Hi,
I suppose that a urine culture has been done?
I suggest that a urine culture be done in the event that the UTI recurs.The urine culture will guide treatment.
Has your daughter been exposed to anyone with tuberculosis?
Is there any history of previous travel?
Any infections in infancy that could have led to any hospitalizations?
In children, a thorough assessment is required to rule out any anatomic or structural problems such as urine reflux to the ureters which I believe has been ruled out in your child's case.Also, the ultrasound did not show anything so a structural anomaly may have been excluded as well.It is also important to note that children who usually holds urination or who has difficulty voiding properly may have increased risk for UTI.
Does your daughter still wear diapers? If yes,I suggest that the diapers should not be allowed to stay in her body for long especially when wet. Change diapers frequently. Give her plenty of fluids everyday.Try to train her in voiding urine at specific times during the day.Keep this schedule regular so she can follow it and anticipate it.This may be beneficial.
Other more uncommon causes of recurrent UTI is an underlying immune disorder.You may discuss this with your child's physicians.
I understand your frustration.Treating UTI in the pediatric age group may be more complex than managing UTI among adults. Just take this one step at a time.Openly discuss with the physicians your concerns .
Do keep us posted.
I should add that when she has an infection the doctor will give her antibiotics and then 2 weeks later check her urine again and it will be clear but then a day or two later she will have signs of infection again and we will do more urine and it will show an infection
