No edema may also be chronic nephritis. Chronic nephritis is a group of diseases with clinical manifestations of hematuria, proteinuria, edema and hypertension. If there is no clinically significant edema, but there is hematuria, proteinuria and hypertension, it is also clinically diagnosed as chronic nephritis. If there is no clinically significant edema and hypertension, but there is hematuria and proteinuria, it is called occult nephritis, also called asymptomatic hematuria or and proteinuria. If you have chronic nephritis without edema, you need further tests, such as 24-hour urine protein quantification, kidney function, kidney ultrasound, and exclude relevant tests that cause secondary nephropathy, such as tumor markers, infection eight, serum protein electrophoresis, urine peri-protein, rheumatic complete set, immune complete set, and if necessary, kidney biopsy to determine the type of pathology, determine prognosis, and guide treatment. If you have chronic nephritis, you should have a low salt, low fat, high quality, low protein diet, control blood pressure and reduce proteinuria, and choose hormone and immune therapy according to the type of pathology. The most important thing is to avoid factors that aggravate kidney damage, such as infection, fatigue and the application of nephrotoxic drugs, chronic nephritis is prolonged, the disease progresses slowly, and eventually to chronic renal failure.
