Nephritis hematuria is persistent or intermittent.

Nephritis hematuria is persistent or intermittent, mainly depends on the specific cause and severity of the disease, the following are some possible cases: 1. Persistent hematuria: chronic nephritis: such as IgA nephropathy, mesangial proliferative glomerulonephritis, etc., hematuria can exist for a long time, sometimes mild and sometimes severe. Other glomerular diseases: Such as membranous nephropathy, focal segmental glomerulosclerosis, etc., may also appear persistent hematuria. Systemic diseases involving the kidneys: such as systemic lupus erythematosus, allergic purpura, etc., can lead to glomerular inflammation, persistent hematuria. 2. Intermittent hematuria: urinary system infection: such as acute cystitis, urethritis, etc., hematuria can disappear after infection control. Urinary system stones: Hematuria may occur intermittently when stones are active. Hematuria may be relieved after stones are expelled. Urinary system tumors: bladder cancer, kidney cancer, etc. Other causes: strenuous exercise, nutcracker syndrome, etc. may also cause intermittent hematuria. It should be noted that hematuria may also be caused by other conditions, such as drug side effects, autoimmune diseases, etc. For patients with hematuria, they should seek medical attention in time for detailed examination.(such as urine examination, ultrasound, CT, etc.) to clarify the cause and take corresponding treatment measures. In addition, for children and the elderly, the cause and treatment of hematuria may be different. Children may be associated with urinary system abnormalities, infections, etc., requiring further examination and treatment. Elderly hematuria should pay special attention to the possibility of tumors, especially painless hematuria. In short, the characteristics of nephritis hematuria vary from person to person, and comprehensive judgment and treatment are needed according to specific conditions. Patients should follow the doctor's advice, conduct standardized examinations and treatment, and pay attention to rest, diet, etc. to promote recovery.
