Transition from da Vinci to Versius robotic surgical system: initial experience and outcomes of over 100 consecutive procedures

We sought to describe the development of the robotic urology program at Sindh Institute of Urology and Transplantation (SIUT) and the feasibility of transitioning from the da Vinci to Versius robotic systems. The SIUT robotics program began in 2017 utilizing the da Vinci Si robotic system, transitioning to the Versius system in 2021. Retrospective review of our quality assurance database was performed. All procedures performed utilizing the two systems were identified, analyzed, and compared. Data were described with descriptive statistics. Matched procedures (by type of procedure) performed by the same surgeons utilizing the da Vinci and Versius were compared. All tests were double-sided with statistical significance set at p < 0.05.106 cases were performed by the Versius robotic surgical system in 2021. Median age was 42 years (IQR 26–56), and 69 (65%) were males. Procedures included both benign (83%) and malignant disorders (17%), several upper tract (75%), and pelvic/lower tract (25%). No major intraoperative complications were observed. Conversion to open occurred in six procedures. Malfunction of the robotic arms occurred in two procedures: the erroneous bedside units (BSU) were replaced. Eight patients developed postoperative high-grade complications. Matched analysis of various procedures (pyeloplasty, stone surgery, radical, partial, and simple nephrectomy) showed no significant difference in perioperative outcomes. To our knowledge, this is the first and largest series of urologic procedures performed by the Versius robotic surgical system.
