Lithotripsy is like getting hit with a cannon ball in a bath tubDave, sorry you are having all these health issues. I had a bout of diverticulitis a year ago which went away quickly and hasn’t returned but in the process of being scanned for it they found a 2 cm kidney stone. I never knew it was there because it was not moving and never would but they recommended I have it removed. So, I did, but it took 2 surgeries, totaling 4 hours to pulverize it. Not a pleasant experience. In a side note, if you are on antibiotics for diverticulitis it is recommended you take a probiotic during that time and after to help restore the good bacteria in your gut. That’s what my GI had me do.
