Editorial Commentary: Toward Off-the-Shelf Ureteral Substitutes Using iBTA “Biotubes”

Using iBTA "Biotubes"Comparative transcriptomic analysis of human mesenchymal stem cells derived from dental pulp and adipose tissues Ureteral reconstruction for long defects remains a stubborn clinical problem.When primary repair is not feasible, surgeons borrow tissue-most often bowel-to restore continuity, accepting mucus production, metabolic issues, infection risk, and the burden of a laparotomy.An off-the-shelf, living substitute that remodels into native ureter would be a step-change.In this context, Maeta et al. [1] report a thoughtful pilot in dogs, testing an in-body tissue-architected (iBTA) collagen conduit, the "Biotube," as a segmental ureteral bridge under stenting.
