Background : The aim was to determine the diagnostic accuracy of sonography for ovarian torsion.
Materials and Methods : In this analytic descriptive study, 323 women with suspected ovarian torsion underwent a transabdominal sonography. Findings of sonography were compared with laparatomy.
Results : The ultrasound correctly diagnosed 72.1% of ovarian torsion cases and missed 27.9% of these cases (false negatives). There was a strong correlation between sonography and surgery with a kappa value of 84.0%. The sensitivity and specificity of sonography for diagnosing ovarian torsion were determined 72.1% and 99.6%, respectively. Also, sonography had a positive predictive value (PPV) of 96.9%, a negative predictive value (NPV) of 95.9%, and a total accuracy of 96.0% for detection of ovarian torsion.
Conclusion : Sonography is excellent to evaluate patients with suspected ovarian torsion. Abnormal blood flow is highly predictive of ovarian torsion.
Keywords: Torsion, Sensitivity, Specificity, Ultrasonography
