A sterile, bioabsorbable material intended for submucosal injection in the urinary tract (urethra, urinary bladder, and/or distal ureter) to add volume by serving as a space-occupying supplement (bulking agent) to the intercellular matrix of connective tissue in the treatment of stress urinary incontinence (SUI) and/or vesicoureteral reflux (VUR); it does not include a local anaesthetic agent. It is in the form of a gel of biosynthesized dextranomer microspheres and hyaluronic acid (HA) derived from bacteria. The material is typically preloaded in a disposable syringe.
