Hi,
Based on what you have posted, you daughter experienced this "leaking episodes" since she was two years of age 9 is this correct)?
Was any baseline scan done? An abdominal CT scan or ultrasound done during the onset of her symptoms?
Was there any associated fever, nausea, vomiting or rash when this first happened or in any instance afterwards?
With a significant history of having been born prematurely, I do feel that her birth history may be contributing to her current condition. An underlying infection and an underlying structural cause have to be ruled out. I suggest that a baseline abdominal scan be done to visualize the kidney, ureter and bladder. A urinalysis with urine culture may also be done to help rule out an infection.
Is there any way that you can discuss your daughter’s situation with your primary physician so she may be guided accordingly (especially with the insurance issues)? I believe she needs further evaluation.
The back pain could possibly be Kidney Stones.
