Case 81: Bilateral Ureteric Calculi Causing Obstructive Uropathy

 

Ultrasound Features:

- Bilaterally enlarged kidneys with echogenic parenchyma & moderate pelvicalyceal system dilatation.

- An echogenic structure casting acoustic shadow on grayscale & twinkling artifact on color Doppler, is noted at the right distal ureteric lumen causing proximal dilatation.

- Another echogenic structure casting acoustic shadow on grayscale & twinkling artifact on color Doppler, is noted at the left mid ureteric lumen causing proximal dilatation.


Ultrasound Diagnosis:

Bilateral obstructive uropathy due to right distal ureteric & left mid ureteric calculi causing bilateral moderate hydroureteronephrosis (Grade III)
