ABSTRACT
The aim was to determine the diagnostic accuracy of sonography for ovarian torsion. In this analytic descriptive study, 323 women with suspected ovarian torsion underwent a transabdominal sonography. Findings of sonography were compared with laparatomy. 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. Sonography is excellent to evaluate patients with suspected ovarian torsion. Abnormal blood flow is highly predictive of ovarian torsion
