Ultrasound ablation is a new technology for the treatment of fibroids, which is the thermal ablation of tumors by focusing ultrasound on the body through the outside of the body, and the whole treatment is carried out under image monitoring. Uterine fibroids gradually absorb, shrink and disappear naturally after inactivation. Advantages and disadvantages of ultrasonic ablation of fibroids: Advantages: ultrasonic ablation treatment preserves the uterus and reproductive function; no incision, no bleeding; no hospitalization and quick recovery; recurrence of fibroids can still be treated again. Traditional surgery, hysterectomy can eradicate fibroids, but leads to loss of the uterus; myomectomy can preserve the uterus, but it is invasive to the uterus, and hysterectomy is still required after recurrence. Cons: Because the uterus is preserved, there is a risk of recurrence of fibroids or new fibroids; 10-20% of patients with fibroids are not suitable for ultrasound ablation treatment. Clinical situation: Ultrasound ablation treatment of uterine fibroids has been developed over 10 years, from anesthesia to no anesthesia greatly reducing side effects, expanding the scope of application and being promoted in areas where it is available. Success rate: The success rate of cases screened by MRI is currently 97%. Procedure: After diagnostic imaging (MRI), the initial determination of suitability for ultrasound ablation treatment is made. Pre-treatment needs to go through a predetermined position, and the date of treatment is determined after routine liver and kidney function and gynecological routine examination; a simple dietary preparation before treatment, and an enema to remove residue and gas from the intestine is required on the day of catheterization treatment. The patient remains awake in a sedated analgesic state during treatment, which generally lasts within 2 hours. After treatment, the patient is observed for 2 hours and can leave the treatment room to go home or to rest in the ward.
