'''Kidney stone disease''', also known as '''urolithiasis''', is when a calculus (kidney stone) occurs in the [[urinary tract]].<ref name=NIH2013>{{cite web|title=Kidney Stones in Adults|url=http://www.niddk.nih.gov/health-information/health-topics/urologic-disease/kidney-stones-in-adults/Pages/facts.aspx|accessdate=22 May 2015|date=February 2013|deadurl=no|archiveurl=https://web.archive.org/web/20150511192215/http://www.niddk.nih.gov/health-information/health-topics/urologic-disease/kidney-stones-in-adults/Pages/facts.aspx|archivedate=11 May 2015|df=dmy-all}}</ref>

===Choice of exam=Recurrent==*See '''[[Ultrasonography of the urinary system]]''' is the first-line imaging modality for patients <14 years of age and those who are pregnant. It is also the first-line investigation for thin (BMI <30) patients and there is a strong suspicion of CT in recurrent kidney stone disease.<ref name="BrisbaneBailey2016"/>*'''[[Abdominal CT]]''' is recommended for older patients, as well as those who have higher BMI and/or less specific findings.<ref name="BrisbaneBailey2016"/>
