KUB

X-ray

KUB done after the CT to enable follow-up with abdominal X ray, clearly showing the stones in the left UVJ and the jackstone calculus.

Case Discussion

Incidental jackstone calculus in the urinary bladder, too large to pass into the urethra.
The culprits were the stones lodged in the left UVJ.
