Serous-lined extramural tunnel technique for uretero-ileal implantation in urinary diversion.

Objective: We present our initial experience of a serous-lined extramural tunnel technique for anti-refluxing uretero-ileal anastomosis in five cases of orthotopic ileal bladder and four cases of continent ileal pouch.

Results: Ureters were implanted into serous-lined tunnels formed from a detubularized W-configurated ileal segment. Neither upper tract dilatation nor reflux were observed in any patient postoperatively.

Conclusions: The technique can provide an effective uretero-ileal anastomosis for reflux prevention with minimal use of the ileal segment and without the use of any artificial materials.
