HIFU For Uterine Fibroids

7 May 2019

What are Uterine Fibroids?

Uterine fibroids are the most common benign tumours in women of reproductive age. They grow along or within walls of the uterus, and are found in approximately 20% – 50% of women.

Also known as leiomyomas, it is important to note that your chances of developing a cancerous growth do not increase because you have uterine fibroids, nor does having them increase your chances of getting other uterine cancers.

In most cases, the symptoms of fibroids are rarely felt, except for an estimated 25 – 30% of women who experience negative symptoms. Fibroids are commonly discovered during pelvic examinations or ultrasounds.

What is HIFU for Uterine Fibroids?

High Intensity Focused Ultrasound (HIFU) is a new technology applied to the treatment of uterine fibroids.

HIFU focuses high energy ultrasound waves to generate localised heat energy at temperatures above 55°C to achieve cell death (coagulation necrosis) in uterine fibroids. Preserving the uterus, it is a non-invasive and organ-sparing procedure.

Conventionally, uterine fibroids are treated through surgeries such as hysterectomy or myomectomy, which sometimes require weeks of recovery. HIFU on the other hand, requires a much shorter downtime where patients can possibly return to work and daily living the very next day.

Depending on the location and size of your fibroid, HIFU treatment is a therapeutic option that has good potential in women of childbearing age who plan to have children.

Advantages of HIFU

  • Non-invasive procedure that can be carried out on an outpatient basis without anaesthesia.
  • Low rate of complications. Common surgically related complications such as intraoperative bleeding, infection and visceral damage do not occur.
  • Short treatment time
  • Short recovery time
  • Preserved fertility. Women of childbearing age are able to conceive and have normal pregnancies after treatment.

Important Information About HIFU Treatment

Before Treatment

  • Avoid sexual intercourse 3 days before treatment
  • Abdomen above the uterus area should be cleanly shaven
  • Bowel preparation

During Treatment

You will lie on your stomach on the treatment bed that slides into the opening on an MRI machine. A doctor will monitor and communicate with you from an adjoining room through a microphone.

Before treatment starts, MRI monitoring is first done repeatedly to ensure that the uterus remains in position above the transducer, in order to ensure that there are no interposed intestinal loops or other organs.

Using focused ultrasound waves, the fibroid is heated portion by portion. MRI is used to monitor the temperature of fibroid tissue and determine if the fibroid has been heated enough to achieve tissue necrosis.

After Treatment

Post-treatment, your body will gradually absorb the treated tissue over the course of the following months. In a period of 3 months or longer, a majority of the women who underwent HIFU treatments experience significant improvements in the severity of their symptoms.

Possible Postoperative reactions:

  • Slight inflammation of subcutaneous fat tissue and the abdominal muscles which can be managed with a doctor’s prescription of anti-inflammatory medicine.
  • Discharge of vaginal tissue
  • Irregular and/or increased bleeding up to 3 months post treatment
  • Temporary pain in the treatment area, lower abdomen, sacrum area and legs
