What to do if i had kidney stones blasted, but the powder and small stones continue to be stuck in the kidney why?

Stone composition: Some patients' stones won't break during lithotripsy. Some stone substances are too hard to be broken by the shock waves. At this point, other surgical options may be considered. Continue to stay hydrated and avoid foods that cause the type of stone you have. Small stones may not cause a problem unless you are feeling them or having problem with your urine.
