摘要

Purpose

Ureteroileal anastomosis is a critical step in robotic radical cystectomy with intracorporeal ileal conduit for bladder cancer. This study compares perioperative outcomes and complications of Wallace versus Bricker techniques, addressing the limited data available in the robotic-assisted setting.

Methods

We retrospectively reviewed 96 bladder cancer patients who underwent robotic cystectomy with intracorporeal diversion (August 2018–July 2024), comparing outcomes between Bricker and Wallace ureteroileal anastomosis techniques. Demographics, perioperative data, and complications were analyzed.

Results

Among 96 bladder cancer patients, 72 underwent Bricker and 24 underwent Wallace anastomosis. Demographics were similar between groups (age: p = 0.097; gender: p = 0.204). Operative time was shorter in the Wallace group (246 vs. 260.5 min, p = 0.160), though not statistically significant. Postoperative outcomes were comparable, including rates of hydronephrosis requiring intervention (12.5% vs. 15.8%, p = 0.694). Chronic ureteral strictures occurred only in the Bricker group, although this difference did not reach statistical significance (13.8%, p = 0.055), and urine leaks were observed in two Bricker patients, with none in the Wallace group (p = 0.594). Median length of stay was 7 days for Wallace and 5 for Bricker. There were no significant differences in 30-day or 90-day readmission rates between the two groups.

Conclusion

In this single-institution study, Bricker and Wallace anastomoses during robotic cystectomy showed no significant differences in strictures, complications, or readmissions. Wallace showed favorable trends, but these were not statistically significant. Both techniques appear safe; larger studies are needed to assess potential advantages of Wallace.
