Summary
This study shows the new KD-SR-01™ robot system is safe and effective for robot-assisted nephroureterectomy (RANU). It offers advantages in cost and maneuverability for this complex cancer surgery.
Area of Science:
- Urology
- Surgical Robotics
- Oncology
Background:
- Robot-assisted nephroureterectomy (RANU) is increasingly used but limited by high costs.
- A new, lower-cost robotic surgical system (KD-SR-01™) has been developed in China.
Purpose of the Study:
- To evaluate the safety and efficacy of the KD-SR-01™ Surgical System for RANU.
- To assess the system's performance in patients with upper-tract urothelial tumors.
Main Methods:
- Prospective study of 9 patients undergoing RANU with the KD-SR-01™ system.
- All surgeries performed by a single surgeon; data collected on perioperative, pathology, and follow-up outcomes.
- Key metrics included docking times, operation time, and adverse events.
Main Results:
- All 9 surgeries were completed successfully without conversion to open surgery.
- No equipment-related adverse events were reported.
- Follow-up revealed one case of bladder recurrence; docking times and operation time were recorded.
Conclusions:
- The KD-SR-01™ robot system is demonstrated as safe and effective for RANU.
- The system shows advantages in rotation boom maneuverability and cost-effectiveness.
- This represents the first verification of the KD-SR-01™ system's utility in RANU.
