Generally, chronic kidney failure in China can be divided into 4 stages:
compensation stage of renal insufficiency, discompensation stage of renal
insufficiency, early stage of renal failure, advanced stage of renal failure,
the basis of which is the level of serum creatinine. The detailed information is
as follows:
In the compensation stage, serum creatinine is 133 to 177umol/L. In this
stage, patients generally have no symptoms, or they can only feel weakness,
soreness of the waist, and increased urine at night.
In the discompensation stage, serum creatinine is 186 to 442 umol/L. In this
stage, patients feel poor appetite, slight anemia and slight acidosis.
In the early stage of renal failure, serum creatinine is 450 to 707 umol/L.
In this stage, the above mentioned symptoms become more obvious.
In the advanced stage of renal failure, serum creatinine is more than 707
umol/L. In this stage, patients begin to have heart failure, high K, bleeding in
digestive tract, barriers in nervous centralis, and so on, which even threatens
patients’ life.
In addition, the stages of chronic kidney failure in China can also be
connected with the classification of CKD internationally, which is on the basis
of GFR (glomerular filtration rate).
Generally, the compensation stage equals the second stage of CKD.
The discompensation stage equals the third stage of CKD.
The early stage of renal failure equals the fourth stage of CKD.
The end stage of renal failure equals the fifth stage of CKD.
