If you are going to have radiotherapy as part of your prostate cancer treatment, you may be researching the possible side effects of the procedure. Most patients will experience an increase in the need to urinate, a weak urinary stream, difficulty even starting urination and diarrhoea in the weeks after radiotherapy.
Thankfully, there is a follow-up procedure known as SpaceOAR® Hydrogel, which can be used to minimise the harmful and unpleasant side effects of prostate radiotherapy. Consultant urologist Mr Neil Haldar explains how it works, the benefits and its effectiveness.
What is the SpaceOAR® Hydrogel?
The SpaceOAR® Hydrogel was designed to reduce radiation exposure to the organs surrounding the prostate during prostate radiotherapy. The reduction in radiation exposure to surrounding organs can reduce the side effects such as rectal bleeding, loose bowel motions, urinary incontinence and impotence. (See references at the end of this article).
What happens during the procedure?
SpaceOAR® Hydrogel is a soft gel implanted between the prostate and rectum to create a space. This space is important as it pushes the rectum away from the prostate and therefore, the radiotherapy field.
This allows a maximum dose of radiotherapy to be delivered to the prostate gland and therefore to the prostate cancer whilst avoiding unnecessary irradiation of surrounding tissue. This, therefore, minimises harmful and potentially unpleasant side effects.
The gel is implanted through a minimally invasive procedure under ultrasound guidance. The SpaceOAR procedure is usually performed under local anaesthetic. The gel remains in place for up to six months, whilst it is naturally absorbed by the patient’s body.

How safe is SpaceOAR® hydrogel?
SpaceOAR® hydrogel has been implanted in over 50,000 men worldwide and evaluated in over 60 publications. The studies have consistently found that SpaceOAR is safe and effective.
What are the benefits?
The studies in patients undergoing prostate cancer radiotherapy report benefits, including:
