Can Radiation of Prostate cause Urine Retention?

I had urine retention from week 3 of a four week RT treatment in early 2019. I was prescribed Tamsulosin which fixed it almost immediately. I stayed on Tamsulosin for about two months after RT finished and then, after taking advice from my GP, gradually reduced the dose over the next two months.

It's worth asking your Oncologist about SpaceOar which is hydrogel inserted in the space between the prostate and the bladder. It wasn't available on the NHS when I had my RT but I believe it's a lot more common now.

Thank you very very much Seamus. You can't imagine what it means to me having already been through the discomfort of urine retention.
