Predictive scoring systems have been suggested to aid decision\u2010making and reduce unnecessary imaging; however, their accuracy has been challenged. This study aimed to assess the diagnostic performance of the STONE score and modified STONE score (MSS) in predicting ureteric calculi in an Australian population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Retrospective cohort study of patients aged &gt;\u200918\u2009years, who were suspected of having ureteric colic and underwent CT renal tract.

The STONE score demonstrated an AUC of 0.806 (95% CI 0.745\u20130.862), and the MSS had an AUC of 0.796 (0.734\u20130.858) for predicting ureteric stones. If the high score (high probability urolithiasis) group patients had not undergone a CT scan, 8.9% of scans could have been avoided if the STONE score was applied compared to 54.8% with the MSS (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0004).
