Diagnostic Accuracy of Doppler Ultrasound in the Diagnosis of Testicular Carcinoma by Taking Histopathology as Gold Standard

Abstract

Objective: To determine the diagnostic accuracy of doppler ultrasound in the diagnosis of testicular carcinoma, by taking histopathology as gold standard.
 Methods: This cross-sectional study was carried out at Radiology department of Liaquat University of Medical and health Sciences (LUMHS), from November 2017 to October 2019. All the clinically diagnosed cases of testicular carcinoma, those who referred for doppler ultrasound and histopathology of testes, were included. After taking informed consent all the study participants underwent testicular histopathology after doppler ultrasound. All of the information was entered into a research proforma. SPSS version 20 was used to analyze the data.
 Results: Overall, 70 patients of suspected testicular carcinoma were studied. The mean age of the cases was 38.38+4.55 years. Most of the cases 47(67.1%) were poor. As per Doppler ultrasound (U/S) findings out of all 55.7% cases had diagnosed testicular carcinoma, while histopathologically it was observed in 45.7% of the cases. Diagnostic accuracy of Doppler U/S in testicular carcinoma diagnosis was observed to be 77%, followed by sensitivity (SE) 84%, specificity (SP) 71%, positive predictive value (PPV) 78% and negative predictive value (NPV) 84%.
 Conclusion: Doppler ultrasound observed to be a non-invasive, uncomplicated, lack of pain, effective and easily available diagnostic tool for early diagnosis of testicular carcinoma.
