Vesicoureteric junction calculus

Case contributed by Dr Andrew Dixon


Left renal colic.

Patient Data

Age: 55 years
Gender: Male

A 5.0 x 5.5 mm obstructing left ureteric stone is seen at the vesicoureteric junction (VUJ).

Associated hydroureter and hydronephrosis which is mild to moderate in severity.

Left perinephric fat stranding.

Case Discussion

Typical CT appearance of renal colic with an obstructing stone at the left vesicoureteric junction associated with a degree of hydroureter, hydronephrosis and perinephric fat stranding. This is a very common location for a ureteric calculus to lodge. The vast majority of stones that are 4 mm or less will pass naturally into the bladder. This stone measures 5.5 mm, thus might require surgical extraction.
