Most of the decline in kidney function due to acute kidney injury can be recovered. Most of the decline in renal function due to chronic kidney disease cannot be recovered.
The decline of renal function caused by acute renal injury, such as ischemia, renal perfusion insufficiency caused by renal anterior renal injury, obstruction and other causes of postrenal renal injury, after active treatment of the primary pathology, most of the patients’ renal function can be completely restored to normal.
The decline of renal function caused by chronic renal insufficiency is mainly due to glomerulosclerosis, and the sclerotic glomerulus cannot be completely recovered, so the renal function of this kind of patients cannot be completely recovered.
However, through active drug treatment, such as controlling blood pressure, lowering urinary protein, and actively treating the primary disease, most patients can slow down the decline of renal function, delay the time to enter uremia, or even not progress to uremia.
It is recommended that patients with impaired renal function should go to the hospital in time, complete the relevant examinations under the guidance of the doctor, and take active treatment to avoid the progression of the disease.
