Summary
Robotic laparoendoscopic single-site surgery (R-LESS) using new VeSPA instruments proved feasible and efficient in pig kidney procedures. This novel technology offers enhanced instrument stability and ergonomics for urological applications.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Robotic Surgery
Background:
- Robotic laparoendoscopic single-site surgery (R-LESS) aims to reduce invasiveness.
- Novel instrument development is crucial for advancing R-LESS techniques.
Purpose of the Study:
- To introduce and evaluate novel R-LESS instruments (VeSPA) in a preclinical urological setting.
- To assess the feasibility and efficiency of R-LESS kidney surgery in a porcine model.
Main Methods:
- The VeSPA instruments were used with the DaVinci Si system through a single umbilical incision.
- Sixteen procedures (pyeloplasty, partial nephrectomy, nephrectomy) were performed in 4 pigs.
- Technical feasibility, efficiency, and perioperative outcomes were assessed.
Main Results:
- All 16 R-LESS kidney procedures were completed successfully without conversion.
- Mean operative time was 110 minutes with minimal blood loss (20 mL).
- No major intraoperative complications or robotic system failures occurred; instrument clashing was minimal.
Conclusions:
- R-LESS kidney surgery with VeSPA instruments is feasible and efficient in a porcine model.
- The system provides excellent range of motion, stability, and ergonomics.
- Further refinements are anticipated to optimize R-LESS for urological procedures.
