Computed Tomography (CT) of the Kidneys, ureter, bladder is prime investigation to study the pathologies ofthe Genitourinary system. Despite the advantages of CT, radiation exposure poses major risk. The objectiveof the review is to investigate the effectiveness of Low dose dose CT over standard dose CT for detectionof Urolithiasis. The literature search was performed on PubMed, Scopus, CINHAL, Cochrane Library andWeb of Science databases for original research articles published between 2000 and 2020. Research Articlesthat included the efficacy of low dose CT over standard dose CT in identification of Urinary stones wereincluded. Total 4558 studies were detected from the literature search. After thorough screening 12 articleswere included in the review. The Sensitivity of Low dose CT KUB was 80 to 99% and the Specificity rangedfrom 88 to 100%, the diagnostic accuracy of Low dose CT was 96.1%. From our study we conclude thatLow dose CT KUB was effective in maintain the diagnostic confidence with optimal image quality andreduced radiation dose.
