Robot-assisted nephroureterectomy (RANU) has been more and more applied since 21st century. However, the high cost limits the widespread use of robot system. A relatively low-cost new robotic surgical system (KD-SR-01™) has recently been developed in China.
To assess the safety and efficacy of the KD-SR-01™ Surgical System in RANU.
Patients with upper-tract urothelial tumor and undergoing RANU with the KD-SR-01™ Robotic System were prospectively included. Surgeries were all performed by a single surgeon. Patients' demographic and clinical characteristics, perioperative data, pathology findings, and follow-up data were collected. Key Findings. 9 patients were enrolled in this study, and the surgeries went smoothly with no conversion to open. The 1st docking time, the 2nd docking time, and the operation time were 222 s, 169 s, and 202 min respectively. No equipment-related adverse events occurred. All patients were followed up for at least 3 months, and one patient experienced bladder recurrences. Conclusions and Clinical Implications. This study is the first to verify that the KD-SR-01™ robot system is effective and safe in RANU and has advantages in terms of its rotation boom during redocking and its price. This trial is registered with ChiCTR2200056672.
