Correct Answer � D
Explanation

Ans:D.)Ureteric Calculi.
Image shows:
- First: KUB shows a radio-opacity (arrow) in the left paravertebral region at the level of L4, along the course of the left ureter. This was confirmed to be a ureteric calculus.
- Second: A tomogram obtained during the IVU examination shows left hydronephrosis (dilated renal calyces (arrowheads) and pelvis (open arrowheads)), and proximal hydroureter (open arrows). The ureteric stone (arrow) is situated at the lower end of the dilated left ureter.
URETERIC CALCULUS
- Ureteric stones are renal stones that have passed down the pelvicalyceal system and become lodged within the ureter. The majority of them are therefore radio-opaque. IVU is usually the second investigation after a KUB.
