Hi,
Lithotripsy is a procedure that attempts to break up the stone with minimal collateral damage by using an externally applied, focused, high-intensity acoustic(sound) pulse.
The passage of stone fragments may take a few days or a week and may cause mild pain.
Patients are instructed to drink as much water as is practical during this time.
A patient of the procedure has equated the after effects to "a punch to the kidney" (pain while urinating, with blood evident).

The pain maybe due to the fact that you are passing out the stone fragments.
You could take pain medications prescribed the doctor when the pain is severe.
