A new surgical technique of robotic-assisted laparoscopic nephroureterectomy without re-docking in a single position: a single center experience.

A nephroureterectomy conventionally consists of two independent section, which will considerably prolong the operation time. We developed a novel surgical technique for robotic-assisted laparoscopic nephroureterectomy without re-docking in a single position and aimed to access the safety, feasibility, and efficiency of our novel surgical technique. From August 2021 to October 2023, 53 patients who received robotic-assisted laparoscopic nephroureterectomy were retrospectively enrolled in this study. 25 patients underwent traditional nephroureterectomy and 28 patients underwent single-position nephroureterectomy. The basic characteristics of the enroll patients, perioperative parameters, and oncological outcomes were gathered and compared between novel technique robotic surgery group and traditional surgery group. The basic characteristics between two groups had no significantly difference except for the proportion of anticoagulation therapy. The operation time in novel technique robotic surgery group was shorter than that in traditional robotic surgery group, although there was no significant difference (p = 0.403). Lymph-node dissection in novel technique robotic surgery group was obvious more common than that in traditional robotic surgery group (p = 0.037), while the incision length in novel technique robotic surgery group was obviously shorter than that in traditional robotic surgery group (p < 0.001). The oncological outcomes showed no difference between two groups. Compared with traditional robotic-assisted laparoscopic nephroureterectomy, the innovative surgical technique of robotic-assisted laparoscopic nephroureterectomy in a single position showed the advantages of less surgical time, streamlined lymph-node dissection, less trauma, and expedited postoperative recovery, which is worth promoting in clinical practice.
