...so I now have a stent in my kidney and on the second surgery the doctor broke up the big stone.
A retrograde pyelogram? Ouch. I do fluoroscopy for those cases over in surgery. Fortunately, I only get to see the insides of your ureter on the viewer.
Once, I saw a doctor break up a stone so massive, it actually looked like a planetoid. We were all shocked in the surgery suite.
Good luck to you out there.
