Purpose: We investigated the impact of ureteral stent used in ureteroileal anastomosis in ileal urinary diversion on the post-operative non-oncological outcome of the patient.
Materials and Methods: We retrospectively evaluated all patient undergoing radical cystectomy with ileal urinary diversion in China Medical University between 2018 to 2020. The primary assessed outcome was the incidence of acute kidney injury. Other evaluated outcome including incidence of hydronephrosis, rate of discharge with percutaneous nephrostomy(PCN), gastrointestinal recovery time, length of hospital stay, creatinine level at 3 months.
Results: A total number of 71 patients who received radical cystectomy with ileal urinary diversion were included in this study. The median age of the study population was 65 years (range 43 to 79). Ureteral stent does not result in lower incidence of post-operative acute kidney injury (26.67% vs 40%, p=0.13). There was no statistical difference between two groups for the other evaluated outcome. The mean length of hospital stay for stent group vs no stent group was 18.5 and 21.7 days respectively, p=0.1. Rate of hydronephrosis, rate of discharge with PCN, gastrointestinal recovery time, creatinine level at 3 months were similar between two groups.
Conclusion: Ureteral stent for ureteroileal anastomosis in ileal urinary diversion does not produce superior results compared with patients without ureteral stent.
