Lymphatics of the urinary organs (English)

Retroperitoneal compartment exposed, showing the urinary system (kidneys, ureters and urinary bladder), and the major abdominal and pelvic vessels. The main groups of pelvic lymph nodes of the pelvis and posterior abdominal wall can be seen. Lymph from the paravesical, common, internal and external lymph nodes ultimately converge to the lumbar lymph nodes. Those in turn drain to the left and right lumbar lymph trunks, which along with the intestinal lymph trunk converge to form the cisterna chyli.
