Robotic Intracorporeal Continent Cutaneous Diversion

Abstract

Robotic intracorporeal urinary diversion has mostly been done for ileal conduit or orthotopic neobladder diversion. We present what is to our knowledge the initial series, detailed technique and outcomes of the robotic intracorporeal Indiana pouch with a minimum 1-year followup. Ten patients underwent robotic radical cystectomy, pelvic lymphadenectomy and intracorporeal Indiana pouch urinary diversion for cancer in 9 and benign disease in 1. Data were collected prospectively. Baseline demographics, pathology data, and 1-year complication rates and functional outcomes were assessed. All 10 cases were successfully completed intracorporeally without open conversion. Median total operative time was 6 hours, including 3.5 hours for pouch creation. Median blood loss was 200 cc and median hospital stay was 10 days. Four Clavien grade 1-2 and 3 Clavien 3-5 complications occurred. None of the patients had a bowel leak. One noncompliant patient requested undiversion to an ileal conduit. The remaining 9 patients successfully catheterized the ileal channel and were completely continent at the last followup at a median of 13.7 months (range 12.3 to 15.2). Study limitations include small sample size and short followup. We present what is to our knowledge the initial series of robotic completely intracorporeal Indiana pouch diversion. Early perioperative data indicate acceptable operative efficiency and complication rates. Longer followup is required to assess the functional outcomes of this less commonly performed diversion.
