Initial experience of the Versius robotic system in robot-assisted radical prostatectomy: a study of 58 cases.

Introduction: The study presents the initial outcomes of robot-assisted radical prostatectomies (RARPs) using the Versius robotic system in a urological centre with no prior robotic surgery experience.

Material and methods: A retrospective analysis of 58 RARPs was conducted, including patients' parameters as well as Versius system performance.

Results: The study involved 58 patients (average age 66.9 years). Median preoperative prostate specific antigen (PSA) was 9.8 ng/ml, with 48% having ISUP grade group ≥ 3 on biopsy and 25.8% showing extraprostatic extension on MRI. Median blood loss was 437 ml, with complications (10.3% Clavien-Dindo grade II and 4 grade III cases). One conversion to open surgery occurred (0.58%). Final pathology revealed 46.5% extraprostatic disease, and 25.8% had positive margins. Post-surgery, 96.5% had undetectable PSA at 6 weeks. Continence rates were 89.7% at 6 weeks, increasing to 91.3% at 12 months. Median catheter duration was 7.9 days, and the hospital stay was 4.5 days. Console time averaged 150.9 minutes, with a median operative time of 213 minutes. The Versius system reported medium priority alarms in 24.1% of operations, including 1266 alarms related to robotic arm clashes and 43 instrument swaps. One bedside unit exchange occurred with no console or robotic system failures.

Conclusions: The Versius robotic system can be successfully introduced in a urological centre without prior robotic surgery experience. Our setup and operating room positioning are effective, safe, and reproducible. We encountered and resolved surgical and technical challenges. Further follow-up studies are needed to assess the system's performance.
