Whether the phenomenon of nephritis with no red blood cells in urine routine is improved mainly depends on the cause of red blood cells in urine. If the red blood cells are caused by nephritis, when there are no red blood cells in urine routine, it is considered that nephritis may be improved; however, some nephritis does not appear hematuria, while combined with urinary tract infection or stones and so on leading to the appearance of red blood cells in urine routine, if the red blood cells disappeared from urine routine, it does not mean that nephritis is improved. Most patients with nephritis may show hematuria, proteinuria, hypertension, edema, etc., and red blood cells can be seen in urine routine, after active treatment, red blood cells disappear in urine routine, then nephritis can be considered to be improved. Some patients with nephritis may show a lot of proteinuria, without hematuria, if combined with urinary tract infection or stone, can also lead to red blood cells in the urine routine, when the active anti-infection or lithotripsy treatment, urinary tract infection or stone symptoms are relieved, at this time, the red blood cells in the urine routine may disappear, but it does not mean that nephritis is better. Patients with nephritis are advised to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
