Ureteric colic diagnosis by plain radiography and ultrasound by taking CT-KUB as Gold Standard.

Abstract

Objective: To assess the sensitivity and specificity of ultrasound, plain radiography, and CT for diagnosing ureteral colic in individuals with acute flank pain. Study Design: Cross-sectional Research. Setting: Department of Radiology, PAF Hospital, Islamabad, Pakistan. Period: August 2022 to February 2023. Methods: The study included 150 individuals with an average age of 40.68 years. Pre-procedural imaging modalities included plain radiography (X-ray KUB), ultrasound (U/S), and CT. Results: Ureteral stones were confirmed in all 150 cases. CT demonstrated 100% sensitivity and specificity. X-ray KUB had a sensitivity of 90%, while ultrasound had a sensitivity of 74%. Some stones were missed by ultrasound due to interference from intestinal gases, and a few were not identified on X-ray KUB. Conclusion: All three modalities successfully diagnosed ureteral stones. While CT is the most accurate diagnostic tool, X-ray KUB and ultrasound can be considered as alternatives, especially in settings requiring lower radiation exposure.
