Overview
- Muscular tube
- Passes in retroperitoneal space
- 2 Parts
- Abdominal Portion
- Pelvic portion
- At this points it moves medially
- In the female this movment is through the broad ligament
- In the male it is through the mesoductus
- It ends of the dorsolateral surface of the bladder
- Within the lateral ligament of the bladder
Wall
- It has a mucous membrane
- It is formed from transitory epithelium
- Protects against urine
- Under that is a lamina propria
- Followed by a muscularis layer
- And finally on the outside an adventitia
Junction With the Bladder
- The ureter enters the bladder obliquely
- Runs between the muscular layers and mucosa
- This stops back flow when the bladder is full as increasing pressure in the bladder pushes the two layers together occluding the ends of the ureters.
- They open through 2 slits on a raised "hillock"
Movement of Urine
The movement of urine along the ureters is achieved by peristalsis which is powered by locally regulated smooth muscle. This maintains a low pressure in the renal pelvis.
Vascular Supply
- Renal pelivs and proximal ureter
- Renal artery
- Distal ureter
- Cranial vesicular artery and the vaginal (female) / prostatic (male)
Lymphatic Drainage
Lumbar lymph nodes
