Left renal tract calculi

Case contributed by Derek Smith
Diagnosis certain

Presentation

Intermittent left flank pain, now acute. Hematuria on dipstick. Normal inflammatory markers.

Patient Data

Age: 60 years
Gender: Female

CT KUB

ct

3 mm left distal ureteric calculus. This is close to the VUJ and is not obstructing the collecting system, although there is periureteric inflammatory change likely due to recent passage.

Further dense left interpolar calculus.

Hepatic cysts and left femoral fixation, otherwise unremarkable.

Annotated image

Calculus close to the left VUJ arrowed.

XR KUB

x-ray

Left renal and small left distal ureteric calculi evident on plain radiograph.

Case Discussion

CT KUB is a quick and relatively low dose test when there is high suspicion of renal tract calculi.

Follow up / assessment of passage is typically performed with plain radiographs. These calculi are visible on XR so this will be sufficient in future.
