Comparative outcomes of internal, external, and no stent in ureteroileal anastomosis for ileal orthotopic neobladder reconstruction.

Background: Ureteral stents, including internal stents and stentless techniques, are commonly employed in urological procedures such as urinary stone management and deformity correction. However, their use in radical cystectomy for bladder cancer remains relatively limited. This study aimed to compare the efficacy of internal stent, external stent, and no-stent treatments for ureteroileal anastomosis in laparoscopic radical cystectomy (LRC) combined with ileal orthotopic neobladder (IONB).
