Editing Bladder (section)

== Lymphatic drainage ==

* '''The bulk of the lymphatic drainage passes to the external iliac lymph nodes.'''
* '''Some anterior and lateral drainage may go through the obturator and internal iliac nodes'''
* '''Portions of the bladder base and trigone may drain into the internal and common iliac groups.'''
* '''Limits of dissection for standard lymphadenectomy during radical cystectomy:'''
** '''Superior: ureter/bifurcation of the common iliac artery'''
** '''Inferior: circumflex iliac vein and Cloquet’s node/Cooper ligament at the femoral canal'''
** '''Lateral: genitofemoral nerve'''
** '''Medial: bladder and internal iliac artery'''
** '''Posterior: obturator nerve/fossa'''
