Pediatric Megaureter

Key Points About Megaureter in Children

  • A megaureter is a ureter that is much wider than normal. A ureter that is wider than 3/8 inch is a megaureter.
  • It occurs when a baby is growing in the uterus.
  • Often it is diagnosed by ultrasound while a woman is still pregnant. Or your child may also have imaging tests to look at the urinary tract.
  • It may not drain urine normally. Urine may back up into the kidneys. This can lead to infections and kidney damage.
  • Your child may need to take antibiotics to prevent urinary tract infections. In some cases, the megaureter will go back to normal on its own over time. If there is a blockage of the urinary tract, your child may need surgery.
