CT kidneys, ureters and bladder (protocol)
Updates to Article Attributes
Body
was changed:
Computed tomograpy Kidneys, Ureters, Bladder (CT KUB) is a quick non-invasive technique for diagnosis of urolithiasis.
Advantages
- quick
- easily accessible
- identification of calcified renal tract calculi
sizeandpositionstone composition assessment with dual energy CT
assessment of the sequelae of calculiassessement of other causes of flank pain if negative for calculus disease
Disadvantages
- exposure to ionizing radiation
Technique
Procedure
Actual procedure will vary depending on institutional protocol/guidelines but below is a typical description:
- Non 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
