Urinary tract infections can cause a low fever. Generally, urinary tract infections are commonly caused by bacterial or pathogenic infections that can release exotoxins into the bloodstream, which can lead to a fever. If the infection is not cured, the fever may persist and may be accompanied by lumbar pain, urethral tingling, frequent urination and significant incomplete urination. During the hospitalization period, it is easy to monitor the temperature change and understand the process of temperature change, and according to the temperature pattern, symptomatic medication can be administered, for example, antibiotics are used 2-3 times a day to strengthen anti-infection treatment, and the temperature can gradually return to normal after the infection is eradicated. For example, patients with diabetes can be treated with blood sugar stabilization during hospitalization, and patients with stones can be treated with lithotripsy or surgery during hospitalization to remove the cause of the infection so that the body temperature can return to normal as soon as possible.
