Comparison of Different Ileal Neobladder Construction Schemes After Laparoscopic Radical Cystectomy in Patients with Invasive Bladder Cancer
Objective To compare the effects of different ileal neobladder construction schemes after laparoscopic radi-cal cystectomy(RC)in patients with invasive bladder cancer.Methods The patients with myometrial invasive bladder cancer were prospectively included as the research objects,and were divided into 3 groups according to the random number table.All pa-tients underwent laparoscopic RC.In group A,orthotopic U-shaped ileal neobladder surgery was performed,in group B,orthotopic W-shaped ileal neobladder surgery was performed,and in group C,orthotopic ρ-shaped ileal neobladder surgery was performed.Univariate ANOVA was used to compare the operation conditions and urodynamic parameters 3 months after operation in the 3 groups,χ2 test was used to compare the recent postoperative complications in the 3 groups,Kruskal-Wallis H test and χ2 test were used to compare the recovery of urinary control function in the 3 groups.Results The operation time of group B was longer than that of group A and C,and the amount of bleeding during operation was more than that of group A and C,with a statistical signifi-cant difference(P＜0.05).There was no statistical significant difference in the exhaust time and hospitalization time among the3 groups(P＞0.05).There was no statistical significant difference in the total incidence of postoperative complications among the3 groups(P＞0.05).Three months after operation,the maximum volume of new bladder in group B was the highest,followed by group A,and group C was the lowest,with statistically significant difference(P＜0.05).There was no statistical significant differ-ence in maximum urinary flow rate,initial urinary bladder volume,new bladder compliance and residual urine volume among the 3 groups(P＞0.05).The recovery time of urinary control function in group B was the shortest,followed by group C,and group A was the longest,with statistically significant difference(P＜0.05).Conclusion Among the3 different new bladder construction schemes after laparoscopic RC surgery,the operation time of U-shaped and ρ-shaped new bladder is shorter,the operation time of W-shaped new bladder is the longest,and the amount of intraoperative bleeding is the largest,but the volume of new bladder after W-shaped surgery is the largest,the recovery time of urinary control function is the shortest,and the postoperative complications of the 3 construction schemes are less.
