ObjectiveTo assess the changes in antimüllerian hormone (AMH) levels after ablation for symptomatic uterine fibroids and adenomyosis using ultrasound-guided high-intensity focused ultrasound (USgHIFU).DesignA prospective study.SettingGynaecological department in multiple hospitals in South Korea.PopulationPatients with uterus fibroids and adenomyosis.MethodsSeventy-nine women with symptomatic uterine fibroids and adenomyosis who met the inclusion criteria were enrolled in our study between January 2014 and December 2014. All patients underwent USgHIFU ablations. Each patient was examined before and after treatment, and at 6 and 12 months after treatment by T2-weighted MRI imaging (T2WI) and T1-weighted MRI imaging (T1WI) with gadolinium injection. Symptom severity scores (SSS), Uterine Fibroid Symptom Quality of Life (UFS-QOL) questionnaire subscales, and reductions of treated volume were assessed. AMH levels before and 6 months after HIFU ablation were compared to determine whether USgHIFU ablation affected ovarian reserve.Main Outcome MeasuresHIFU treatment did not affect the ovarian function.ResultsHIFU treatment time (mean ± standard deviation), HIFU ablation time, and treatment energy were 73.5 ± 25.6 minutes, 9994.7 ± 386.8 seconds, and 364 713.8 ± 156 350.7 Joules, respectively. AMH levels before and 6 months after HIFU ablation were 2.11 ± 2.66 and 1.84 ± 2.57 μg/l, respectively. There was no significant difference in AMH level between the two time points (P > 0.05).ConclusionsUSgHIFU ablation for uterine fibroid and adenomyosis was effective without affecting ovarian reserve.Tweetable AbstractHIFU ablation is a safe and effective treatment for patients with uterine fibroids and adenomyosis that does not affect ovarian function.© 2017 Royal College of Obstetricians and Gynaecologists.
