Low Back Pain with WBC`s in Urine (8yr)

07/06/2009

Question:

My daughter (8 yrs) has had for the 3rd time in 8 months low back pain accompained with malaise and WBC`s in urine. The 1st and 2nd time she felt better after 4-5 days of an antibiotic. This time the pain is staying after 7 days of an antibiotic. Each culture showed no growth. We saw a CNP at urology today and her ultasound showed no kidney stones with a possibly larger size kidney with some fluid in it. The CNP thought the back pain was muscle, but it has occured 3 times in 8 mos. Today her CBC showed WBC`s again. We are awaiting a KUB result. What do you think?

Answer:

If the sonogram was relatively normal, and the cultures were negative, then most probably the low back pain is unlikely to be related to the kidney. There are a few conditions that can cause WBCs to appear in the urine without infection, and she may need further testing. I would speak with your pediatrician about this aspect.
