We prospectively collected clinical and pathological data from 233 consecutive patients undergoing RARP and ePLND (encompassing obturator, internal iliac, external iliac and common iliac nodes up to ureteral crossing) for intermediate-or high-risk clinically localized prostate cancer at our institution from November 2008 to October 2012.
Lymph node dissection during robotic-assisted laparoscopic prostatectomy: Comparison of lymph node yield and clinical outcomes when including common iliac nodes with standard template dissection.
The deep sacral and common iliac nodes
receive vessels from the rectum, uterus, vagina and bladder.
Less frequently were nodes pertaining to the internal iliac chain In a 60% of the cases the existence of medial common iliac nodes
was verified (group of the promontory) that not always are including in the lympbadenectomy.
2] Studer's group advocates dissection not only of the external and internal iliac nodes and obturator nodes, but also the common iliac nodes
up to the ureter.
The lymphatic drainage of the bladder is quite extensive and consists of the visceral lymphatic plexus in the bladder muscle wall, the intercalated lymph nodes in the perivesical fat, the pelvic collecting trunks, the regional pelvic nodes (external iliac, hypogastric and sacral) and the lymphatic trunks, which abut on the common iliac nodes
