Vesical vein

Vesical Veins

The vesical veins drain the urinary bladder.

The Vesical veins form a plexus, the vesical venous plexus, around the urinary bladder and drain into the internal iliac veins. They are part of the venous system and play a crucial role in the drainage of the urinary system.

Anatomy

The vesical veins originate from the vesical venous plexus, a network of small veins found on the surface of the urinary bladder. This plexus is formed by the union of several small veins that drain the bladder wall. The vesical veins then drain into the internal iliac veins, which eventually join the inferior vena cava to return blood to the heart.

Function

The primary function of the vesical veins is to drain deoxygenated blood from the urinary bladder. They also play a role in the regulation of bladder pressure, as they can constrict or dilate in response to changes in bladder volume.

Clinical significance

Abnormalities or damage to the vesical veins can lead to various medical conditions, such as hematuria (blood in the urine), bladder varices, and pelvic congestion syndrome. Therefore, understanding the anatomy and function of these veins is crucial for medical professionals in diagnosing and treating these conditions.
