Diagnostic Accuracy of Ultrasonography Versus Computed Tomography for Ureteric Calculi Among the Adult Patients Visiting Mayo Hospital Lahore

Background: Uretric calculi was most commonly found associated with ureteric colic. It occurs due to low fluid intake, frequent urinary tract infections and medicines that may crystallize within the urine. Ureteric calculi are mostly composed of calcium which crystallizes in the kidney and moves down to ureter causing obstruction. The prevalence of ureteric colic is increasing everyday. Over-utilization of Computed tomography is a growing health concern because of the used of high radiation in computed tomography. Objective: To determine the diagnostic accuracy of ultrasonography versus computed tomography for ureteric calculi among the adult patients visiting Mayo hospital Lahore. Methods: This Cross-sectional descriptive study was conducted in the Department of Radiology in Mayo hospital Lahore. All patients with ureteric colic (as per operational definition) and with suspicion of ureteric calculus were included. The ct-scan machine of Hitachi (164 slices) and Ultrasound machine Siemens was used to performing this research to determine the diagnostic accuracy of ultrasonography versus computed tomography for ureteric calculi among the adult patients. Ureteric stones were diagnosed on a trans-Abdominal scan by using of 5MHz frequency. Results: Total 78 patients with sign and symptoms of ureteric calculi were imaged with ultrasonography and computed tomography, among them ureteric calculi were found in 25 (34.2%) patients with ultrasound. Ureteric calculi were found in 52(71.2%) with computed tomography scanning. The individuals of 17-75 years were mainly involved while most of them were male patients. We observed that, computed tomography scanning is batter to diagnose ureteric calculi as compared to ultrasonography.
