I have persistant kidney stones, lots of them, I have had 8 ESWL procedures over the past 9 months, at first the stones were passing like 5-6 small ones would be released each time i went pee for for the first 2 weeks after each proceedure. About every 6 weeks I have the stints (bi-laderal) removed and replaced and have the ESWL proceedure. The stones dont seem to be breaking up as well any more and still my KUB shows more replacing the ones that have passed. The stones are in both left & right kidneys and are rather large, without the stints the pain can be unbareable. what can I do.
