Augmentation Cystoplasty Using an Autologous Neo-Bladder Construct

Subjects will undergo an open full thickness bladder biopsy from which autologous urinary bladder smooth muscle and urothelial cells will be procured and expanded ex vivo. After approximately 5 - 7 weeks, expanded cells will be seeded on a biodegradable scaffold to produce the neo-bladder construct that will be surgically implanted onto an opened native bladder during an augmentation cystoplasty.
