Visibility of Urinary Stones in Plain Kidney, Ureter and Bladder Radiographs and Computed Tomography Scout View With Correlation with CT Hounsfield Unit

Abstract

rinary calculus remains to be a common presentation in the hospital. It is the third most common urological problem after urinary tract infection and prostate disease with life time prevalence of urolithiasis at 10-15%.The prevalence has risen over a 20-year period from the mid 1970's to the mid 1990's. The diagnosis of urolithiasis is largely dependent on analyzing the clinical presentation and physical examination. Suspicion is confirmed with radiologic tests, particularly the non-contrast enhanced computed tomography scan. The advent of non-enhanced computed tomography has not only provided detection and confirmation of calculi, but also accurate detection of its size and location.
