Lymph nodes near the kidneys?

Prior to surgery (9/17/2013) and abdominal CT scan (9/9/2013)  I have been given the designation of a T2N0M0.  

How to they test to see if it has spread to lymph nodes?  Do they remove a few to test?  If so, where are they located?  I can't seem to find any on anatomic diagrams.  Will they light up on the CT scan tomorrow if positive?
