Heavy menstrual bleeding and dysmenorrhea are improved by Magnetic Resonance Guided Focused Ultrasound Surgery (MRgFUS) of adenomyosis.

BACKGROUND

To assess reduction in heavy menstrual bleeding and dysmenorrhea following MRI guided Focused Ultrasound Surgery (MRgFUS) of focal and diffuse adenomyosis up to 12 months post-treatment a retrospective cohort study was done at a tertiary care academic medical center for obstetrics, gynecology and infertility.

METHODS

MRgFUS for adenomyosis uterus was done for thirty-seven patients presenting with symptoms of heavy menstrual bleeding and dysmenorrhea with MRI-suspected adenomyosis. The main outcome measure, was reduction in heavy menstrual bleeding, dysmenorrhea and Symptom Severity Scoring (SSS) over a 3, 6 and 12 month period. Secondary outcome was evidence of fertility preservation post procedure. D'Agostino & Pearson omnibus normality test, one-way Ananova, Pearson's correlation coefficient analysis was performed on the data. Statistical significances, p-value and r-value were determined.

RESULTS

Out of 37 patients who were treated by MRgFUS, 26 had sufficient follow-up to be included in the analysis. SSS calculated at 3, 6 and 12 months was significantly over the baseline. Both heavy menstrual bleeding and dysmenorrhea, which were assessed separately, were found to significantly improve over time with a positive correlation between the two. No other intervention was required.

CONCLUSION

MRgFUS provides immediate and sustained relief for patients with focal and diffuse adenomyosis.
