Despite widespread use of Bricker and Wallace techniques, comparative outcomes remain debated. This study compares stricture rates between these techniques under standardized surgical conditions, controlling for body habitus and without cancer recurrence-related stenosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective analysis included 46 patients undergoing laparoscopic ileal conduit diversion by a single surgeon (2017\u20132021). Patients were stratified into Bricker (n=18) and Wallace (n=28) groups, matched for BMI and comorbidities. Hydronephrosis severity was graded using the Onen system. Statistical analyses utilized Fisher\u2019s exact test, Mann-Whitney U test, and t-test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>No significant difference in hydronephrosis incidence was observed (Bricker: 11.1% vs. Wallace: 0%, p=0.148). However, the Bricker group exhibited longer operative time (301.89 \u00b1 11.76 vs. 281.32 \u00b1 10.15 minutes, p&amp;lt;0.001) and hospitalization duration (18.18 \u00b1 8.22 vs. 11.38 \u00b1 5.11 days, p=0.005). All strictures were asymptomatic (Onen Grade 1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Both techniques demonstrate comparable safety regarding stricture rates.
