Uterine fibroids are common uterine benign neoplasm. They can cause abnormal menstrual bleeding, pelvic discomfort and urinary frequency. Although surgical intervention is the definitive treatment, some women prefer to have their uterus preserved. High-intensity focused ultrasound (HIFU) therapy is receiving increasing interest in the management of uterine fibroids by inducing focal thermocoagulation of the fibroids. Results obtained by various research groups have shown that HIFU treatment is safe, effective and is highly acceptable to patients. The main objective of this study is to evaluate the therapeutic efficacy of HIFU in the treatment of uterine fibroids.
