Questions:

  1. Would you feel comfortable using POCUS as the only imaging test if it revealed hydronephrosis on the side of pain? Why or why not?
  2. Is probe orientation in the transverse view an essential component of this scan? Why or why not?
  3. Are you surprised that the 3 year old with a 1cm stone received no further imaging? Why or why not?
  4. In one of the papers, CT was avoided in all patients. In the other, it was obtained in all patients. Why the difference?
  5. Bonus question: Why are patients with IBD predisposed to urolithiasis?
