Thanks for your query.
Main thing found here are presence of pus cells and calcium oxalate crystals
can be found usually which indicate contamination. But pus cell presence indicate urinary tract
inflammation mainly due to infection. As your daughter has abdominal pain
also, I would suggest you to consult physician and get it treated.
Oxalate crystals though suggestive of kidney stone, do not always indicate the same. !0-15% of time , it can be present in normal individuals also.
If you are more concerned about crystals , I would recommend you to get ultrasound
done to rule out same.
Ask her to eat a diet composed of low-oxalate foods like apple juice, cola, chicken, beef, bananas, melons, mushrooms, peas and ketchup.
I hope I have answered your query. Revert back in case you need further clarification.
