Chronic renal insufficiency stage II is not serious, but the prognosis is worse. Chronic renal insufficiency is divided into five stages, of which stage II refers to the glomerular filtration rate above 60mL/min. At this time, although the kidneys still have the ability of detoxification and drainage, and the creatinine is not very high, there will not be serious hyperkalemia leading to the death of the patient, and the impact on the body is relatively not very big, but the prognosis of this disease is very poor, that is to say, sooner or later, this disease has to develop into a serious degree. Once diagnosed as chronic renal insufficiency, it cannot be cured. No matter what kind of drugs are applied to maintain the kidneys, the kidney disease will keep moving forward and sooner or later it has to develop into uremia. For patients with chronic renal insufficiency stage 2, the first step is to control the underlying diseases and factors that cause aggravation of renal function to slow down the failure of renal function. Secondly, they should be psychologically prepared for hemodialysis. Of course, if there are conditions, it is better to find a suitable kidney source and perform kidney transplantation.
