How Long Can You Live with Kidney DiseaseBefore we discuss this topic, let's review the index of glomerular filtration rate (GFR). This figure refers to the volume of raw urine that the two kidneys filter out of the blood in about one minute, with a normal rate of about 125 ml/min.

When it is lower than 90 ml/min, it means kidney function is impaired, and kidney disease goes from stage 1 to stage 2, and creatinine may begin to increase.

If it is lower than 15ml, it is stage 5, and your urine volume will reduce, and creatinine will be over 707 umol/L.

Knowing your own GFR, you can calculate the time to reach uremia based on the decrease rate of GFR each year.

Average time on dialysis

According to historical data, before the year of 2000, the time of uremia patients from dialysis to death was mostly 5-10 years. After entering the new century, with the progress of dialysis technology, the improvement of people's living standards and the improvement of medical system, most patients with uremia can be dialysis for 10-20 years.

The general trend is that the average length of dialysis is increasing year by year. And it will be over 20 years as the time going.

In other words, even with uremia, today's dialysis patients live longer.

The decrease rate of GFR

In 2008, a Japanese study looked at a decrease in GFR of about 0.5 per year in the early stages of renal insufficiency. It is not much different from normal people (0.36).

More to the point, GFR is also going down as people enter middle age, and as they get older, they are going to have kidney failure.

In the advanced stage or when GFR is below 40, the decrease rate begins to accelerate, reaching a decline of 3-4ml per year when approaching uremia.

This is the average progression rate of most primary chronic kidney diseases (such as IgA Nephropathy, Membranous Nephropathy, etc.), while the decrease of GFR in Diabetic Nephropathy is relatively rapid.

How long can you live with kidney disease?

The following is the primary kidney disease, Diabetic Nephropathy, Lupus Nephritis and other secondary kidney diseases needs to be considered separately.

1. Young people in their 20s or 30s with kidney disease

-If it is chronic nephritis or Nephrotic Syndrome, renal function is normal, GFR is higher than 90, in terms of the annual decrease of 0.5, uremia (filtration rate of 15) is still far away. As long as you receive standard treatment, there is basically no need to worry about uremia.

-If you are already in renal insufficiency stage (e.g., stage 2 CKD), with a GFR of over 60, uremia can be avoided if renal function is well protected.

-If renal failure is severe, by the end of CKD stage 3, and GFR is below 40, renal function declines more rapidly, progressing to uremia 5 to 10 years later. Dialysis takes about 20 years, so you can reach the age of 60-70.

2. Middle-aged kidney patients in their 40s

If the GFR (renal function) is normal or slightly decreased, standard treatment can keep you away from uremia.

If you have severe renal failure, you will be 50 years old by the time you get to uremia 5 to 10 years later; and dialysis can prolong your life to another 20 years.

3. Patients who have already entered uremia/are about to enter uremia

At present, the dialysis time of uremia patients in China is 10-20 years, and the average life expectancy is about 65 years. But this is just average data. As long as you improve dialysis mode, diet, and pace of life, you can live longer.

There are many kinds of blood purification, and hemodialysis is just a basic way to survive. For example, patients can do a hemofiltration at regular intervals, or continuous blood purification, or blood perfusion, plasma exchange, or consult with your doctor for more advanced blood purification. The improvement of blood purification technology promotes the continuous improvement of patients' life span, and we patients should make full use of it.

Brief summary

In fact, it's not just uremia patients that have room for improvement in their life span. Any kidney patient has room for improvement in their life span and can break the average line so that they can live as long as normal people. Therefore, there is no need to worry about your lifespan any more.
