What is proteinuria?(Proteinuria and Kidney Disease)
For the normal people, there is nearly little protein in urine, but once the 24h amount of protein is more than 150mg, it can be called proteinuria.
If there are foams in urine which even are like the ones in breaking eggs, it is quite likely to be proteinuria. But it is also essential to take a further examination and ensure whether it is proteinuria. However, not all of the urine containing white foams can be named as proteinuria. Some patients' urine presents lots of foams, especially female, but there is no abnormality in Urine Routine Test. This situation is quite common. After being put aside for about 2 hours, the foams will disappear spontaneously. So the occurrence of foams in urine also has relationship with the shock.
Whether all of the proteinuria means our kidney is damaged?
Clinically, proteinuria can be physiological and pathological. The former one is not caused by the disease and mostly, it is transient. It is mainly seen in the following situations:
(1)Functional proteinuria: this kind of proteinuria is usually caused by various factors, like fever, strenuous exercise, a cold etc.. And usually, there is no organic disease in urinary Immunotherapy. Once these inducements are eliminated, proteinuria will disappear. This kind of proteinuria is lighter and in general, the 24h amount of proteinuria is less than 0.5g.
The pathological proteinuria is persistent and urine protein presents positive in many-times' tests. It is most commonly seen in glomerular disease.
(2) Orthostatic proteinuria or postural albuminuria. It usually occurs in adolescents. And the proteinuria will disappear during decubitus. Generally, there are no other abnormalities, like edema(Swelling and Kidney Disease), hematuresis, hypertension etc. The amount of proteinuria is less than 1g, so patients need no worry.
Whether proteinuria can influence our renal function or not?
The key to answer this question lies in how much there is proteinuria. If the amount of proteinuria is more than 1g persistently, then patient's renal function may have been damaged. If the amount of proteinuria is more than 3g continuously, patient should take the treatment positively or the renal function will be injured seriously. The continuous filtration of large quantity of proteinuria through glomeruli can lead to glomerular high filtration, high perfusion and high pressure, which can cause the glomerular sclerosis, and then the Renal Insufficiency will occur.
So when we find proteinuria, firstly, we should judge its nature and then take the relative treatment.
