Advantages of robot-assisted laparoscopy in the treatment of ureteroenteric anastomotic stricture:a comparative analysis with endoscopic balloon dilation
Objective:To compare the efficacy between robot-assisted laparoscopic ureteral reimplantation(RAUR)and endoscopic balloon dilation in treating benign ureteroenteric stricture(UES)after radical cystecto-my.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent RAUR(28 cases)or balloon dilation(16 cases)for UES in Zhejiang Provincial People's Hospital from January 2015 to Decem-ber 2022.Additionally,9 patients underwent RAUR after failed balloon dilation.Perioperative indicators such as operation time,blood loss,complication rates,and treatment success rates were compared among the three groups.Results:The baseline characteristics were comparable among the three groups(P＞0.05).The operation time of the RAUR group and the balloon-then-RAUR group was longer than that of the balloon group(both P＜0.001),and blood loss was slightly higher(P＜0.001,P=0.020).The treatment success rates of the RAUR group,balloon-then-RAUR group,and balloon group were 92.86％,88.89％,and 62.50％,respectively,with a statistically significant difference(P=0.031).The overall success rate of the combined two RAUR groups was 91.89％,significantly higher than that of the balloon group at 62.50％(P=0.027).The incidences of postopera-tive grade Ⅱ complications were 10.71％,11.11％,and 6.25％respectively,with no statistically significant difference(P=0.872).No grade Ⅲ or higher complications occurred.Conclusion:For UES after radical cystecto-my for bladder cancer,RAUR has a definite efficacy and controllable complications.
