Validity of Color Versus Spectral Doppler Ultrasound Indices in Post-Surgical Cases of Testicular Torsion

Objective:To evaluate the diagnostic accuracy of Color Doppler and Spectral Doppler ultrasound indices in detecting testicular torsion in post-surgical cases. Methods:A retrospective study was conducted over six months in the Department of Radiology, Benazir Bhutto Hospital, Rawalpindi. Seventy-one male patients with clinical suspicion of testicular torsion were assessed using both Color and Spectral Doppler ultrasound. Findings were compared with surgical exploration results. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated. Results:The mean patient age was 15.2 years. Of 71 patients, 56 (78.9%) were diagnosed with torsion on ultrasound, and 60 (84.5%) were confirmed surgically. Color/Spectral Doppler demonstrated 91.66% sensitivity, 90.9% specificity, PPV of 98.21%, NPV of 66.6%, and an overall diagnostic accuracy of 91.5%. Conclusion:Color and Spectral Doppler ultrasound are highly sensitive and specific, offering reliable, non-invasive diagnostic modalities for post-surgical evaluation of testicular torsion. Their appropriate use can prevent unnecessary surgical exploration and improve clinical outcomes.
