Adenomyosis at a Glance

• What it is — Adenomyosis is a benign condition in which endometrium-like tissue grows into the uterine muscle, potentially causing heavy bleeding, severe cramps, pelvic pain, pressure, anemia, and an enlarged tender uterus.
• Diagnosis first — Transvaginal ultrasound is usually the first test; pelvic MRI can clarify uncertain cases, distinguish focal from diffuse disease, identify fibroids or endometriosis, and determine eligibility for uterus-preserving treatment.
• Treatment is individualized — Options range from pain medicines, hormonal therapy, and an LNG-IUS to HIFU, uterine artery embolization, adenomyomectomy, or hysterectomy, depending on symptoms, anatomy, anemia, and pregnancy goals.
• Fertility is a key limit — HIFU, UAE, thermal ablation, and adenomyomectomy retain the uterus but do not guarantee future fertility; reproductive outcomes remain uncertain and require individualized counseling before treatment.
• Definitive option — Hysterectomy permanently removes uterine adenomyosis and stops menstrual bleeding, but it also permanently ends the ability to carry a pregnancy; open abdominal recovery commonly takes about 6–8 weeks.
• Korea travel timing — Allow 2–4 business days for diagnostic review, at least 5–7 days for HIFU or UAE, and at least 10–14 days after hysterectomy discharge before a long-haul flight, with surgeon clearance.
• Korea HIFU distinction — A Korean retrospective study of 1,372 ultrasound-guided HIFU patients reported a mean 61.4% adenomyosis-volume reduction at 12 months, but this center-level retrospective result is not a guaranteed individual outcome.

What Is Adenomyosis?

Adenomyosis is a benign condition in which tissue similar to the uterine lining grows within the muscle of the uterus. Treatment aims to reduce heavy bleeding, severe cramps, pelvic pain, pressure, and anemia while considering uterine preservation and future pregnancy goals. Care is non-surgical, minimally invasive, or surgical depending on the chosen treatment.

Who Is a Good Candidate for Adenomyosis?

• Symptomatic patients — Good candidates have heavy or prolonged periods, severe menstrual cramps, chronic pelvic pain or pressure, anemia, or an enlarged tender uterus that is affecting daily life.
• Patients seeking diagnostic clarity — A gynecology review is useful when symptoms could also reflect fibroids, endometriosis, ovarian disease, or another cause of abnormal bleeding.
• Those considering uterine preservation — Patients who want to retain the uterus can discuss medication, an LNG-IUS, HIFU, uterine artery embolization (UAE), thermal ablation, or selected adenomyomectomy after imaging-based assessment.
• Patients finished with childbearing — Hysterectomy is an option for severe or persistent symptoms when carrying a future pregnancy is no longer a goal.

Adenomyosis occurs when endometrium-like glands and stroma grow within the uterine muscle, or myometrium. Treatment is not determined by age alone: symptom burden, anemia, focal versus diffuse disease, uterine anatomy, coexisting fibroids or endometriosis, and pregnancy plans all matter. Pregnancy needs individualized obstetric care; UAE, thermal ablation, adenomyomectomy, and hysterectomy are not routine treatments during an ongoing pregnancy. Seek urgent local assessment rather than elective overseas care for very heavy bleeding with fainting, chest pain, shortness of breath, fever, a positive pregnancy test, severe new pelvic pain, or concern for ectopic pregnancy, infection, or cancer.

How Is Adenomyosis Performed?

Adenomyosis management is a decision pathway, not one operation. Clinical guidance supports individualized medical, interventional, and surgical choices after discussing symptoms, uterine preservation, and fertility goals.

• Symptom-directed medication — NSAIDs can reduce period pain when medically safe. Hormonal options include combined hormonal contraception, progestins such as dienogest, and selected gonadotropin-releasing hormone (GnRH) analogue regimens such as leuprolide. These treatments do not remove adenomyosis and require review of clotting history, migraine with aura, hypertension, liver disease, osteoporosis risk, hormone-sensitive cancer history, and drug interactions.
• LNG-IUS — A levonorgestrel-releasing intrauterine system, often known by the brand Mirena, delivers progestin in the uterus and is commonly used to reduce heavy bleeding and pain. It is unsuitable with untreated abnormal bleeding, current pelvic infection, major uterine-cavity distortion, or a contraindication to the hormone. Read more about Mirena IUD placement.
• Focused ultrasound and thermal ablation — HIFU uses focused acoustic energy to heat targeted adenomyosis tissue without an incision. Ultrasound-guided and MR-guided focused ultrasound use different planning and treatment-verification approaches; selected radiofrequency and microwave techniques are also used. MRI or detailed ultrasound must confirm a safe path clear of bowel, bladder, sacral nerves, skin, and problematic scars or adhesions.
• Uterine artery embolization — An interventional radiologist places a catheter in an artery and injects embolic particles to reduce uterine blood flow. UAE retains the uterus but can cause substantial post-procedure pain, nausea, fever, and fatigue, and it is not fertility-neutral.
• Adenomyomectomy — This surgery removes focal adenomyosis while retaining the uterus. It is technically demanding and best suited to selected, well-defined adenomyomas; diffuse disease often has no clear surgical boundary. A reconstructed uterine wall has important implications for a future pregnancy.
• Hysterectomy — Removing the uterus is the definitive treatment for uterine adenomyosis and permanently ends menstrual bleeding and the ability to carry a pregnancy. Vaginal, laparoscopic/robotic, and abdominal routes depend on uterine size, anatomy, previous operations, and coexisting disease. It does not treat endometriosis outside the uterus.

Why Visit Korea for Adenomyosis?

Korea can be a practical setting for an imaging-led adenomyosis review when a center can coordinate gynecology, pelvic imaging, fertility medicine, interventional radiology, and surgery. It is not a reason to rush into an irreversible treatment. Ask each institution for a written plan for diagnosis, complication care, and follow-up after return home.

• International-care infrastructure — Korea’s Medical Korea program provides an established framework for international patients. Confirm that the specific hospital is authorized to treat international patients and can provide qualified interpretation and English records.
• HIFU experience to examine critically — A Korean retrospective study reported outcomes for 1,372 adenomyosis patients treated with ultrasound-guided HIFU between 2010 and 2025, including a mean 61.4% adenomyosis volume reduction at 12 months. This is center-level retrospective evidence, not an independently audited multicenter outcome guarantee for an individual patient.
• Imaging-based eligibility — Selected centers can review transvaginal ultrasound and pelvic MRI before deciding whether HIFU, UAE, adenomyomectomy, or surgery is anatomically appropriate. This matters because focal and diffuse disease, uterine position, lesion perfusion, abdominal-wall thickness, scars, adhesions, and bowel position affect treatment selection.
• Questions worth asking — Request the exact HIFU device and guidance method, MRI eligibility criteria, bowel-safety protocol, treatment-completeness assessment, complication definitions, reintervention rate, and named overseas contact. Current evidence does not establish a universally accepted treatment sequence, especially for fertility-directed care.

Key Information for International Patients

• Minimum stay for diagnosis — Allow about 2–4 business days for consultation, transvaginal ultrasound, possible MRI, blood tests, and a results discussion. An LNG-IUS can sometimes be placed during this period once eligibility is confirmed.
• Stay for HIFU or UAE — Plan at least 5–7 days for imaging confirmation, treatment, immediate recovery, and an early review. HIFU response is assessed over later menstrual cycles and repeat treatment can be necessary; UAE commonly requires overnight observation for pain control and monitoring.
• Stay for hysterectomy — Remain in Korea at least 10–14 days after discharge before considering a long-haul flight, and fly only with explicit surgeon clearance. Complete recovery after open abdominal hysterectomy often takes about 6–8 weeks; minimally invasive routes generally recover faster.
• Flight restrictions — Do not fly while needing opioid-level pain control or with uncontrolled bleeding, fever, symptoms of anemia, a painful swollen leg, chest pain, shortness of breath, or suspected infection.
• Itinerary impact — Keep the days after UAE or surgery free of sightseeing commitments. Cramping and spotting for several days can follow LNG-IUS placement; HIFU can be outpatient or short-stay, but delayed pain, skin injury, and bowel symptoms require prompt assessment.
• Remote follow-up — Arrange a clinician at home before travel. Leave with DICOM imaging files, imaging reports, procedure and anesthesia records where applicable, discharge summary, pathology report if tissue was removed, and an English medication list with generic names, doses, and duration.

Travel note: A medical-trip goal should be a documented, imaging-based treatment plan—not a rushed irreversible procedure. Confirm a named after-hours contact route before paying for non-refundable flights.

• Adenomyosis treatment:
  • HIFU uses focused ultrasound to ablate targeted tissue without invasive surgery.
  • For adenomyosis, the clinic states that HIFU aims to reduce lesion size and alleviate pain and heavy menstrual bleeding.
• Other gynecologic options:
  • Laparoscopic surgery is available for conditions including endometriosis and ovarian cysts, using small incisions and camera-guided instruments.
  • Da Vinci robotic surgery is offered for complex gynecologic procedures such as hysterectomy or myomectomy.
  • Hysteroscopic surgery can be used to diagnose and treat intrauterine conditions, including polyps and fibroids.
• Related condition services:
  • The clinic offers sclerotherapy services for ovarian cysts and endometriosis as non-surgical treatment options.
  • Care is described as one-stop diagnosis and treatment for uterine and ovarian conditions, with treatment methods personalized to your situation.

Adenomyosis From Start to Finish

1. Send records before travel — Provide prior ultrasound and MRI reports, DICOM image files where available, operative and pathology reports, menstrual calendar, fertility history, current medicines, CBC and ferritin results, and details of prior pelvic surgery.
2. Complete a virtual or English-language consultation — Discuss bleeding, pain, anemia, pregnancy plans, prior hormonal treatment, and whether preserving the uterus or future fertility is a priority. The team should explain whether an in-person examination and imaging review are required before any treatment decision.
3. Confirm the diagnosis — A gynecologist takes a focused history and performs a pelvic examination when appropriate. Transvaginal ultrasound is generally first-line imaging; pelvic MRI helps clarify equivocal cases, distinguish focal adenomyoma from diffuse disease, identify coexisting pathology, and plan uterus-preserving intervention.
4. Assess treatment readiness — Pregnancy testing, CBC and iron studies, and other tests are selected according to symptoms and method. UAE needs kidney-function, contrast-allergy, infection, and coagulation assessment; sedation or surgery requires anesthesia evaluation.
5. Choose the treatment pathway — Review medication, LNG-IUS, HIFU, UAE, adenomyomectomy, and hysterectomy against symptom severity, anatomy, anemia, coexisting endometriosis or fibroids, and fertility plans. A small 2026 randomized trial compared UAE with dienogest over six months, but it does not establish the best sequence among all available treatments.
6. Undertake the planned treatment — LNG-IUS placement is usually an outpatient visit. HIFU uses focused heat without an incision and requires imaging-guided planning; UAE is catheter-based and often involves overnight observation; adenomyomectomy and hysterectomy require an operating-room procedure and anesthesia.
7. Receive early recovery review — The team checks bleeding, pain control, fever, urinary function, mobility, wound status after surgery, and any HIFU skin or abdominal symptoms. Obtain written activity limits, medication instructions, flight clearance criteria, and emergency contact details.
8. Continue follow-up after return home — Track bleeding, pain, temperature, and medication effects. Share records with the home clinician, and arrange the treating team’s remote review at the interval appropriate to the treatment and fertility plan.

Alternatives to Adenomyosis

The main tradeoff is between preserving the uterus and choosing the treatment most likely to give definitive symptom control. Non-surgical options can reduce bleeding and pain without major surgery but often require ongoing treatment, have anatomy limits, or carry uncertain future-pregnancy outcomes. Hysterectomy is definitive for uterine adenomyosis but permanently removes the ability to carry a pregnancy.

Medication or LNG-IUS

• Best suited to — Patients who want symptom control, wish to avoid an invasive procedure, or need time to clarify fertility plans.
• Tradeoff — NSAIDs address pain rather than the disease itself; hormonal treatment can cause side effects, has medical contraindications, and does not suit every patient trying to conceive now.
• Related option — See Mirena IUD treatment for the LNG-IUS pathway.

HIFU or Other Thermal Ablation

• Best suited to — Carefully selected patients with a safe acoustic or thermal-treatment path on imaging who want a non-incisional uterus-preserving option.
• Tradeoff — Eligibility is anatomy-dependent, treatment completeness differs by lesion and device protocol, and long-term reproductive outcomes remain uncertain.

Uterine Artery Embolization

• Best suited to — Patients seeking uterine preservation for bleeding, pain, or bulk symptoms who accept catheter treatment and its recovery demands.
• Tradeoff — Post-embolization pain can be substantial, and fertility and ovarian effects require careful individualized counseling.

Adenomyomectomy

• Best suited to — Highly selected patients with a focal adenomyoma, refractory symptoms, and a strong reason to retain the uterus.
• Tradeoff — Diffuse adenomyosis is difficult to excise completely. Future pregnancy needs high-risk obstetric input because of the reconstructed uterine wall.

Hysterectomy

• Best suited to — Patients with severe or refractory symptoms who do not wish to carry a future pregnancy.
• Tradeoff — It is definitive for adenomyosis in the uterus but is major surgery and does not remove endometriosis outside the uterus. Explore hysterectomy separately for route and recovery considerations.

How Can I Prepare for Adenomyosis?

• Send complete records early — Upload imaging reports and DICOM files, prior surgical and pathology reports, menstrual calendar, fertility history, CBC/ferritin results, and current medication list before travel.
• Disclose medicines and supplements — List prescription drugs, over-the-counter pain medicines, anticoagulants, antiplatelet drugs, herbal products, vitamins, injectable weight-loss medicines, allergies, implants, and prior contrast reactions. Do not independently stop anticoagulants or antiplatelet medicines; the prescribing clinician and procedural team must provide a written plan.
• Report relevant health history — Tell the team about pregnancy possibility, hormone-sensitive cancer, migraine with aura, VTE history, hypertension, kidney or liver disease, diabetes, osteoporosis risk, active infection, smoking, and prior pelvic surgery or adhesions.
• Correct anemia before elective invasive care — Heavy menstrual bleeding can cause iron deficiency and anemia. Complete CBC and iron assessment, and follow the clinician’s plan for iron replacement or further treatment before HIFU, UAE, or surgery.
• Follow anesthesia instructions exactly — Fasting, bowel preparation, medication holds, antibiotics, hair removal, and skin preparation vary by procedure, device, sedation plan, and individual risk. Obtain these instructions in writing rather than relying on a standard online schedule.
• Plan recovery logistics — Book accommodation near the treating facility, organize an adult companion for UAE or surgery when requested, avoid alcohol and smoking according to the surgical team’s timeline, and keep flights flexible.

Travel note: Arrange local gynecology or primary-care follow-up before departure, particularly after UAE, HIFU, adenomyomectomy, or hysterectomy.

Confirm every clinic-specific requirement with the treating doctor; individualized instructions take precedence over general guidance.

Aftercare Advice

Treat severe bleeding, fever, escalating pain, and breathing or leg symptoms as urgent problems—not routine recovery.

• Track symptoms — Record bleeding, clots, temperature, pelvic or abdominal pain, nausea, bowel function, and medication reactions. HIFU treatment response is usually reviewed across subsequent menstrual cycles rather than immediately.
• Use pain medicines correctly — Take analgesics only as prescribed. Maintain hydration and prevent constipation, especially while using opioid pain medicine; contact the clinic for persistent vomiting or pain that is not controlled by the prescribed plan.
• Walk after UAE or surgery — Walk regularly as cleared to reduce venous-thromboembolism risk. Avoid strenuous exercise, heavy lifting, and long unsupervised excursions until the treating team clears them.
• Protect surgical healing — Keep incisions clean and dry according to the discharge instructions. After hysterectomy, use pads rather than tampons and avoid douching, intercourse, and all vaginal insertion for about 6 weeks unless the surgeon confirms earlier healing.
• Know warning signs — Seek same-day assessment for rapidly soaking pads or large clots, fainting, fever or chills, foul-smelling discharge, inability to urinate, worsening pelvic or abdominal pain, wound separation or pus, painful leg swelling, chest pain, or shortness of breath. After HIFU or UAE, urgent review is also needed for skin blistering, severe abdominal distension, fever, or bowel symptoms.
• Complete scheduled follow-up — Attend the early review before departure and remote follow-up after return home. Share the discharge summary and imaging with the clinician managing care at home.

Follow the treating doctor’s instructions over this general guidance, and contact the clinic promptly when anything appears wrong.
