LYMPHATIC DRAINAGE OF URINARY BLADDER

 

The lymphatic vessels of the bladder run in three groups

Trigone vessels

Vessels from the superior surface pass to the posterolateral angle

Vessels from the inferolateral surfaces enter the superior surface.

All drain into the external iliac nodes. From these nodes they drain into the lateral aortic nodes. From the nodes, efferents issue to the lumbar lymph trunk. The lumbar lymph trunks help to form the abdominal confluence of lymph ducts or the cisterna chyli. Cistern chyli drains into thoracic duct.
