Fighting kidney stones is usually done by extracorporeal shock wave lithotripsy. Extracorporeal shock wave lithotripsy is mainly done by releasing shock waves from an extracorporeal lithotripter, which focuses on the stones in the kidney and then breaks the stones by releasing energy intermittently, and finally the stones are excreted from the body with urine. The time required for extracorporeal shock wave lithotripsy is usually about half an hour, but it may vary depending on the location of the stone or the size of the stone. For stones less than 1cm, you can try to remove the stones by exercise or by taking stone removal pellets. Patients with more than 1cm or less than 2cm need to have kidney stones.
