Introduction: To describe a step-by-step technique for single-port transperineal intracorporeal ileal conduit urinary diversion using a purpose-built robotic platform.

Technical considerations: In one male cadaver, the da Vinci SP1098 surgical system (Intuitive Surgical, Sunnyvale, CA, USA) was used to perform intracorporeal ileal conduit urinary diversion by a transperineal approach after radical cystoprostatectomy and bilateral pelvic lymph node dissection. The surgery was completed through a 2.5-cm perineal incision through which a GelPOINT Mini advanced access platform (Applied Medical, Rancho Santa Margarita, CA, USA) and a dedicated 25-mm multichannel port accommodating a 12-mm × 10-mm oval articulating robotic camera, three 6-mm double-jointed articulating robotic instruments, and a 6-mm accessory laparoscopic instrument were placed. Moreover, at the planned level of the cutaneostomy, a 12-mm port to accommodate the Endo-GIA was placed. The primary outcomes were the technical feasibility, the operative time, and the record of eventual procedural complications. The intervention was successfully completed without any conversion or need for additional ports. The total operative time was 200 minutes. Operative time for urinary diversion was 90 minutes.

Conclusion: We demonstrated the feasibility of single-port transperineal intracorporeal ileal conduit urinary diversion using the SP1098 purpose-built robotic platform. Limitations include the preclinical setting. The applicability in the clinical model is awaited to be tested after the platform will be commercially available.
