Effectiveness of Low Dose Over Standard dose CT for Detection of Urolithiasis: A Systematic Review

Abstract

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