Stones in the urinary tract can cause increased body temperature or fever. Stones in the urinary tract can cause different degrees of obstruction, which can lead to fever, such as prolonged hydronephrosis and pyelonephritis, which can lead to back pain or fever. If the stone stays for a long time and causes local mucous membrane to break down, urine invasion of the local mucous membrane can lead to infection, which can result in an increase in the number of white blood cells in the blood, an increase in body temperature, or an increase in pain. Some stones are formed due to infection, and symptoms such as elevated body temperature or frequent urination and urinary urgency can appear very early. It is recommended to go to the hospital for anti-infection treatment. Surgery, extracorporeal shock wave lithotripsy and other treatments are not recommended during the period of stone fever, so as not to cause the spread of infection difficult to control, resulting in patients with infectious shock and other manifestations.
