Objective: To determine the accuracy of unenhanced Computed tomography in diagnosis of urolithiasis in the suspected patients in which diagnosis of urolithiasis was missed on intravenous pyelogram

Study Design: Cross-sectional Observational study

Place and Duration: At Department of Radiology, Liaquat University of Medical Health Sciences, Jamshoro, Hyderabad from 1st March 2018 to 31st December 2018

Methodology: Outdoor symptomatic patients who were negative on intravenous pyelography for urolithiasis were re-assessed by unenhanced CT scan KUB procedure. The frequency of urolithiasis on CT KUB, previously missed in IVU, precision of investigation in terms of site, size, number of stone assessed.

Results: Among total of 386 symptomatic patients with negative IVP 63.2% showed urolithiasis whereas 36.8% were found negative for urolithiasis. The most common site of single calculus was ureter (35.2%) and most common transverse size of the stone was in between 0.4 to 0.5 cm (37 to 41 cases, 9.6% to 10.6%). Presence of multiple stones (57.3%) were more common in kidney and single stones (35.2%) were more common in ureter.

Conclusion: Unenhanced CT Scan KUB provides more efficient information in patients, presenting with acute renal colic. It has significantly higher rate of diagnosing urolithiasis in comparison with intravenous pyelogram.
