Passed stone (CT KUB)

Case contributed by Dr Balint Botz


Left-sided renal colic, nausea and vomiting.

Patient Data

Age: 35 years
Gender: Male

Numerous small, hyperdense stones in bilateral collecting systems.

An about 2-3 mm calculus is visible adjacent to the left ureteropelvic junction.

No sign of hydronephrosis, perirenal or periureteral fat stranding. 

Case Discussion

Status post passage of a small renal calculus without sequelae. Though its exact position regarding the vesicoureteric junction cannot be determined clearly, the absence of collecting system dilation and secondary changes makes ongoing obstruction extremely unlikely, thus - considering the age of the patient - prone rescanning was avoided.
