Rectal Spacers Use in Prostate Cancer Radiation Therapy

Peri-rectal hydrogel spacer consists of a layer of polyethylene-glycol gel (SpaceOAR vue) in order to outdistance the prostate from anterior rectal wall

The balloon spacer is a biodegradable balloon made of poly (L-Lactide-co-caprolactone) which is a co-polymer of Poly Lactide acid and epsilon Caprolactone (BioProtect Balloon Implant System, BioProtect Ltd) inflated with saline, providing around 18 mm space height , and can be deflated and repositioned if needed, both laterally and along the distal /proximal planes, for optimal uniformity of spacing.
