Objectives:
The aim of the study was to evaluate the clinical efficacy of magnetic resonance-guided High-Intensity Focused Ultrasound (HIFU) in patients with symptomatic uterine fibroids (myomata) after application of oxytocin.
Methods:
156 women with symptomatic uterine fibroids were treated using MR-guided HIFU procedure. 51 patients had additional IV administration of 40 IU of oxytocin in 5% Glucose or 0,9% NaCl solution during therapy. Before and after the procedure we performed MR and measured initial perfused volume, final perfused volume, nonperfused volume (NPV), and treated volume ratio (TVR). The follow-up was up to 15 months to assess efficacy of treatment and relief of symptoms.
Results:
Nonperfused volume was statistically significantly larger in oxytocin group than in control group (p=0.0019). The remaining parameters did not show significant difference between both groups.
Conclusion:
Oxytocin administration seems to improve efficiency of HIFU therapy although further research is required to assess its value. This study' clinical registration number is DRKS00014794.
