OBJECTIVE: To evaluate the diagnostic accuracy of combined vaginal and abdominal color Doppler ultrasonography for ovarian cyst torsion.
METHODS: In a cross-sectional diagnostic study from January 2019 to October 2023, 86 patients suspected of ovarian cyst torsion were assessed using vaginal and abdominal ultrasonography. Pathological findings were the gold standard. Diagnostic performances were analyzed using ROC curves.
RESULTS: Vaginal ultrasonography had a sensitivity of 76%, specificity of 61%, and AUC of 0.686. Abdominal ultrasonography showed a sensitivity of 72%, specificity of 50%, and AUC of 0.610. Combined use resulted in improved sensitivity (84%), specificity (72.2%), and the highest AUC (0.781). The combined method significantly outperformed abdominal ultrasonography in accuracy and AUC.
CONCLUSION: Vaginal ultrasonography alone is more accurate than abdominal ultrasonography for diagnosing ovarian cyst torsion. The combination of both methods enhances diagnostic precision, offering significant benefits for early diagnosis and treatment planning.
