After extracorporeal shock wave lithotripsy, intravenous infusion is generally not needed, only appropriate drinking and urination can be done, but if the infection has been combined before extracorporeal shock wave lithotripsy, it is recommended to control the infection before lithotripsy, or to continue the intravenous infusion of anti-infective drugs after lithotripsy to prevent the spread of infection after lithotripsy and cause the phenomenon of elevated body temperature. In principle, extracorporeal shock wave lithotripsy treatment only requires oral lithotripsy medication, supplemented by a certain amount of exercise or oral pain medication, and intravenous infusion of glucose and saline, mainly to increase blood volume, so that the patient can produce more urine volume to promote the excretion of stones as soon as possible. For patients with nausea, vomiting and inability to drink, intravenous infusion of saline or glucose is used to increase urine volume and promote the discharge of stones as soon as possible.
