USG FOR DETECTING RENAL CALCULI WITH NON-ENHANCED COMPUTED TOMOGRAPHY AS A REFE-RENCE STANDARD

The aim of this study was comparison of sensitivity and specificity of Computed Tomography and ultra-sound, to diagnose ureteral colic in those patients who present with lumbar pain. This study was conducted in Al-Noor Diagnostic Center, between 1st January, 2014 to 31st December, 2014. In this study 250 patients were investigated through imaging modalities i.e. CT and Ultrasound. Renal calculi were confirmed in 220 patients. The sensitivity of NECT was found 98% whereas of U/S was 73%. CT is the best and reliable technique to detect renal calculi however, Ultrasound was found preferred substitute to CT to lessen radiation dose.
