Q | are there any complications from lithotripsy?

A | When a stone is fragmented by lithotripsy, the fragments usually pass down the ureter into the bladder and then can be passed out in the urine.

If the fragments are too large, they can get stuck in the ureter and cause the symptoms of renal colic.

Occasionally, patients have a J-J Stent inserted prior to lithotripsy to prevent any blockages like this.

Occasionally stones can harbour infection and lithotripsy can release organisms into the urinary tract causing urinary or blood infections.

If there is any risk of this, the patient is usually given high dose strong antibiotics prior to the treatment and these are continued for a time afterwards.

This will be discussed with you at the time of treatment. If you feel unwell or develop a fever after a treatment, you should contact the urology department or your GP for urgent advice.
