Proteinuria is a condition in which the urine contains an unusually high amount of protein. Keep in mind that it is normal for some amount of protein to be present in the urine. Under normal circumstances the filtering units in the kidney clean up the blood and hold on to the protein in the blood so that it does not spill out into the urine. Proteinuria typically happens when the glomeruli (tiny filters in the kidneys that clean the blood) are damaged and allow too much protein to pass from the blood into the urine or when the tubules (the pipes that convert filtered blood into urine) lose protein.
Proteinuria can be classified into three kinds:
In its early stages, proteinuria has no signs or symptoms. Once the condition progresses, you may notice that your child's urine looks foamy. Your child may also experience edema (swelling of the hands, feet, abdomen or face caused by excess fluid in the body).
Doctors at Riley at IU Health perform the following tests and exams to diagnose proteinuria:
If your child is diagnosed with proteinuria, it is important that you work with your child's doctor to manage the condition so that it can be properly treated.
The treatment of proteinuria is dependent on the cause of proteinuria. Therefore, treatment varies and is different for every child. Early treatment of the condition will protect the kidneys from further damage and prevent kidney failure.
