The ureter is a smooth muscle-lined tube which connects the renal pelvis with the urinary bladder.

Disease of the ureter include:

- Ureteroliths
- Circumcaval ureter associated with portosystemic shunt[1]
- Ureteral atresia

These diseases commonly result in hydronephrosis, chronic renal disease and cystitis.
