According to creatinine staging, stage I is the compensated stage; stage II is the decompensated stage, with values between 177 and 442 μmol/L. Whether this value range can be cured or not depends entirely on the patient’s underlying disease and complications. Generally removing the causative factors, its able to return to normal level. If the patient has been in chronic renal failure for many years, it is necessary to test the treatment of their primary disease and complications. If its a newly discovered renal failure, acute stage II state, remove the pre-renal factors, post-renal factors, the patient can be completely cured. Most of the pre-renal factors are caused by insufficient intake, for example, the most common are diarrhea, cold, sweating and insufficient intake, when pre-renal renal failure occurs, its treatment is specifically as follows: 1. Rehydration: Some patients use vasodilators, such as ACEI, ARB class or other drugs, which can affect renal perfusion and renal failure. After the removal of drugs, and then give the kidneys a certain amount of energy, such as infusion, the patient can fully recover; if this prerenal factor is lifted, even stage III can recover; 2, post-renal acute renal failure, such as patients with stones, tumors, or prostate hypertrophy and hyperplasia, etc., to remove the obstruction, urine drainage, the patient can fully recover; 3, chronic renal failure stage II depends on the patient’s original disease and underlying disease, the earlier the treatment the sooner the patient recovers. Diabetic nephropathy patients, generally creatinine more than 300μmol / L recovery is less likely, but there are patients with creatinine more than 400μmol / L, after a period of time after eating Chinese medicine recovery to 180μmol / L, but a complete cure is difficult. Therefore, it is recommended that patients be detected and treated early to avoid further kidney damage.
