"Computed tomography of kidneys, ureters and bladder (CT KUB) is a quick non-invasive technique for diagnosis of urolithiasis. It is usually considered the initial imaging modality for suspected urolithiasis in an emergency setting 1."
"The purpose of CT KUB is primarily to assess for the presence of urolithiasis. Location of the stone, size, and secondary signs of renal tract obstruction can then be used to gauge the likelihood of passage and guide further management 3."
"NB: This article is intended to outline some general principles of protocol design. The specifics will vary depending on CT hardware and software, radiologists' and referrers' preference, institutional protocols, patient factors (e.g. allergy) and time constraints."
