What should you know about lithotripsy for kidney stones?

A clinician first considers the stone's size, position and whether urine is flowing freely. During treatment, focused shock waves are directed from outside the body towards the stone. The fragments may leave over the following days, and some people notice blood in the urine, cramping or discomfort as they pass. Lithotripsy is not suitable for every stone; blockage, infection, pregnancy or certain medicines may change the plan.

Ask how to take regular medicines before the appointment, especially blood-thinning medicines. Follow the team's instructions about eating, drinking and arranging transport if sedation is used. Afterward, drink fluids if your clinician says this is appropriate, use only recommended pain relief, and strain urine if asked so a fragment can be checked. A GP Consultation can help assess ongoing pain, while an Abdominal Ultrasound may be used to review the urinary system. Kidney Stones and Dehydration information can help with prevention advice.

Seek urgent medical care for fever or chills, worsening flank or abdominal pain, repeated vomiting, inability to pass urine, faintness, or feeling suddenly very unwell. A stone with infection or blocked urine needs prompt assessment. Contact your treating team if bleeding becomes heavy, pain is not controlled by the advised medicine, or expected fragments do not pass. Painful Urination and Difficulty Passing Urine are useful symptoms to describe clearly.

Ask where the stone is, why lithotripsy is recommended, what alternatives exist, which medicines need adjustment, how to collect fragments, and when follow-up imaging is planned.
