Abstract

INTRODUCTION: Although several clinical guidelines for prostate cancer (PC) recommend extended pelvic lymph node dissection (ePLND) during radical prostatectomy for high-risk cases, there are several issues to consider, including certain technical aspects. A simplified approach to the medial internal iliac region and paravesical arteries has not been established. The uretero-hypogastric nerve fascia (UHF) envelopes the ureter, hypogastric nerve, and pelvic autonomic nerves. To preserve the UHF, it is possible to approach the medial side of the internal iliac vessels without injuring any important tissue. We analyzed technical feasibility and lymph node (LN) yields.
