    Abstract:
    INTRODUCTION: We aimed to investigate the differences in perioperative outcomes, especially ureteroenteric strictures, between patients who underwent a stented ureteroenteric anastomosis at the time of robot-assisted radical cystectomy (RARC) and ileal conduit vs those who did not. METHODS: A retrospective review of our RARC database was performed (2009-2023). Patients were divided into those who received stented ureteroenteric anastomosis vs those who did not. Propensity score matching was performed in the ratio of 3 (stented ureteroenteric anastomosis) to 1 (stent-free) in terms of age, gender, BMI, race, American Society of Anesthesiologists score, neoadjuvant chemotherapy, Charlson Comorbidity Index, prior radiation therapy, previous abdominal surgery history, clinical T3/clinical T4 stage, preoperative metastasis, and preoperative hydronephrosis. A cumulative incidence curve was used to depict ureteroenteric strictures and a Cox regression model was used to identify variables associated with ureteroenteric strictures. RESULTS: Four hundred eighty-eight patients underwent RARC, 366 individuals underwent a stented ureteroenteric anastomosis, and 122 patients underwent a stent-free approach. There was no significant difference in 90-day overall complications, high-grade complications, readmissions, UTIs, leakage, and ileus (P > .05). Ureteroenteric strictures occurred at a rate of 13% and 18% at 1 and 2 years, respectively in the stented group, vs 7% and 10% in the stent-free group (P = .05). Stent placement was significantly associated with ureteroenteric strictures. CONCLUSIONS: Stent-free ureteroenteric anastomosis was associated with fewer strictures following RARC and ileal conduit.
