Grows deep inside the muscle wall of the uterus. It enlarges the uterus and the area of the uterine lining, which makes periods heavier.
Grows just under the outer layer covering the uterus. It can hang down and form a stalk.
Causes many complications. Even a small one can cause bleeding. It has a higher risk of sarcomatous change, is prone to infection, pus formation and tissue death, and does not respond well to radiation.

HIFU keeps the uterus instead of removing it and uses high-intensity ultrasound heat to destroy the tumor. Unlike open or laparoscopic surgery, you can return to daily life quickly after treatment.
It is popular with unmarried women diagnosed with benign fibroids, women planning pregnancy, and working women.
The best treatment for humansMapping the path of the ultrasound energy for safe treatment. The key to HIFU is delivering focused ultrasound energy precisely to the lesion. Precise image analysis shows both where the lesion is and the path the ultrasound energy will take.
Artificial Intelligence - Software SystemThe body is always moving. Accurate treatment requires tracking the lesion's position in real time as it moves. This is what makes treatment at Aegis Roen OB-GYN safer.
Precise PositioningWe set the exact entry path of the high-intensity focused ultrasound energy to match the patient's body shape and the position and size of the uterus and tumor.
High Intensity Focused Ultrasoundhighly efficient, high-intensity ultrasound energy forms a precise focus for a powerful treatment effect

HIFU is an advanced treatment that focuses ultrasound from outside the body onto one point, like a magnifying glass, raising the temperature at the target to destroy fibroid cells. Unlike myomectomy or hysterectomy, its big advantages are no general anesthesia and no abdominal incision, and you can return to daily life soon after a 2–3 day hospital stay.
To make HIFU safer and more effective, the shape and location of the fibroid must be identified precisely with ultrasound and detailed MRI. This is what allows an accurate diagnosis and a good result.
Expertise in difficult cases
Dr. Jae-Seong Lee, with more than 2,000
successful fibroid treatments
HIFU tailored to each typeHigh-intensity focused ultrasound, harmless to the body,
destroys the fibroid tissue
Stabilizing abnormal blood flow
HIFU is performed after stabilizing
abnormal blood flow in the fibroid
Surgery that removes the whole uterus because the fibroid is large
Surgery that removes the fibroid with instruments through small cuts instead of a large abdominal incision
Surgery that removes the fibroid itself
MRI before treatment to check whether a lesion could become malignant and to look for hidden malignant lesions
Ultrasound and MRI monitoring during treatment
Results review and objective evaluation after HIFU
MRI is used to analyze the fibroid (location, number, size, shape, etc.), its blood supply, nearby organs and structures, and a clear path for the ultrasound. Detailed ultrasound then analyzes the number of fibroids to treat, the number of treatment slices, the volume of each slice, the treatment margin and the relationship between the fibroid and nearby organs.
Based on the MRI before treatment, we precisely identify the location, size and shape
of tumors such as fibroids or adenomyosis
and plan the treatment, including the ultrasound energy level
and entry path
Following the treatment plan, HIFU is guided by fused ultrasound/MRI
images and real-time ultrasound

Before treatment, we check whether a lesion could become malignant and look for hidden malignant lesions.
After treatment, we explain the results and review them objectively
and make an aftercare plan.
We combine ultrasound and MRI images
to monitor your progress after treatment.
Based on the aftercare plan, we check at set intervals (from the day after treatment, then monthly, quarterly, every six months and yearly) how much the treated lesion has shrunk and whether there is a risk of recurrence.
From before HIFU until your regular check-ups after discharge, we take care of every detail.
A dedicated coordinator at the clinic looks after
your follow-up visits and recovery.
