The human body may develop fever after urinary lithotripsy surgery, which should be judged according to the specific degree of temperature increase. After surgery, there will be a transient increase in body temperature, which will not be greater than 38.5℃, mainly due to surgical anesthesia and medication, and a mild increase in body temperature caused by human stress, which is a manifestation of self-elevation of the body’s immunity and is a beneficial reaction to the human body. There is also an increase in inflammatory factors due to surgery, such as open surgery, or more blood flow, which causes changes in the human body, such as absorption of heat, but the temperature does not exceed 38.5℃. If the temperature is above 38.5℃ after surgery, it is possible that the kidney stone has local infection, and the pus will be discharged from the body through the urinary system, and there is a possibility of reflux into the blood during the process of stone fragmentation, causing fever.
