Dr. Alan Greene on Sterile Pyuria

My 6-year-old has white blood cells in her urine.


My 6-year-old has white blood cells in her urine but with nothing growing on the culture. Her pediatrician is concerned. Do you know what could cause this?


The condition of having white blood cells in the urine with no bacteria growing on the culture is called sterile pyuria, which just means white blood cells in the absence of infection or proven infection. It might be only a passing thing or it can be a sign of kidney disease, tuberculosis, lupus, or a variety of different drugs that can cause this.

Your pediatrician is right not to ignore this. It is something that should be evaluated to look for the cause.
