机器人辅助腹腔镜单一体位肾输尿管全长加膀胱袖状切除术治疗上尿路尿路上皮癌的临床疗效分析OA

Objective To evaluate the safety,feasibility,and clinical efficacy of single-position robot-assisted laparoscopic radical nephroureterectomy with bladder cuff excision(RNU-BCE)in the treatment of upper tract urothelial carcinoma(UTUC).Methods The clinical data of 8 UTUC patients who underwent single-position RARNU-BCE using the Da Vinci Xi robotic sys-tem in Binzhou Medical University Hospital from January 2023 to June 2025(robot-assisted group)were retrospectively ana-lyzed.All surgeries were performed by the same surgeon with the patient in a modified lateral decubitus position.A specific tro-car configuration(e.g.,"lightning"layout)was used,and the entire procedure,including kidney mobilization,complete ure-terectomy,lymph node dissection,and bladder cuff excision,was completed in a single position without the need for patient repo-sitioning or robot redocking.Operative time,intraoperative blood loss,postoperative complications,hospital stay,pathological results,and short-term follow-up outcomes were recorded and analyzed.Results All 8 procedures were successfully completed without conversion to open surgery.The mean operative time was(233.25±66.5)minutes,and the mean intraoperative blood loss was(175±46.3)mL.No major postoperative complications(Clavien-Dindo grade≥III)occurred.Postoperative pathology confirmed UTUC in all cases with negative surgical margins.During a follow-up period of 2-6 months,no signs of tumor recur-rence or metastasis were observed in any patient.Conclusion Single-position robot-assisted laparoscopic RNU-BCE for UTUC offers advantages such as a clear surgical field,precise manipulation,minimal intraoperative bleeding,and rapid postoperative recovery.It is a safe,feasible,and effective minimally invasive surgical technique.The integrated procedure eliminates the need for intraoperative repositioning,simplifies surgical steps,and may potentially reduce surgical trauma and total operative time.Short-term tumor control outcomes are satisfactory.
