Kidney Dialysis Life Expectancy: Life Span Of Dialysis Patients

In patients with renal failure, when conservative treatment fails to sustain quality of life, kidney dialysis is expected to improve it to a great extent. In connection to this it is imperative to know life expectancy after starting kidney dialysis.

Dialysis Treatment For Kidney Failure

Kidney dialysis is artificial replacement of kidney function, in case of renal failure; it can be acute or chronic renal failure.

In case of acute renal failure, which is reversible, dialysis is necessary till the renal functions improve.

While in chronic kidney failure the patient cannot expect complete recovery unless his kidney is replaced surgically, or alternately he is kept on maintenance dialysis till the period of his survival which may not be more than few years.

Kidney Dialysis Life Expectancy

The normal life span of a person suffering from chronic kidney disease is generally 5 years when he is on kidney dialysis.

Regular dialysis is started only in persons having end stage renal disease, whose creatinine and urea level in the blood remains persistently high than the normal parameters, with symptoms of less urine output.

Indications for dialysis: in chronic renal failure when creatinine clearance < 8 ml/min, pH< 7.2, potassium > 6 mEq/l

Life Span Of Dialysis Patients

The mortality rate of persons undergoing kidney dialysis for end stage renal disease is 22% in a year; this means survival rate beyond 5 years is difficult.

When a person undergoes dialysis, it is his conscious decision, because without it his survival will be in jeopardy even for few days as a result of accumulation of body toxins in the blood which cannot be removed due to kidney failure.

Generally it is observed that long term survival of patients on dialysis depends on adequacy of the dialysis process, patients who undergo shorter or irregular dialysis remain under dialyzed and malnourished have bad prognosis.
