The ureter is the tubule that takes the urine from the kidney to the urinary bladder. It is uncommonly afflicted by pathology that the pathologist sees on a day-to-day basis.

Normal ureter

Microscopic

Features:[1]

  • Mucosa - epithelium and fibrous tissue.
  • Muscularis:
    • Upper 2/3: inner longitudinal, outer circular.
    • Lower 1/3: inner longitudinal, middle circular, outer longitudinal.

Note:

  • There is no submucosa!

  • Ureter - cross-section. (WC)
