Aortic/ Para aortic/lumbar/ Retroperitonial nodes are all saying the same thing as well.

from wiki:
Lymphatic drainage of the testes follows the testicular arteries back to the paraortic lymph nodes, while lymph from the scrotum drains to the inguinal lymph nodes.

While on the topic of lymph drainage. The basic concept here is that the vessels which supply an area determine its lymphatic drainage. As mentioned above, since the testes are drained by the testicular vessels which are directly from the aorta, and eventually drain IVC, the Lymph nodes will therefore be in this region. The scrotum however, though in such close proximity recieves its blood supply from the internal pudendal artery from the Internal Illiac. So the lymphatic drainage for the scortum is therefore also the nodes in this region.

By the same concept, the area directly below the pectinate line (line where developmental endoderm and ectodermal tissue meet in the rectum) will have lymphatic drainage to the superficial inquinal, while directly above the pectinate line, lymphatic drainage is to nodes aroudn Inferior mesenteric vessels. Just apply the same concept to any body part and it generally works. Granted, this would mean you need to know blood supplies of the parts in question.
