Question 8

How could you know renal pelvis obstruction by CT

Answer 8

CT axial abdomen with IV contrast
Rt side : dilated pelvis with reduced cortical enhancement

( RT renal pelvis obstruction )

Punctate calcification occupying the renal parenchyma

“ indicate Hypercalcemial”

Same as in CT

Answer 13

No posterior acoustic shadow

Punctate hyperechoic lesions occupying the renal parenchyma
Without posterior acoustic shadow
