Diagnostic failures in ovarian torsion during childhood: The effect of ovarian cyst size on the diagnostic accuracy of Doppler ultrasonography

Purpose To determine the diagnostic accuracy of Doppler ultrasonography (US) in pediatric ovarian torsion (OT) and the effect of ovarian cyst size on the effectiveness of Doppler US in pediatric OT. Methods We retrospectively reviewed of the data of 84 patients (4–17 years) operated with the preliminary diagnosis of OT from January 2007 to December 2019. Patients' demographic characteristics, clinical signs and symptoms, laboratory and radiologic findings, operative management, histopathological results, and postoperative complications were recorded. Results OT was surgically confirmed in 53 (63%) patients. In 30 patients without ovarian cyst, Doppler US suggested OT in 16 out of 22 patients with surgically confirmed OT. In 12 patients with ovarian cysts
