 30mm: dysmenorrhea symptom score > 4 or hemoglobin values 10g, dysmenorrhea or anemia symptoms continued for more than 1 year and continued to worsen; patient refuses hysterectomy or other invasive treatment, and voluntarily chooses percutaneous microwave ablation.
Comparison of different treatment methods
|
|
|
|---|---|
|
Laparoscopic or hysteroscopic removal of lesions
|
Suitable for fibroids, but not so effective on adenomyosis. especially diffuse adenomyosis. Pregnancy rate after operation is low
|
|
Hysterectomy
|
Radical treatment method, but side effects are serious, affects ovarian function, not suitable for young women who have not had children,
|
|
Chemical ablation
|
Suitable for lesions smaller than 3cm.
|
|
Medication
|
Can temporarily improve symptoms but can't make the fibroids go away: (Women with pressure symptoms caused by large fibroids won't benefit from any medicines currently available) Side effects are serious, many adverse reactions, relapse after stopping medication
|
|
HIFU
|
Application scope is limited, focus area is small, needs to be repeated for many times; it's more effective for smaller lesions with thinner abdominal wall and less blood supply operation is time-consuming.
|
|
Uterine artery embolization
|
Can lead to posprocedural pain, postembolization syndrome (complete amenonbea, subclinical damage of the ovarian function), and risk of infection Contraindicated in woman desiring future pregnancies;
Radiation exposure; High risk of re-intervention rate.

Advantages of microwave ablation in the treatment of fibroids and adenomyosis
- Preserve uterus, no damage to pelvic structure. Lesions wil be inactivated and significantly reduced in size after ablation. which can improve or eliminate the clinical symptoms (such as dysmenorrhea, large menstrual volume, anemia, etc.).
- Has no effect on ovarian function, menstrual cycle will be normal after ablation.
- No surgery required, can be treated through percutaneous or transvaginal approach,
- Simple operation, short ablation time, less trauma, no scar,safe and effective.
