What Causes Pressure In The Abdomen Post Lithotripsy?

I feel like i have got to pee a lot all the time but can t pee but just a little. I can not stand for anything to hardly press against my lower abdomen because of the pressure. I have had kidney stones in the past month. One was a 10mm lodged in my urethra and the doctors went in and took it out. Two weeks later they did lithrotripsy on a stone that was in kidney that was huge but it did not crush the stone. But ever since I have been having this urge to use bathroom a lot and lots of pressure in the bottom.
