Lymph Vessels of the Ureter

The lymph vessels of the cranial part of the ureter drain to the lumbar aortic lymph nodes, those of the middle part drain to the medial iliac lymph node, and those of the caudal part drain to the hypogastric lymph nodes. The lymph vessels of the caudal part of the ureter merge into 1 to 2 vessels which accompany the ureter until it nears the urinary bladder before running in the lateral ligament of the urinary bladder and entering the hypogastric lymph nodes.
