Megaureter is simply the medical term for a "large" or "big" ureter.

  • The ureter is a tube-like structure that serves as the passageway for the flow of urine from the kidney to the bladder.
  • There are two ureters, one for each kidney.
  • Together, the ureter and the kidney collecting system are referred to as the upper urinary tract.
