Blood in 2year olds urine

Patient: Is it normal for a 2 year old female to have blood in her urine? She doesn’t have a UTI, the culture didn’t grow any bacteria but showed a moderate amount of blood. One doctor told me it was not normal and another said yes, it was normal. Please advise.

Symptoms: Urgency to urinate. Said back hurt only once. 2 years old so hard to get any details from her.
