Syndromes

  • Dribbling or leakage of urine, most often after urinating
  • Eat only hot, freshly cooked food
  • DO NOT drink water from streams or wells that are not treated. Only drink water that has been treated or chlorinated.
  • Include your child in the decision-making process, such as the time of day or the body site where the procedure is performed (this depends on the type of procedure being performed).
  • Hepatobiliary iminodiacetic acid (HIDA) scan, also called cholescintigraphy, to help determine whether the bile ducts and gallbladder are working properly
  • Diarrhea (watery, and often in large amounts)
  • Urinalysis
