Technique to displace bowel loops in MRI-guided high-intensity focused ultrasound ablation of fibroids in the anteverted or anteflexed uterus.

Abstract

In MRI-guided high-intensity focused ultrasound ablation of uterine fibroids, bowel interposition in the sonication path is often problematic. The purpose of this article is to discuss a bowel-manipulation technique to displace the bowel loop, which consisted of sequential applications of urinary bladder filling, rectal filling, and urinary bladder emptying. This technique contributed to a decreased screening failure rate and succeeded in consistently displacing the bowel loop, thus allowing safe treatment of fibroids in the anteverted or anteflexed uterus.
