Efficacy and Safety of Transvaginal High-Intensity Focused Ultrasound Therapy in Women with Symptomatic Uterine Leiomyomas: A Clinical Trial
Dr. Jae Young Lee and colleagues at Seoul National University recently published the results from a clinical trial using a novel approach and device to treat patients with uterine fibroids: transvaginal high-intensity focused ultrasound (vHIFU).
Thirteen premenopausal women with 33 contrast-enhanced, less than 5-cm uterine leiomyomas participated in the study, which took place at two centers over a period of 14 months. The researchers used Alpinion Medical Systems’ RODIN HIFU system with sedation or monitored anesthesia. The RODIN system has a positioning module, two imaging probes (one transabdominal and one transvaginal), and one vHIFU treatment probe. The primary endpoint was the non-perfused volume (NPV) ratio measured immediately after therapy, and it surpassed the non-inferiority cutoff of 0.5 by reaching 0.76 ± 0.27 (mean ± SD). Secondary endpoints of quality-of-life scores, dysmenorrhea, and fibroid volume all showed significant improvement. Eight of the participants experienced adverse events that resolved without sequelae and none required subsequent therapy.
