Abstract:
Objective To investigate the feasibility and efficacy of robot-assisted Wallace ileal conduit in the treatment of ureteral obstruction following radical cystectomy.Methods A retrospective analysis was conducted on the clinical data of 8 patients with postoperative distal ureteral obstruction after radical cystectomy treated at the First Affiliated Hospital of Nanjing Medical University during Aug.2018 and Jun.2024.The cohort included 7 males and 1 female,aged 51-68 years(mean:58.8 years).Preoperative imaging confirmed the obstruction site and predicted its etiology.All patients underwent robot-assisted Wallace ileal conduit and were regularly followed postoperatively.Perioperative data were statistically analyzed.Results All 8 procedures were successfully completed.The operation time ranged from 120 to 398 minutes(mean:298.38 minutes),and intraoperative blood loss from 50 to 300 mL(mean:112.5 mL).Postoperative complications occurred in 3 cases according to the Clavien-Dindo classification:one Grade Ⅰ and two Grade Ⅱ,with no major postoperative complications(Grade Ⅲ and above)observed.During a follow-up of 21-77 months,hydronephrosis and renal function showed varying degrees of improvement.Conclusion Robot-assisted Wallace ileal conduit is safe,feasible,and effective in the treatment of ureteral obstruction following radical cystectomy.However,for malignant obstruction caused by tumor recurrence,combined comprehensive therapy is necessary to reduce recurrence risk.
