Decreased and inadequate bladder compliance with a bladder pressure ≥40 cmH20. OR 2. New-onset of upper urinary tract changes (hydronephrosis, vesicoureteral reflux) in the last 12 months Exclusion: * Neurogenic bladder * Recent (\< 12 months) urological or intraperitoneal surgery or device implantation; recent (\<6 month neurologic surgery-brain or spine) * Any prior bladder augmentation procedure * Known or suspected limitation to obtaining omentum for implantation procedure (e.g., extensive intraperitoneal adhesions) * Any contraindication to general anesthesia * Any contraindication or known anaphylactic or severe systemic reaction to either human blood products or materials of bovine origin * Human immunodeficiency virus (HIV), hepatitis B (HBV), hepatitis C (HCV), active hepatitis A (HAV) or other known active infection * Subjects with active tuberculosis (TB) requiring treatment in the past 3 years.
