Lithotripsy is a procedure that is usually carried out in hospital. It uses high-energy shock waves to disintegrate stones in the kidneys, ureters, or bladder. The fragmented stones will then be passed in the urine, avoiding the need for surgery. Painkillers are given before the procedure since there may be some discomfort; children are usually given a general anaesthetic. For a few days after lithotripsy, you may have blood in your urine, and the treated area will feel bruised and tender. However, serious complications are uncommon.
