Three-dimensional saline-infusion sonohysterography is useful for the identification of endometrial polyp

Abstract

Aim: To determine whether three-dimensional saline infusion sonohysterography (3D-SISH) is useful for the detection of endometrial polyps and whether it can accurately identify the site of attachment within the uterine cavity.

Methods: Sixteen women who underwent preoperative magnetic resonance imaging (MRI), 3D-SISH and subsequent hysteroscopic resection or total hysterectomy and who were surgically diagnosed with endometrial polyps were enrolled. The rate of polyp detection and the accuracy of attachment site within the uterine cavity for each test were examined.

Results: Endometrial polyps could only be identified in 37.5% of women using MRI, but could be identified in all women using 3D-SISH. The accuracy rate of the attachment site of endometrial polyps was 87.5% on 3D-SISH and 18.8% (in all patients) or 50.0% (in polyp-detected patients) on MRI, indicating a higher accuracy rate using 3D-SISH.

Conclusion: We demonstrated that 3D-SISH is useful for the detection and localization of endometrial polyps and is likely to become the examination method of first choice for the identification of endometrial polyps.
