High-Intensity Focused Ultrasound (HIFU) is a modern medical technology used to treat uterine fibroids without open surgery. This method is classified as non-invasive because it does not require incisions, stitches, or conventional surgical procedures. HIFU is one of the latest innovations in obstetrics and gynecology, offering a more comfortable treatment alternative with lower bleeding risk and a relatively faster recovery period compared to surgery.
Today, HIFU technology is available at RS Mandaya Royal Puri as a non-surgical option for fibroid treatment. Its implementation is supported by obstetricians and gynecologists who have undergone intensive HIFU training in China, ensuring the procedure meets international standards while prioritizing patient safety and comfort.

How HIFU Technology Works to Treat Fibroids Without Surgery
Below is how HIFU technology works to treat fibroids without surgery:
-
Highly precise focused ultrasound waves: During a HIFU procedure, high-intensity ultrasound waves are precisely directed at a small focal point within the fibroid tissue. The accuracy reaches the millimeter scale, ensuring that the energy is concentrated only on the targeted area. With the assistance of medical imaging, doctors can ensure that surrounding healthy tissue remains safe and unaffected.
-
Energy converts into high heat at the target point: When the ultrasound waves converge at the designated point, the energy transforms into heat with temperatures ranging from approximately 60–90°C. This heat is generated only at the focal area, not throughout the entire organ, making the effect controlled and directly targeted at the fibroid tissue.
-
Heat causes fibroid cells to be damaged and destroyed: The high temperature causes proteins within the fibroid cells to coagulate. As a result, the fibroid cells experience permanent damage and eventually die (necrosis). This process occurs without any incision or open surgery, as the entire treatment is performed externally.
-
Damaged tissue is naturally absorbed by the body: After the fibroid cells die, the body gradually absorbs the damaged tissue through natural biological mechanisms. This shrinkage process is not immediate but occurs progressively over several weeks to months, generally around 90 days. Over time, the fibroid decreases in size without the need for conventional surgical intervention.
Advantages of HIFU for Fibroid Treatment
HIFU technology offers numerous benefits as a non-surgical solution for fibroid management. Compared to conventional surgical procedures, this method provides greater comfort, lower risk, and a shorter recovery time. Key benefits include:
- No surgical incisions required: The HIFU procedure is performed without open surgery, meaning there are no incisions or stitches on the body.
- Milder pain levels: As a non-invasive procedure, HIFU generally causes significantly less discomfort compared to conventional surgery.
- No radiation exposure: HIFU uses ultrasound waves rather than radiation, making it safer in terms of radiation exposure.
- Uterus preservation: In many cases, HIFU allows fibroids to be treated without removing the uterus, helping preserve reproductive function.
- Very low bleeding risk: Since there are no incisions or open surgical procedures, the risk of bleeding during treatment is significantly reduced.
- Shorter recovery period: Patients typically do not require prolonged hospitalization and can recover faster compared to traditional surgery.
- Faster return to daily activities: With a relatively quick recovery, patients can usually resume normal daily activities sooner.
