An exploration of the Sonata System

When it comes to managing uterine fibroids, one of the latest, minimally invasive treatments available is the Sonata® System, a procedure that uses radiofrequency ablation to address fibroid-related symptoms effectively. For many women, fibroids can significantly affect their quality of life, causing symptoms such as heavy menstrual bleeding, pelvic pain, and bloating.

Leading consultant gynaecologist Mr Mohammad Masood, who is one of the few specialists in Essex to offer the treatment, discusses  how the Sonata System works, what to expect during the procedure, and whether it’s the right choice for you.

What is the Sonata procedure?

The Sonata procedure, formally known as the Sonata® System or transcervical fibroid ablation, is a non-surgical treatment for uterine fibroids that uses radiofrequency ablation (RFA) technology. In simple terms, RFA uses heat generated by radiofrequency energy to destroy the fibroid tissue, causing it to shrink over time. The procedure is performed through the vagina, without the need for any cuts or incisions in the abdomen.

This makes the Sonata procedure a minimally invasive option compared to traditional surgical methods, such as myomectomy or hysterectomy, which involve physically removing the fibroids or even the entire uterus. The treatment is suitable for a variety of fibroid types, including submucosal, intramural, and transmural fibroids. However, not all fibroids are eligible for this procedure, and your gynaecologist will assess whether the Sonata System is appropriate for your specific condition.

How does the Sonata System work?

During the Sonata procedure, a small, handheld device is inserted through the vagina and into the uterus. This device uses ultrasound guidance, which allows the doctor to see the fibroids in real-time. Once the fibroids are located, radiofrequency energy is delivered directly to each fibroid, heating the tissue to a temperature that causes it to break down gradually.

Because the device includes an ultrasound imaging tool, the doctor can treat the fibroids precisely, minimising the impact on the surrounding healthy tissue. Over time, the fibroids treated with radiofrequency energy shrink and are reabsorbed by the body. Most patients start to notice an improvement in their symptoms within a few months, with the full effect of the treatment often evident by six months after the procedure.

What are the benefits of Sonata radiofrequency ablation?

One of the primary benefits of the Sonata System is that it is a minimally invasive alternative to more traditional surgical approaches. Since no incisions are made, recovery time tends to be shorter, and there is a lower risk of complications. Patients often experience less postoperative pain, and many are able to return to normal activities within a day or two.

The Sonata procedure can also preserve fertility for some patients, which is an important consideration for those who may wish to have children in the future. However, the effects on fertility depend on the individual and should be discussed in detail with your doctor before undergoing the treatment. Additionally, Sonata may help in reducing heavy menstrual bleeding, which is one of the most common symptoms associated with fibroids.

Who is a good candidate for the Sonata procedure?

The Sonata procedure is generally considered for women who have symptomatic fibroids that cause issues such as heavy menstrual bleeding, pelvic pain, or pressure in the abdomen. It’s ideal for patients seeking an option that doesn’t involve major surgery. Women who are close to menopause but still suffer from fibroid symptoms may also benefit from this treatment, as the fibroids are likely to shrink even more post-menopause.

However, not all patients are candidates for this treatment. For instance, if you have very large fibroids or certain types of fibroid growth patterns, the Sonata System may not be the most effective option. Your gynaecologist will conduct a thorough examination, possibly including an ultrasound or MRI scan, to determine if your fibroids are suitable for treatment with Sonata.

What can you expect during and after the procedure?

The Sonata procedure is typically performed on an outpatient basis, meaning you can go home the same day. It’s usually done under mild sedation or local anaesthesia to keep you comfortable, but you’ll remain awake. The procedure itself takes about 45 minutes to an hour, depending on the number and size of the fibroids being treated.

After the treatment, you may experience mild cramping or spotting, similar to menstrual cramps, which can usually be managed with over-the-counter pain relief. Most patients can return to their normal activities within one to two days, making Sonata a convenient option for those with busy lifestyles. While some women notice an improvement in their symptoms almost immediately, it can take up to three to six months to feel the full benefits as the fibroids gradually shrink.

Choosing a treatment option for fibroids is a personal decision and one that should be made after careful consideration of your individual needs and lifestyle. If you think the Sonata procedure might be right for you, consult with your gynaecologist to discuss your options and to ensure that it aligns with your health goals.
