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)
Pathology of the ureter - overview
- Kidney stones.
- Ureteritis cystica.
- Urothelial neoplasias, esp. in Lynch syndrome[2] - see urothelium.
- Malakoplakia.
- Others.
Specific conditions
Ureteritis cystica
General
- Similar cystitis cystica.
- Uncommon.
- Painful.[3]
- Related to von Brunn's nests.[4]
Gross
- Smooth/round projections into the lumen.

Microscopic
Features:
- Nests of urothelium within the lamina propria with cyst formation, i.e. lumens are present.
