Updates to Article Attributes
Body
was changed:
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.
Advantages
- quick
- easily accessible
- identification of calcified renal tract calculi and their sequelae
- assessment of other causes of flank pain if negative for calculus disease
Disadvantages
- exposure to ionizing radiation
Technique
Procedure
ActualThe actual procedure will vary depending on institutional protocol/guidelines but below is a typical description:
- non
contrast-contrast CT scanning is ideally performed on a multi-detector computed tomography (MDCT) scanner. - supine or prone patient positioning
- prone has the advantage of assessing stones near the VUJ which may have just passed
- some institutions may perform a limited pelvic scan in prone if the supine scan shows a calculus near the VUJ
- data interpretation with the use of axial, sagittal and coronal reformatted images for proper evaluation.
Findings
- identification of calcified renal tract calculi size and position
- stone composition assessment with dual energy CT
- assessment of the sequelae of calculi
- obstruction
- infection
- assessment of other causes of flank pain if negative for calculus disease
- presence of further calculi at risk of obstructing
