Most of the renal function compensatory stage cannot be cured, and only a few of them can be cured. In the compensatory phase of renal function, the glomerular filtration rate decreases about 60-90 mL/min. The compensatory phase of chronic renal failure is mainly to delay the progression of renal function, protect the residual renal function and avoid the application of nephrotoxic drugs. During the compensatory phase of renal function, blood pressure should be controlled, proteinuria should be reduced, and antihypertensive drugs, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers that protect renal function and reduce proteinuria should be used, and attention should be paid to their side effects, dry cough, hyperkalemia, and decreased renal function. If hyperkalemia occurs, it needs to be discontinued immediately and treated with potassium lowering, kidney protection treatment can be given, Bailing Capsules, Haikun Kidney Hi Capsules, Urotoxic Clearing Granules. Once the symptoms of uremia appear, kidney replacement therapy, hemodialysis or peritoneal dialysis treatment should be carried out, and various complications of uremia should be actively treated.
