Background: Radical cystectomy (RC) has been considered the standard management of muscle-invasive bladder cancer. Despite the improvements in surgical techniques and perioperative care, RC is still associated with high perioperative morbidity and mortality. Objective: This study aims to evaluate the effect of retroperitonealization of ureteroileal anastomosis on perioperative complications of RC with ileal conduit urinary diversion. Patients and methods: This is a retrospective cohort study. We reviewed medical charts of 876 patients who underwent RC between 2016 and 2021. Based on the inclusion and exclusion criteria, 748 patients entered the study. According to retroperitonealization of the ureteroileal anastomosis, patients were categorized into two groups (group I without retroperitonealization of the ureteroileal anastomosis and group II with retroperitonealization of the ureteroileal anastomosis). Patients’ characteristics and occurrences of any complications and high-grade complications were compared between these groups. Results: In comparing the complication categories between the two groups, fewer patients in group II suffered from gastrointestinal, urinary, and cardiac events (p values were 0.018, 0.021, and 0.013, respectively). Moreover, fewer patients in group II experienced any complications and high-grade complications (p values were < 0.001 and < 0.001, respectively). The length of hospital stay was also significantly shorter in group II (p < 0.001). Conclusions: RC is associated with comparatively high perioperative morbidity and mortality. In the present study, 61% of the patients experienced at least one complication postoperatively. Retroperitonealization of the ureterointestinal anastomosis may decrease perioperative adverse events of RC with ileal conduit urinary diversion.
