Usually kidney failure with creatinine 170μmol/L represents moderate or severe reduction of kidney function, which is generally more serious. There are acute renal failure and chronic renal failure, no matter which kind of renal failure, creatinine 170μmol/L is a more serious situation and needs immediate treatment. The most important thing is to find out the cause of renal failure and treat the primary cause in order to alleviate the symptoms of renal failure fundamentally. 1. Acute renal failure: If the renal perfusion is insufficient due to diarrhea, bleeding, etc., causing creatinine elevation, it is necessary to supplement fluids, blood transfusion and other treatments in a timely manner; if it is due to the obstruction caused by urinary stones and tumors, it is necessary to release the obstruction in a timely manner. The creatinine increase caused by the above situations is more serious. If no effective treatment is taken, creatinine may increase progressively. 2. Chronic renal failure: If the creatinine 170μmol/L is caused by chronic nephritis, hypertensive nephropathy, diabetic nephropathy and other slow progress, it is necessary to actively lower the urinary protein (such as Benadryl, Prednisone Acetate), lowering blood pressure (such as Nifedipine Extended-Release Tablets), lowering glucose (Dagliflozin) and other treatments. These cases are more serious and generally cannot be cured, but only slow down the progress of the disease. Renal failure creatinine 170μmol / L, should immediately regular hospital medical treatment, under the guidance of the doctor for reasonable treatment, as soon as possible to alleviate the symptoms and reduce the adverse effects of the disease.
