High-intensity focused ultrasound (HIFU) treatment for uterine fibroids: a meta-analysis.

PURPOSE: High-intensity focused ultrasound (HIFU) is a non-invasive uterine-preserving treatment alternative to hysterectomy for women with fibroids.

METHODS: We performed this meta-analysis to evaluate the efficacy of HIFU in the treatment of women with symptomatic fibroids comparing it to other approaches including medical treatment with mifepristone (Mife), traditional surgery with myomectomy or hysterectomy (MYC/HRM), and radiofrequency ablation (RF). 16 studies with 1725 women were included.

RESULTS: The pooled data of HIFU comparing it to other methods in terms of complete or partial response rate (CR/PR) was not significantly better, but in subgroup analysis, the response rate was significantly higher than Mife, significantly lower than RF and comparable to MYC/HRM, respectively. For the endpoints of safety, the superiority of HIFU compared to MYC/HMR or Mife was found to be significant in terms of pain/discomfort, fever, transfusion, genital tract, gastrointestinal tract, and anesthesia-related complications, while no superiority was identified for skin burn, urinary tract, and nervous system complications.

CONCLUSION: These results suggest that HIFU treatment of uterine leiomyomas leads to clinical improvement with few significant clinical complications and adverse events.
