This is a simple non invasive technique by which stone is powdered inside the kidney. Our modern machine does not require general anesthesia as it produces, very little pain. Hence this is an outpatient procedure, not requiring admission.
A mechanical shock wave is generated under water and focused on the stone by special machines. The shock wave cause cracks to form in the stone. Urine gets in to these cracks and cause fragmentation. This fragmentation may take from 1 to 14 days.

Stones in the kidney and upper ureter less than about 1cm size and not obstructing the kidney completely, can often be treated by ESWL. Such stones can also be treated by other techniques such as RIRS – Retrograde Intra Renal Surgery. The advantage of ESWL, is that it avoids any wound on the skin, and is an outpatient procedure, not requiring anesthesia (in our hospital).
However there are a few disadvantages. The fragmented stones take a few days to clear from the urinary passage. During their transit the fragments may cause discomfort in spite of the medicines the doctor prescribes to prevent this. If the stone has not fragmented completely in the first session, further sessions will be required at 3 weekly intervals. ESWL is successful in 80% of cases. In 20%, when ESWL falls, RIRS is required.
RIRS
Under anaesthesia a 3 mm diameter flexible telescope is passed into the kidney via the Urethra (water passage from bladder) Bladder and up the Ureter (the tube connecting the bladder and Kidney). The stone in the kidney can then be fragmented using laser fibre passed through this flexible telescope called flexible Ureteroscope.
