Honestly, I don't believe that there is any way to prepare for a VCUG. They are extremely invasive & uncomfortable. My daughter has had 2 VCUG's & they are not fun to say the least. Unfortunately, it is a necessary test to diagnose urinary reflux & to determine the grade of reflux. I am opposed to my daughter taking a long term antibiotic to prevent reflux. I feel that the side effects are just too great and studies show that children that use antibiotics to prevent UTI's only lessen the chance of a UTI by 13%. My daughter takes probiotics (as you've mentioned) & also D-mannose. I usually buy her D-mannose on amazon. It is a natural sugar that e-coli binds to in the body & then is passed out through urine. E-coli is the main cause of UTI'S? Good luck & make sure daddy is ready to hold her hand during the VCUG & ready to spend the rest of the day spoiling the heck out of her b/c she deserves it! Also, urination may be painful once or twice after the test so don't push it. My 4 yr old actually had an accident in the middle of the Disney store b/c she was afraid to use the restroom due to pain. I told her to finish up in the middle of the aisle & discretely asked a worker for something to clean up the mess, bought a new outfit, changed in the dressing room & she was good to go!
