As the second advanced stage of kidney disease, if CKD stage 5 can not be treated well, it will gradually develop CKD stage 5. Then how long it tales from CKD stage 4 to CKD stage 5? Well, the answer varies from case to case.

For some cases, CKD stage 4 gradually develops to CKD stage 5 with different speed for different cases, which is associated with many factors like the primary disease. A study conducted in USA says that about 85% of CKD patients GFR decreases yearly at the level from 0-12.6ml/min and the average level is 4ml/min. How much GFR decrease yearly is different in different primary disease. According to your GFR level and primary disease, a rough answer to how long it takes from CKD stage 4 to CKD stage 5 can be measured out.

However, for some other cases, CKD stage 4 can be reversed by an efficient treatment. Micro-Chinese Medicine Osmotherapy is commonly used in clinic nowadays to treat various of kidney disease. The reason why it becomes more and more popular is because it aims at repairing kidney damage and recovering renal function. This treatment is based on Chinese herbal medicines, but used externally. Kidney disease patients just need to lie on the bed to take this treatment. Two bags filled with processed Chinese herbal medicines are put under lower back of patients, the osmosis device helps active materials directly get to kidneys after permeating into skin. Foreign patients describe it as Chinese massage, very comfortable. Through a series of special function, the renal function is expected to be gradually recovered, in that case, CKD stage 4 will be reversed. Because the active materials need taking by blood flow to kidney lesions, the treatment effect may not be that obvious if kidney disease patients have had no urine output for a long period of time.
