Reporting Groups
  Description
HIFU Treated Women indicated for total abdominal hysterectomy underwent a single Magnetic Resonance guided-High Intensity Focused Ultrasound (MR-HIFU) session for uterine fibroid ablation prior to surgery. Subjects were followed up until the date of hysterectomy, or for 30 days if hysterectomy was declined.

  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Treatment-related Adverse Events (AE) Per Subject Resulting From HIFU Treatment of the Uterine Fibroids   [ Time Frame: end of follow-up (date of hysterectomy, at latest day 30 after treatment) ]

2.  Secondary:   HIFU Treatment Equals Location Per Hysterectomy   [ Time Frame: Day 0, Hysterectomy ]

3.  Secondary:   Length of Time to Return to Normal Activities   [ Time Frame: end of follow-up (date of hysterectomy, at latest day 30 after treatment)] ]

4.  Secondary:   Numerical Range Scale (NRS) of Pain Level   [ Time Frame: Treatment Day: Baseline, Recovery, Discharge; Follow-up: 24 hours, 48 hours, 72 hours, 1 week, 2 weeks ]

5.  Secondary:   Discomfort Level   [ Time Frame: Treatment Day: Baseline, Recovery, Discharge; Follow-up: 24 hours, 48 hours, 72 hours, 1 week, 2 weeks ]
