[Initial study of an experimental model for bladder augmentation].
Since Coffey described in 1910 the Uretero-sigmoidostomy, the first auto-continent urinary derivation, many techniques have been developed and used for bladder augmentation, although none of them has been considered fully satisfactory. The availability of a product made of a bovine collagen and glycosaminoglycan base, used for regenerating dermis and oral mucosa induced us to start this study on rabbit bladder in order to verify if muscular fibers might grow in its interior. For that purpose we used 6 New Zealand rabbits, to which we implanted a fragment of artificial dermis inside the detrusor after dissecting it. We present our results after 3 and 6 weeks postoperatively.
