Initial Experience of Robot‐Assisted Nephroureterectomy without Intraoperative Repositioning Using a New Robotic Surgical System (KD‐SR‐01TM)

Background . 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. Objective . To assess the safety and efficacy of the KD‐SR‐01™ Surgical System in RANU. Methods . 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 1 st docking time, the 2 nd 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 .
