First reported port site metastasis after single-port robotic radical cystectomy.

Port-site metastasis (PSM) is a rare complication of laparoscopic and robotic assisted oncologic surgery. The da Vinci Single-Port (SP) platform (Intuitive Surgical, Inc., Sunnyvale, CA) is increasingly utilized for urologic procedures including radical cystectomy, and given the need for fewer port sites, this should theoretically confer a lower risk for PSM. Here we describe a 74-year-old female with high-grade urothelial carcinoma (HGUC) of the bladder who underwent single-port robotic-assisted radical cystectomy (SP-RARC) and developed a metachronous metastatic nodule at her port site incision. To our knowledge, this represents the first reported case of PSM after SP-RARC.
