What is a cold, high fever, hematuria?

Cold generally refers to upper respiratory tract infection, high fever generally refers to high fever, upper respiratory tract infection, high fever, hematuria may be caused by urethritis, nephritis, kidney stones and other factors, the specific analysis is as follows: 1. Urethritis Urethritis can damage the urethral barrier, leading to local, capillary rupture, resulting in urine blood, followed by reduced body resistance, unable to resist pathogen invasion, affecting the function of the temperature regulation center, the occurrence of upper respiratory tract infection high fever phenomenon. 2. Nephritis can reduce glomerular filtration function, leading to hemoglobin leakage into urine, causing urine blood, but also inflammatory factors released into the blood, leading to acute inflammatory reaction in the body, will make the temperature regulation center abnormal, causing body temperature rise. If nephritis patients do not pay attention to nursing at ordinary times, the body will catch cold, leading to pathogenic bacteria invading the respiratory tract, causing upper respiratory tract infection. 3. Kidney stones After kidney stones occur, stones cut through kidney tissue, causing blood to enter the urethra, causing hematuria. If not treated in time, local inflammation and infection, leading to elevated body temperature, can cause fever. In addition, it will reduce the body immunity, leading to virus invasion, causing upper respiratory tract infection.
