My daughter of age 5 has had regular re-occurrence of yeast and/or UTI s. We had a ultrasound about 6 months ago and everything was fine however, she is still showing signs of discomfort. Constant itching and rubbing, holding in pee, constipation. My doctor has suggested a test, where they insert dye into the urinary track, to see if where the urine is travelling. Looking for more information on this test and other possible issues based on her symptoms
