The survival time of creatinine 700μmol/L is related to the general condition of the patient. If the patient’s general condition is good, he may not need dialysis after regular kidney preservation treatment, such as oral Jin Shui Bao, medicinal charcoal, Bai Ling capsule, Hai Kun kidney hi capsule, oral Chinese medicine or Chinese medicine enema to expel intestinal toxins, and use erythropoietin to improve the level of nephrogenic anemia in the body, most patients can defer dialysis for 3-5 years. If the patient has reached the dialysis level with obvious oliguria, anuria, electrolyte metabolism disorder and uncorrectable heart failure, it is also possible to dialyze for up to 20-30 years after regular dialysis and adequate dialysis, so it depends on the general condition of the patient. If the patient has been hypertensive for many years, and is malignant hypertension, and has the basis of cerebrovascular disease, cardiovascular and cerebrovascular accidents can occur at any time, so the length of survival of the patient cannot be judged based on the simple creatinine value, but should be integrated with the patient’s cardiac function, renal function and cerebrovascular condition.
