Objective:
To evaluate the long-term improvement of clinical symptoms of adenomyosis after treatment with ultrasound-guided high intensity focused ultrasound (USgHIFU).
Methods:
From January 2010 to December 2011, 350 patients with adenomyosis were treated with USgHIFU. Among the 350 patients, 224 of them completed the two years follow-up. The patients were followed up at 3 months, 1 year, and 2 years after HIFU treatment. Adverse effects and complications were recorded.
Results:
All patients completed HIFU ablation without severe postoperative complications. 203 of the 224 patients who showed varying degrees of dysmenorrhea before treatment had the symptom scores decreased significantly after treatment (P<0.001). The relief rate was 84.7%, 84.7%, and 82.3%, respectively at 3 months, 1 year, and 2 years after treatment. The menstrual volume in 109 patients with menorrhagia was significantly improved after treatment (P<0.001) with a relief rate of 79.8%, 80.7%, and 78.9%, respectively at 3 months, 1 year, and 2 years after HIFU treatment.
Conclusion:
With its ability to sustain long-term clinical improvements, HIFU is a safe and effective treatment for adenomyosis.
