Life Expectancy of Stage 5 Kidney Failure on Dialysis

Dialysis is still a main replacement therapy for the patients with stage 5 Kidney Failure at present. However, it can not improve the renal function at all. During dialysis, the renal function still keeps declining. Moreover, the patients have to deal with a series of complications during dialysis. For such many unpredictable factors in dialysis, the patients with stage 5 Kidney Failure are very worry about their life expectancy so much.
In fact, dialysis only can take a part of the function of the native kidneys. It can clear up the macromolecular and moderate molecular metabolic toxins. However, the micromolecule toxins still remain in the blood which can cause further damage to residual kidneys. Moreover, dialysis does not have secretion or regulation functions as the native kidneys. If the dialysis machine is performed improperly, the patients are very susceptible to develop blood pressure fluctuation, vascular disease etc. In severe case, the complication may cause the sudden death for the patients on dialysis. In rare case, the patients can live as long as 10 years and even longer on dialysis. Therefore, it is impossible to predict the life expectancy of the patients with stage 5 Kidney Failure on dialysis.
To extend the life expectancy of the patient with stage 5 Kidney Failure on dialysis, they should take effective treatment to improve the function of their native kidneys.
Of course, it is difficult to recover the normal renal function completely. However, if their renal function can increase to 15 and higher, it is quite possible for them to extend the dialysis intervals and even get rid of dialysis. If their native kidneys can finish the work of filtering blood and discharging metabolic products, the patients will certainly be able to live a normal life. In that case, the life expectancy of the patients with stage 5 Renal Failure will be extended enormously.
