Crushing is carried out when the size of stones is in the range of 2-15 (20) mm (depending on the specific method), and if they are dense or crystalline, and also fixed in the tissues of the kidney structures (which causes various symptoms, up to renal colic).
When stones are quite large (more than 2 cm) or in a location that does not allow effective lithotripsy, a technique called percutaneous stone removal may be used.
