Is Two-Dimensional Saline Infusion Sonohysterography (2D SIS) an Accurate Tool in Evaluation of Uterine Cavity in Infertile Patients in Reference to Office Hysteroscopy?

Objective: To asses the accuracy of two-dimensional saline infusion sonohysterography (2D SIS) office hysteroscopy in evaluation of uterine cavity in infertile patients. Patients and Methods: 100 patients with suspected uterine lesion were recruited in the study. Suspected uterine lesion was based on the history, clinical examination or previous investigations suggesting uterine cavity abnormality including congenital uterine anomalies (Müllerian anomalies), intrauterine adhesions or uterine cavity pathology (polyps, myomas ...). All patients underwent, 2D saline infusion sonography (2D SIS) and office hysteroscopy. Results: The overall accuracy was 91% for 2D sonohysterography. The accuracy of 2D sonohysterography in detection of endometrial polyp was 100%. The accuracy of the modality in detection of uterine anomalies was 100% for 2D sonohysterography. The accuracy of the modality in detection of intrauterine adhesions was 86.67% for 2D sonohysterography. Conclusion: Two-dimensional saline infusion sonohysterography (2D SIS) is an accurate tool in evaluation of uterine cavity especially endometrial polyp and uterine anomalies.
