Renal calculi is a common disease in the urinary system. For patients with renal calculi, acute attacks may often occur. Once acute attacks occur, patients should be treated in regular hospitals in a timely manner. Generally speaking, when an acute attack occurs, it may be because a relatively small kidney stone falls into the ureter and forms an acute obstruction, which leads to an attack. At this time, it may be appropriate to use some pain relievers, as well as drugs to relieve ureteral spasm. The effect is better and the patient's condition can be quickly relieved. Of course, if acute infection is caused by kidney stones, it may lead to chills, fever, and sometimes high fever. It needs to use antipyretic drugs and antibiotics in time.
