I have a 1.5 cm stone in my kidney with no pain. I am scheduled for lithotripsy on 1/27/04 and again on 2/26/04. They will leave the stent in after both treatments. Has anyone had this experience? After reading the boards it seems like one treatment and the stent is out in a week. I had a stone in 99 and they left the stent in for 3 weeks. Same doctor.
