Over the past century, it has been recognized that pelvic and abdominal lymph nodes are common sites for metastatic prostate cancer (1). Flocks (2) reported that metastatic nodes were also frequently found in early prostatic cancer, this finding, associated with the development of safe surgical techniques to remove the prostate gland, has brought attention to the importance of pelvic lymphadenectomy. The presence of positive lymph nodes is associated with a worse prognosis and every effort should be made to detect the lymph node involvement and establish the best therapeutic plan. Important questions have arisen since then: how extensive should the pelvic lymph node dissection (PLND) be? is PLND a staging or therapeutic procedure?
