An experimental study in dogs showed that the implantation of hydroureters onto a denuded area of the bladder muscle led to mucosal regeneration and formation of a submucosal tunnel. Reflux was prevented in all animals when the bladder wall was immobilized at the reimplantation site by fixation to the psoas muscle. Urinary stasis normalized after 10 to 12 reimplantations. Internal ureteropexy would seem to be a most simple and satisfactory technique for preventing reflux when dissection of a submucosal tunnel fails in ureteroneocystostomy. It has been used in three patients with good results.
