Initial Series of Four-Arm Robotic Completely Intracorporeal Ileal Ureter

摘要

Ileal ureter formation has been found to be a suitable treatment option for long, chronic ureteral strictures not amendable to less invasive forms of repair. Minimally invasive surgical techniques for this condition have been investigated. We report the first series of robotic completely intracorporeal ileal ureter using a four-arm robotic technique. Three patients underwent this procedure, including one patient with a solitary kidney. All procedures were performed effectively with a median operative time of 450 minutes (range: 420-540) and median estimated blood loss of 100 mL (range: 50-200). Postoperatively, one patient suffered volvulus and subsequent necrosis of small bowel and ileal ureter, which required re-operation and small bowel resection, including the ileal ureter. The other two patients report no surgical complications to date. This early series represents preliminary technical procedure feasibility. Further experience is necessary.
