Case #1 -
A 32 year old with severe right sided abdominal pain

DISCUSSION QUESTIONS:
4.) What is the pathophysiology that produces the pain in ureterolithiasis?

The pain is due to some degree of ureteral obstruction and distension of the ureter or renal pelvis. The severity of the pain is related to the rapidity with which distension develops rather than the degree of distension.
