Abstract

Urolithiasis is a common clinical condition, with kidney and ureteric calculi being the most frequently encountered types. Ultrasound (USG) and CT Intravenous Pyelogram (CT IVP) are commonly used diagnostic modalities for detecting urolithiasis. This study aimed to evaluate and compare the sensitivity, specificity and diagnostic accuracy of USG and CT IVP in detecting lower ureteric and renal calculi. A total of 110 patients were enrolled in this study between December 2016 and September 2018. Patients aged between 18 and 75 years were examined using both USG and CT IVP for the detection of lower ureteric and renal calculi. The results from both modalities were analyzed, focusing on the detection rates, sensitivity, specificity and predictive values. Out of 110 patients, CT IVP detected 61 patients (55.45%) with lower ureteric calculi, while USG detected only 10 patients (9%). CT IVP showed a sensitivity of 99.99% and specificity of 100%, whereas USG demonstrated a low sensitivity of 18.87% and a high specificity of 100%. The positive predictive value of CT IVP was near‐perfect (100%), while the negative predictive value for USG was low (15.69%). This study confirms that CT IVP remains the gold standard for detecting urolithiasis due to its high sensitivity, specificity and diagnostic accuracy. USG, while specific, has limited sensitivity and should not be relied upon for comprehensive detection of lower ureteric calculi. The poor performance of USG is attributed to factors such as body habitus, bowel gas and operator‐related errors.
