Diagnostic accuracy of ultrasound in renal masses taking computed tomography as a gold standard

Objective: To evaluate diagnostic accuracy of ultrasound in renal masses taking computed Tomography as a gold standard. Methodology: A cross-sectional study of 198 study subjects with renal masses was conducted at District Head Quarter Hospital (DHQ) and Allied Hospital, Faisalabad. Patients of age 18 years and above and of both genders with complaints of hematuria and/or palpable mass in the flank region was included. Patients with nephrolithiasis, any other gross renal pathology and patients with any contraindication to the contrast agent, were excluded. Results: Ultrasound had the Sensitivity of 76.67%, Specificity of 100%, positive predictive value of 100%, negative predictive value of 80.56%, and the diagnostic accuracy of 88.14% respectively for the assessment of renal cell carcinoma. Conclusion: Ultrasound is a reliable tool for the differentiation of renal masses, and other renal pathologies such as simple cysts, complex cysts, and polycystic kidney disease.
