Deflux is made of frequently used biocompatible materials with an established safety profile

Deflux is a biocompatible, biodegradable, nonmigratory viscous gel that shows no signs of mutagenesis and has an established safety profile. Deflux is indicated for vesicoureteral reflux (VUR) grades II-IV in children. Deflux is injected by inserting a cystoscope through the urethra into the bladder and depositing the biocompatible gel into the mucosa of the ureteral tunnel creating ureteral tunnel and orifice coaptation.

The natural solution

Deflux consists of two biocompatible polysaccharides: Non-Animal Stabilized Hyaluronic Acid (NASHA^®) and Dextranomer (Dx).¹

Non-Animal Stabilized Hyaluronic Acid (NASHA)

• Has been used for over two decades in more than 50 million procedures worldwide²
• Undergoes a patented process to form a gel with increased viscosity and stability³
• The hyaluronic acid is synthesized by cultured non-animal sourced bacteria resulting in a pure and consistent preparation free from contaminants and viruses³
• High molecular weight increases durability within the body allowing for long-term correction of VUR³

Dextranomer (Dx) Microspheres

• Cross-linked polymer of dextran³
• Microspheres measure between 80 μm and 250 μm³
• Large size prevents any risk of migration from site of injection³

The Deflux implant is stable, remains in position, and does not disappear over time⁴

Following the injection of Deflux gel, fibroblast cells have been shown to infiltrate the implant and migrate between dextranomer microspheres. A matrix of collagen is then generated, which surrounds the microsphere. This collagen matrix effectively replaces the NASHA component of the implant.

Histology:⁵ Deflux is associated with a granulomatous reaction of the giant cell type, inflammatory
cell infiltration and implant pseudo-encapsulation. They are typical histological findings associated with implantation of a foreign material. Deflux remains safe and effective for vesicoureteral reflux in children.

Deflux should only be administered by qualified surgeons experienced in the use of a cystoscope and trained in subureteral injection procedures and must not be injected intravascularly as injection into blood vessels may cause vascular occlusion.

Please refer your appropriate patients with vesicoureteral reflux (VUR) to a pediatric urologist upon VUR diagnosis.
