Protein and blood in my 11yr old urine
by jojojc, Mar 09, 2004 12:00AM
My 11yr old daughter went in for a well check-up, +2 amount of protein showed up along with blood in her urine along with crystals, i was also told her urine was very concentrated. We redid the urine test protein +1 this time and blood showed again. No bacteria grew. She has had a history since 2yrs of age of bladder infections on and off. What does this mean and how concerned should i be? My doctor just asked for a first morning urine, so we are retesting her again. She has also been checked for reflux which came out negative. One time about 2yrs ago she had blood in her urine that you could see, but that went away with medicine.
Does this look like it could be a problem with her kidneys not filtering properly?
Thank you

Protein and blood in the urine are caused by a variety of diseases.
Gross hematuria (i.e. gross blood in the urine) is most frequently observed with urinary tract infection (UTI), irritation of the meatus or perineum, trauma, nephrolithiasis (including hypercalciuria without stones), sickle cell disease/trait, post-infectious glomerulonephritis, IgA nephropathy, and others.
Many of the causes of gross hematuria are also associated with microscopic hematuria (i.e. blood that cannot be seen with the naked eye). The most common causes of persistent microscopic hematuria in children include glomerulopathies, such as IgA nephropathy and glomerular basement membrane diseases (mainly Alport syndrome or thin basement membrane disease), hypercalciuria and microlithiasis, and UTI.
The presence of protein is also associated with the aforementioned diseases as well. I would suggest a referral to a kidney specialist, where tests can be done to image the kidneys as well as to quantify the exact amount of protein found. These would be initial steps to evaluate the diseases mentioned.
Followup with your personal physician is essential.
