The ileopsoas tunnel, a new antireflux technique for ureteroileal reimplantation: an experimental study in dogs.
A new antirefluxing ureteroileal anastomosis is described in which the implanted ureter is placed between the ileal segment and psoas muscle. The procedure was studied in eight experimental dogs, which were observed for 20 weeks. Radiologic and bacteriologic examinations, necropsy assessment and histopathologic results provided evidence that this ileo-psoas tunnel technique allows a unidirectional, non-obstructed flow of urine. The technique could be applied when ileal replacement of the ureter is necessary or in association with continent bladder replacement.
