Stone Surgery
ESWL (Shock Wave Lithotripsy)
A non-invasive treatment that uses focused shock waves from outside the body to break kidney or ureteric stones into small fragments.
01What is it?
ESWL delivers shock waves through the skin to fragment stones so they can pass naturally in the urine.
02When is treatment considered?
Suitable for selected smaller stones, usually in the kidney or upper ureter, that are visible on imaging and in a favourable position.
03Available treatment options
Alternatives include ureteroscopy (URSL/RIRS), PCNL for larger stones, or observation.
04What does the procedure involve?
No incision or scope is needed. The session lasts about 30–60 minutes with the patient lying on the lithotripter table; sedation or analgesia may be used.
05Expected recovery
Outpatient procedure. Fragments pass over days to weeks, sometimes with mild colicky pain or blood in urine.
06Common risks
Blood in urine, bruising, colic as fragments pass, incomplete clearance needing repeat sessions, and infection (uncommon).
07When to seek medical attention
Fever, persistent severe pain or vomiting after ESWL should be reported.
