Brief Summary:

The objective of this trial is to evaluate the safety and efficacy of ExAblate for the treatment of uterine fibroids.

Women, seeking treatment for symptomatic uterine leiomyomata will be eligible for the study.Women who agree to participate will sign an informed consent and will be randomized to ExAblate treatment or myomectomy.

All patients will be followed through the 36 month visit. Follow-up visits/telephone calls will be completed at 1 week, 2 weeks, 6 weeks, 3 months, 6, 12, 18, 24 and 36 months post treatment.

Patients will be evaluated by assessing their overall physical and mental health as well as for device/procedure related adverse events.

Arm Intervention/treatment
Active Comparator: Treatment
MR guided Focused Ultrasound
Device: Exablate 2100

Active Comparator: Surgery
Procedure: Myomectomy
Non-Hysteroscopic Myomectomy

Primary Outcome Measures :
  1. Safety [ Time Frame: 36 months post treatment ]
    Safety will be evaluated by recording and assessing the incidence and severity of major adverse events from treatment through the 3 years follow-up period.

  2. Efficacy [ Time Frame: 36 months post treatment ]
    Comparison between ExAblate treatment and non-Hysteroscopic Myomectomy in terms of treated patients who did not undergo another interventional treatment for recurrence of uterine fibroid symptoms at up to 36 months (3 years).

Secondary Outcome Measures :
  1. Efficacy [ Time Frame: 36 months post treatment ]
    1. Post treatment change in patient's quality of life
    2. Post treatment change in pelvic pain
    3. Post treatment Change in bleeding
    4. Post treatment recovery time
