Efficacy and safety of robotic-assisted laparoscopic "one-step" radical nephroureterectomy and bladder cuff excision.

Objective: To investigate the effect and safety of robotic-assisted laparoscopic "one-step" radical nephroureterectomy and bladder cuff excision.

Methods: The clinical data of 69 patients who underwent robotic-assisted laparoscopic "one-step" radical nephroureterectomy and bladder cuff excision at the Department of Urology, Zhongda Hospital, Southeast University, from January 2019 to June 2023 were retrospectively analyzed, and the surgical position, Trocar position, and key surgical steps were described, and the perioperative conditions, postoperative complications, and tumor recurrence rate at 1 year after the operation were also counted. The perioperative period, postoperative complications, and tumor recurrence rate at 1 year after surgery were also described.

Results: All 69 surgeries were successfully completed, the operation time was (149.66 ± 30.10) min, the bleeding volume was (64.57 ± 23.49) mL; the drainage tube was removed in (3.12 ± 2.41) days, the average hospitalization days were (4.62 ± 2.10), and 8 patients had Clavien-Dindo grade II complications. During the follow-up period, 3 cases of tumor recurrence, 1 case of incomplete intestinal obstruction, and serum creatinine (102.96 ± 37.03) µmol/L were detected.

Conclusions: Robot-assisted laparoscopic "one-step" radical nephroureterectomy and bladder cuff excision has a good safety profile, which can effectively minimize the occurrence of postoperative complications, improve the prognosis and increase the survival rate of patients.
