Chronic nephritis patients can live almost 20 years. Chronic nephritis is a disease with a very big disadvantage, once you get it can not be cured, sooner or later you have to develop into a uremic syndrome. It takes about 10 years from the time you get nephritis to the time you develop uremia, and about 10 years from the time you get uremia regular hemodialysis to the time you die. The combined time is about 20 years, but if you take regular kidney supplement medications after getting nephritis, such as dipyridamole, Bering capsules, and valsartan capsules, you can postpone the time to uremia by about 5 years. When uremia regular hemodialysis, you can choose compound blood purification methods, such as hemodialysis plus hemoperfusion plus hemofiltration, for more adequate removal of toxins, which can postpone the time of death further, and the survival time of patients will be much longer. Of course, if kidney transplantation is available, the survival time of patients may be longer.
