[Application of pelvic sentinel lymph node tracing technique in radical prostatectomy]

Pelvic lymph node dissection is an important step in radical prostatectomy (RP). Extended pelvic lymph node dissection (ePLND), currently employed for patients with intermediate- or high-risk PCa, may lead to overtreatment, prolong the operation time, and increase the risks of complications. Sentinel lymph node (SLN) is defined as the first metastasis lymph node from the primary tumor. In addition, SLN distribution is essential for overall lymph node dissection. However, due to the complex and diverse lymphatic drainage pathways and the inaccuracy of lymphatic tracing technology, SLN distribution and dissection have always been controversial. This review focuses on the application of pelvic SLN tracing technique in radical prostatectomy.
