Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Assessment of the safety and tolerability of local HIFU treatment in symptomatic uterine fibroids based on the number of adverse events occuring according to standardized protocols: incidents and product defects, adverse events or severe adverse events after HIFU classified according to CTCAE V5.0 (grade 1-5). In addition to the frequency of adverse events according to CTCAE V5.0, the following possible therapy-associated side effects are explicitly recorded: - Pain sensation during and immediately after HIFU (measured on the Visual nalog Scale 0-10, with 0 indicating "no pain", and 10 indicating "strongest pain imaginable"), - Pain sensation on the first post-interventional day (VAS 1-10) - Skin edema, skin redness, skin burn - Cystitis, vaginal discharge, vaginal bleeding - Ascites | — |
Secondary
| Measure | Time frame |
|---|---|
| -Evaluation of symptom severity score (SSS) and health-related quality of life score using UFS-QOL questionnaire (baseline scores versus scores 1 week, 3 months, and 6 months after HIFU procedure) -Evaluation of fibroid volume using MRI measurements (baseline volume versus volume 1 week, 3 months, 6 months after HIFU procedure) -Evaluation of the correlation between intervention parameters (sonication time, treatment time, total energy, energy per ml fibroid volume), achieved non-perfused volume, fibroid type according to Funaki classification, fibroid shrinkage over time -Evaluation of tissue stiffness properties of uterine fibroids using elastography measurements on ultrasound and MRI before and after HIFU procedure -Effects of HIFU treatment on blood parameters and early immune response | — |
