To break a stone, this generally refers to extracorporeal shock wave lithotripsy. It costs about 1000 yuan to do an extracorporeal shock wave lithotripsy. The charges of a tertiary care hospital are more expensive compared to those of a secondary care hospital. Extracorporeal shock wave lithotripsy is generally suitable for stones larger than 6mm and stones smaller than 15mm. If the stones are smaller than 6mm, it is recommended to treat them with medication. The more commonly used medications include stone removal granules and urinary stone granules, which can promote the discharge of smaller stones. If the stones are larger than 15mm, extracorporeal shock wave lithotripsy is not suitable because the stones are larger and the effect of extracorporeal lithotripsy will not be too good. In addition, even with extracorporeal shock wave lithotripsy, it may take many times to break the stone. Extracorporeal shock wave lithotripsy is generally only suitable for stones larger than 6 mm and smaller than 15 mm. Doing extracorporeal shock wave lithotripsy within this range still has certain effect and it is recommended to review after 1-2 weeks.
