<p>A biostructure is described, comprising: a substantially tubular shaped carrying mean made out of an inert, flexible and non toxic material, not effective as substrate for cells and tissues to adhere and grow; and an in vitro cultured epithelium, having at least the same length of said carrying mean, or a larger lenght, being wound as a spiral on said carrying mean, so that the basal layer of said epithelium is turned to the exterior and the apical layer of said epithelium is turned to said carrying mean. The biostructure may be advantageously used in the surgery of urethral deformities.</p> |
