What
High-intensity focused ultrasound (HIFU) focuses sound energy on adenomyotic lesions under ultrasound or magnetic resonance guidance, causing controlled thermal coagulation. It usually involves completing imaging localization and planning first, then delivering energy in multiple fractions after sedation and analgesia, and monitoring the landing point and surrounding temperature with real-time imaging, adjusting parameters as necessary to protect adjacent structures. Postoperative observation includes pain and body temperature, with subsequent imaging to evaluate lesion changes. The above is general health information, not medical advice; specific information is subject to specialist assessment and hospital protocols.
How
- Anesthetize and complete localization and planning using ultrasound.
- Deliver energy in multiple fractions to thermally coagulate the lesion.
- Real-time imaging monitors and adjusts to protect adjacent structures.
- Postoperative observation of pain, body temperature, and imaging evaluation.
Recovery
Mild lower abdominal pain or a small amount of vaginal discharge is common after surgery. Medical staff will monitor body temperature, pain, and skin condition. Gradually resume daily activities within a few days, avoid strenuous exercise and tub baths, and follow medical advice for ultrasound or MRI re-examination to evaluate lesion changes. Air travel can be arranged after doctor's evaluation; bring discharge information for customs clearance and follow-up medical care.
- Postoperative monitoring of body temperature, pain, and skin condition.
- Resume daily activities within a few days, avoiding strenuous exercise.
- Follow medical advice for re-examination and arrange air travel if needed.
FAQ
Will it leave a scar?
Generally, no incision is required. The skin may develop temporary erythema or heat sensation, which usually resolves over time.
Will it affect fertility?
HIFU aims to preserve the uterus, but there is no guarantee of fertility outcomes. Uterine conditions and past medical history should be assessed before surgery, and plans should be discussed with the doctor.
Is HIFU guided by ultrasound or MRI?
Both modes are common. The hospital will choose based on equipment conditions and lesion characteristics, with the goal of ensuring clear imaging and accurate energy localization.
What if symptoms do not improve or recur?
Depending on the follow-up results, continuing follow-up, combined medication, re-ablation, or switching to other regimens can be considered, as comprehensively assessed by the team.
Is general anesthesia required? Will it hurt?
Mostly sedation and analgesia combined with local cooling and monitoring are used. Individual pain perception varies greatly; the anesthesia method is determined by the anesthesiology evaluation.
What information should I bring for the consultation?
Recent ultrasound or MRI, blood tests, previous treatment and surgery records, allergy and medication lists are helpful for rapid assessment.
What changes will occur in menstruation after surgery?
Menstrual flow and pain may gradually change. The specific reaction varies from person to person; follow-up imaging and symptoms are required as directed by the doctor.
Can it still be done if there is metal/intrauterine device in the body?
A specialist needs to assess the imaging compatibility and safety before deciding whether it is applicable or needs to be handled first.
