Q | can everyone have lithotripsy?

A | Patients taking warfarin should not have lithotripsy as they have an increased risk of bleeding after such treatment.

Some stones are not amenable to treatment due to their position within the kidney or urinary tract. This will be discussed with you by your specialist prior to any treatment.

If you have a cardiac pacemaker, you will need evaluation by your cardiologist before lithotripsy can be given. This is because the shock wave generator may interfere with the function of your pacemaker.

If you are morbidly obese (over 120 kg), lithotripsy is not advised due to low success rates and safety issues involving weight restrictions of the lithotripter.

Other patients not suitable for lithotripsy include pregnant women, patients with uncorrectable bleeding disorders and patients with a known abdominal aortic aneurysm.
