Diagnostic Accuracy of Color Doppler & Grey Scale Ultra-sonography in the Diagnosis of Painful Scrotal Conditions.

Background: Acute scrotal pain is most commonly caused by testicular torsion, torsion of the appendix testis, epididymitis and orchitis. Its complications can be diagnosed on Ultrasound and histopathology for surgical procedures. Objective: To find out the diagnostic accuracy of color Doppler ultrasound for the diagnosis of painful scrotal by taking histopathology as the gold standard. Methodology: It was across-sectional observational study conducted on 141 patients of scrotal masses that fulfilling inclusion criteria selected from Gondal Medical Complex Gujranwala. Informed consent was obtained from all the patients. All patients were scanned on Toshiba Nemio 20 series with 11MHz biconvex and linear transducers. Diagnostic accuracy was determined by comparing it with the findings of histopathology by taking histopathology as the gold standard. Results: In this study, the mean age of patients was 37.0 ± 11.58 years. All the patients were subjected to histopathology. Amongst them 61 (43.3%) patients had positive results and 80(56.74%) patients were diagnosed negative. On Color Doppler ultrasonography, 64 (45.4%) patients had positive, while 77(54.6%) negative findings. The sensitivity, specificity, positive and negative predictive values of Doppler sonography were 70.49%, 73.75%, 67.19% and 76.62% respectively. This study showed that the overall diagnostic accuracy of Doppler ultrasonography was 72.34%. Conclusion: Doppler ultrasonography can be reliably being used to detect painful scrotal. Doppler ultrasound is an effective and non-invasive technique as a primary diagnostic tool to get rid of excessive surgery burden. [ABSTRACT FROM AUTHOR]
