Single port robotic assisted reconstructive urologic surgery-with the da Vinci SP surgical system.

Single port (SP) robotic assisted laparoscopic surgery was approved by the FDA for urologic surgery and clinically available in 2018. This new robotic system enables a camera and 3 separate instruments, with fully wristed motions, to be placed through a single 25 mm port. This system was designed to perform complex surgery in narrow deep spaces making it very suitable for complex urinary tract reconstruction surgery. This paper will describe our early experience of using the SP system for several types of urinary reconstruction procedures and will present our lessons learned, surgical philosophy to using the SP and early data. As with all new technologies, there is an associated learning curve and nuances to be discovered and overcome.

The da Vinici SP™ surgical system was acquired and delivered to at our institution in January 2019. Five high volume robotic urologic surgeons at our institutions underwent certification with the da Vinci SP™ and have been adding this technology into their armamentarium. Almost all cases were recorded for quality improvement initiatives and evaluated with the goal of creating standard operating procedures in terms of access, steps of procedure and minimizing pit falls. Data from all patients undergoing SP urinary tract reconstruction that were entered into our prospective institutional database were reported.

From 1/2019 to 8/2019 we have performed 71 urologic SP cases with the SP of which 18 were for urinary tract reconstructive procedures. These cases included 15 pyeloplasties, 1 buccal mucosa ureteroplasty, 1 ureteral implant and 1 repair of vesico-vaginal fistula. This paper outlines our standard operating procedures for table positioning, port placement, access and surgical steps for these complex SP cases. Our early data suggests that use of the SP system for urinary reconstruction is safe and reproducible.

The SP robotic surgical system has the potential to be used for nearly all robotic urologic reconstructive procedures. Advantages include a superior cosmetic result and ability to access all surgical quadrants without re-docking or repositioning. Limitations include no near infrared fluorescence imaging, smaller working space and slightly increased difficulty with retraction. We believe these obstacles will be overcome with time and experience. The da Vinci SP™ surgical system, in our initial experience, appears to be as safe and effective as its multiport counterpart for reconstructive surgeries.
