Comparison of Saline Infusion Sonohysterography and Hysteroscopy Findings in Patients With Abnormal Uterine Bleeding

Objective: To establish the accuracy of saline infusion sonohysterography and hysteroscopy in diagnosing uterine pathology in women with abnormal uterine bleeding. Materials and Methods: A total of 39 women with abnormal uterine bleeding were recruited for the study and underwent transvaginal ultrasonography followed by saline infusion sonohysterography. During hysteroscopy, resection of the focal intracavitary lesion was performed. Endometrial sampling was obtained from all patients. Results: Sonohysterographic and hysteroscopic evaluation revealed 25 and 24 endometrial polyps, 7 each submucous myomas, 3 and 1 endometrial hyperplasia, 1 each synechia, and 3 and 6 normal findings, respectively. Comparison of histopathologic findings with other diagnostic tests revealed that hysteroscopy demonstrated a sensitivity of 97%, specificity of 72%, positive predictive value of 94%, negative predictive value of 83% and total sensitivity of 92%. Sonohysterography showed sensitivity of 97%, specificity of 29%, positive predictive value of 86%, negative predictive value of 85% and total sensitivity of 85%. Conclusion: In comparison with hysteroscopy, sonohysterography is a cheaper and easier procedure for detecting endometrial pathologies such as endometrial polyps and submucous myomas with its highly diagnostic value.
