Uremia creatinine index

Nowadays, uremia has inevitably become a serious disease that destroys countless families. Because of the extremely terrible symptoms of uremia, many patients are particularly afraid and dare not face it. This has led to a wrong perception. When the creatinine measured in uremia exceeds 707μmol/L, some patients believe that they have uremia and that they cannot avoid lifelong dialysis. So, what is the creatinine index for uremia?

However, there are also patients in clinical practice whose creatinine levels are over 500μmol/L, and they are told by doctors: You need to undergo dialysis. Since creatinine alone cannot be used to determine whether a person has uremia, how can kidney disease patients know whether their condition has worsened?

In fact, as long as these two indicators are normal, there is no need to worry about deterioration regardless of the creatinine value.

1. Urine volume

Doctors say that for patients with kidney disease: as long as there is urine, there is hope, so oliguria or anuria is one of the important indicators of the uremia stage.

Generally speaking, the daily urine volume of a normal person is 2000-3000ml. So how do we determine oliguria or anuria? If the urine volume in a day (24 hours) is less than 400 ml, it is oliguria; if it is less than 100 ml, it is anuria.

In clinical practice, there are indeed some patients who only look at the creatinine value. When they see that it is greater than 700, they start to panic. Even though their urine volume is normal, they are still shocked and think that they are in the uremia stage.

In fact, normal urine volume indicates that the functions of renal tubular reabsorption and glomerular filtration have not been seriously damaged, so normal urine function can be produced and patients do not need to worry.

2. Kidney size

Most patients will ignore the size of the kidneys because they focus on the light spots and echo-free areas. In fact, it cannot be said that this approach is wrong, but it is not entirely correct.

In fact, the size of the kidneys is of great reference value for judging uremia. Changes in the kidneys reflect kidney lesions.

If uremia occurs, 80% of the renal units of kidney disease patients will atrophy and become necrotic, so their volume will be severely reduced. Therefore, even if the creatinine level is over a thousand but the kidney volume is normal, there is nothing to worry about. It may be a temporary abnormality caused by infection, high blood pressure, medication, etc.

So, what should I do if the above two indicators are normal but the creatinine is over a thousand?

Since it is not uremia, there is no need for the patient to be so anxious, which means that the current kidney unit can still meet most of the body's needs. Doctors believe that in this case, lowering creatinine is not important. The key is to find out the real reason for the increase in blood creatinine and eliminate it to prevent future problems and protect the kidney units!

If the patient chooses dialysis, although it can quickly lower the creatinine index, it will also damage the remaining kidney units. The situation that "the kidneys will atrophy" or "you will lose urine" will occur. This is a terrible situation. You didn't have uremia originally, but you got it because of your rash behavior. All I can say is: what a pity.
