Core Tip

Core Tip: There is a lack of studies comparing the efficacy of fascia-oriented and traditional vessel-oriented lateral lymph node dissection (LLND). To compare the effects of fascia- and vessel-oriented LLND regarding the short-term outcomes and prognosis, we conducted a retrospective cohort study based on seven years of data. We found that it is safe and feasible to perform fascia-oriented LLND. Compared with vessel-oriented LLND, fascia-oriented LLND allows the examination of more lateral lymph nodes and may better protect postoperative urinary and male sexual function.
