      ON THE ANATOMY OF THE RENAL LYMPHATICS (Abstract): The lumbar lymph nodes (LNs) serve as primary filter stations for the suprarenal gland, kidney and ureter and so, these ganglia may be positive for metastases of renal cell carcinoma when, according to certain surgical strategies, lymphadenectomy may be performed. There are few resources detailing the anatomy of the renal lymphatics that is usually overlooked. We aimed to investigate the detailed anatomy of the lymphatic extrarenal drainage of the kidneys by dissection and to get, based on evidences and references, an anatomic map of the lymphatic paths and stations specifically related with each kidney. We performed microdissections on blocks of kidneys and great abdominal vessels, dissected out in seven human adult cadavers. The evidences we obtained leaded us to a general pattern of the extrarenal lymphatic drainage that is accomplished via lymphatic collectors/plexuses of the renal pedicles, anterior and posterior on the left side, anterior, posterior and middle on the right side, as referred to their course on the anterior side, posterior side or, respectively within the renal pedicle. The main relay stations are the postcaval and postaortic lumbar LNs that mainly but not exclusively drain to the thoracic duct. Specific locations of the lumbar LNs on each side, as related to the roots of the renal pedicles, are surgically relevant if regional lymphadenectomy is decided and performed.
