Sound passes through the skin
The device sends ultrasound from outside the body, so treatment does not require a skin incision. The hospital checks whether the beam path is suitable.
HIFU Treatment Guide
Learn how focused ultrasound treatment for fibroids works, compare adenomyosis treatment options, and prepare questions for a specialist.
High-intensity focused ultrasound (HIFU) directs sound energy from outside the body toward selected tissue. A specialist reviews imaging to decide whether a fibroid or adenomyosis lesion can be treated this way.

Focused energy heats selected tissue. The clinical team adjusts treatment using its imaging and monitoring protocol.
Planning aims to limit exposure of surrounding organs, but complications can still occur. Ask how risks are managed for your anatomy.
Treated tissue may change or shrink over time. Follow-up imaging and symptoms help the specialist assess the result.
Medicines and hormonal treatments may help manage bleeding or pain from fibroids or adenomyosis. Benefits and side effects vary by treatment and person. If symptoms remain difficult to manage, ask a specialist about uterus-sparing procedures and surgical options.
Your specialist will review your symptoms and imaging before discussing whether HIFU is an option.
Ask your specialist how your diagnosis affects the treatment choices and expected symptom relief.
| Question | HIFU | Myomectomy | Hysterectomy |
|---|---|---|---|
| Approach | High-Intensity Focused Ultrasound (HIFU) | Surgical fibroid removal | Surgical uterus removal |
| Uterus | Retained | Retained | Removed |
| Future pregnancy | Effects remain uncertain | Discuss risks and timing | Cannot carry a pregnancy |
| Incision / scarring | No skin incision | Depends on hysteroscopic, laparoscopic or open approach | Depends on vaginal, laparoscopic or open approach |
| Anaesthesia | Hospital-specific sedation plan | Depends on the surgical and anaesthesia plan | Depends on the surgical and anaesthesia plan |
| Hospital stay | May be outpatient; hospital decides | Often inpatient; depends on surgical approach | Usually inpatient; depends on surgical approach |
| Return to work | Ask about your own recovery plan | Recovery varies with surgical approach | Recovery varies with surgical approach |
| Conception waiting period | Individual specialist advice; evidence remains uncertain | Depends on surgery and healing; ask your specialist | Pregnancy not possible |
Ask about non-surgical options too. The right choice depends on your symptoms, diagnosis and priorities.
Recent MRI or ultrasound and any additional tests requested by the hospital.
Previous procedures, medicines and any other health conditions.
Bleeding, pain and how symptoms affect your daily life.
Pregnancy plans, treatment preferences and recovery needs.
Plan time for hospital assessment, treatment if suitable, observation and a discharge review. Your hospital will confirm the schedule before you travel.
The procedure and its duration depend on your imaging, treatment plan and hospital protocol.
The team checks your condition after treatment and decides when you can safely leave the hospital.
Ask your hospital when you can return to daily activity, work and exercise; recovery varies by person.
Ask which symptom reviews and imaging checks you need after returning home, especially if you plan pregnancy.
Fibroids: HIFU may suit intramural, subserosal and selected submucosal fibroids, whether single or multiple, when the lesion is at least 2 cm and has a safe ultrasound path. It is worth considering if heavy or prolonged periods, anaemia, pelvic pressure, urinary frequency or constipation affect you, or if you want to preserve your uterus or have fibroids after a previous myomectomy.
Adenomyosis: Both focal adenomyoma and diffuse adenomyosis can be assessed for HIFU, with relief of painful or heavy periods and chronic pelvic pain as the goal. It may also be an option if medication is hard to tolerate or a Mirena device has been expelled. Your doctor can use your imaging and symptoms to advise whether HIFU suits you.
HIFU is not suitable during pregnancy, with an active pelvic or genital infection, or when bowel or bone blocks a safe ultrasound path. A lesion suspicious for cancer needs investigation first.
Severe bleeding disorders, serious liver or kidney disease, inability to stay in the required position or communicate during treatment, and some implanted devices can also rule it out or require preparation. Tell the team about any IUD, pacemaker or breastfeeding. Your doctor can confirm which of these applies to you.
Fibroids: HIFU can ease heavy or prolonged periods and pressure symptoms such as pelvic fullness, lower back discomfort, urinary frequency and constipation. Anemia may improve as bleeding falls, though it may also need separate treatment.
Adenomyosis: HIFU can relieve painful or heavy periods, chronic pelvic pain and pain during sex. Some patients also see a reduction in uterine size. Your doctor can tell you which symptoms are most likely to improve in your case.
Fibroids (from better to more challenging candidates): Intramural and broad-based subserosal fibroids often respond well. With multiple fibroids, treatment can focus first on the larger lesions causing symptoms. Fibroids that appear after laparoscopic or open myomectomy are also worth assessing, since HIFU does not require another abdominal operation; the scar and ultrasound path still need checking. For 5–10 cm fibroids, GnRH-a may be used first to reduce size; those over 10 cm may be assessed for treatment in stages. Small, thin-stalked submucosal fibroids under 3 cm are often better treated by hysteroscopy.
Adenomyosis: A well-defined focal adenomyoma is easier to target; for diffuse adenomyosis, the goal is symptom relief rather than complete removal. Treatment may reduce uterine size and may help with Mirena retention. Cellular, T2-bright or very vascular fibroids are more challenging and may need medication beforehand. Your doctor can assess the likely response from your imaging.
HIFU treats the fibroid without an abdominal incision and preserves the uterus. Laparoscopic or open myomectomy removes the fibroid and also preserves the uterus, but new fibroids can develop and symptoms can return after either operation. HIFU can also need further treatment if symptoms persist or return.
The practical differences are whether the fibroid is ablated or removed, whether an incision is needed, and the recovery and risks of each approach. Hysterectomy removes the uterus and therefore the possibility of future uterine fibroids, but it is a different decision from choosing between HIFU and myomectomy. Your doctor can compare these options for your lesions and priorities.
Published guidance can help you prepare questions for a specialist. It does not determine whether HIFU is right for you.
Chinese expert consensuses discuss fibroids, adenomyosis and focused ultrasound practice. NICE published guidance for symptomatic fibroids in 2019 (IPG657, now HTG523); it says evidence on efficacy is limited in quality and calls for special arrangements for governance, consent and audit or research.
Symptoms may persist or return, and further treatment may be needed. Possible complications include pain, skin burns, bleeding or discharge and, rarely, injury to nearby organs. Effects on fertility and future pregnancy remain uncertain.
