Abstract

Background: Ureteroileal anastomotic stricture (UIAS) remains a critical complication following ileal conduit urinary diversion for muscle-invasive bladder cancer (MIBC). 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. Methods: A retrospective analysis included 46 patients undergoing laparoscopic ileal conduit diversion by a single surgeon (2017-2021). 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's exact test, Mann-Whitney U test, and t-test. Results: 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 ± 11.76 vs. 281.32 ± 10.15 minutes, p<0.001) and hospitalization duration (18.18 ± 8.22 vs. 11.38 ± 5.11 days, p=0.005). All strictures were asymptomatic (Onen Grade 1). Conclusion: Both techniques demonstrate comparable safety regarding stricture rates. Wallace anastomosis offers superior operative efficiency, while Bricker requires additional time for technical precision. This study highlights the importance of standardized surgical protocols and long-term surveillance in optimizing urinary diversion outcomes.

  • One 2025 oncology paper on ureteroileal anastomotic techniques had 18 of 30 verified references (60%) fabricated; these were topic-specific, credited to real urologists, and dated 2023 or 2024.

    “A 2025 paper on ureteroileal anastomotic techniques in an open access oncology journal contained 18 (60%) fabricated references of 30 verified; each fabricated reference was tailored to the paper's narrow surgical topic, attributed to real urologists, and bore claimed publication years of 2023 or 2024.8”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
