At present, the possibility of cure for chronic nephritis is very small, but it is possible to control the condition, let the condition delay development, or even stagnation, let the condition not develop so as to achieve clinical cure, to observe the patient’s blood pressure, 24-hour urine protein condition, water electrolytes, kidney function changes. For patients with chronic nephritis, at present, if you can control the 24-hour urine protein below 0.3g, the blood pressure control is stable, the blood creatinine control is stable, it is the current clinical cure. If you can’t reach 0.3g/24 hours or less, try to reach 0.5g/24 hours or less, and the renal function can be stabilized in the long term.
