Robotic-assisted psoas hitch with ureteral reimplantation.

OBJECTIVE: To demonstrate a robotic-assisted psoas hitch with ureteral reimplantation.

METHODS: We gleaned video footage from a robotic-assisted psoas hitch procedure performed for a patient with an isolated pelvic recurrence of ovarian cancer.

RESULTS: We demonstrate trocar placement and a robotic-arm docking strategy for pelvic recurrence of ovarian cancer. We also show surgical steps involved in a psoas hitch and reimplantation of a transected ureter into the bladder. Special emphasis is placed on guiding the surgeon using key robotic instruments and materials to optimize the robotic completion of this procedure. Key components of the procedure, including en bloc tumor excision and ureteral transection, are shown. The bladder is placed on traction using the fourth arm, and the avascular planes of dissection, including the space of Retzius and the paravesical spaces, are shown. The bladder is then backfilled to allow the surgeon to determine the ideal placement of the ureteral reimplantation to ensure the anastomosis is tension free. The surgeon then demonstrates where and how to place anchoring sutures from the bladder to the psoas muscle. The ureter is examined to determine where it can be implanted in the bladder with zero tension or angulation, which would compromise function and healing. The ureter is prepared for reimplantation, including trimming, tagging, and spatulation. An instrument tie technique is used to implant the ureter into the bladder and a ureteral stent is placed. Robotic-assisted psoas hitch with ureteral reimplantation has been described in the literature.1-4 CONCLUSIONS: Through the use of still photographs and video, we demonstrate the technique of robotic-assisted psoas hitch with ureteral reimplantation.
