Dear cheries:
Per my squire, I'll weigh in on your question.
Actually, the reaction quoted on the other web site is quite unusual. Not only have I had the brachytherapy but I did a TON of research prior to the procedure so I can say that with some certainty.
However, as others have said, there may be issues...general or isolated...with any procedure. Prior to brachytherapy, most experienced doctors will ask the patient to take a quick survey (I can't recall the name of it) to determine their urinary issues that exist prior to the procedure. It may be that the patient mentioned in the other post had significant urinary issues prior to seeding. If so, those issues are likely to be worse after the procedure. On the flip side, if the urinary stuff works ok pre-procedure, there is a high liklihood of few post procedure problems.
There are short term urinary side effects that are usual with brachytherapy. These include potential frequency and urgency as well as the rare but possible inability to go and the need for catherization. Those are usually handled with a Flomax prescription that works for almost all men. In my case, I took Flomax for 3 months. I did experience a little bit of frequency, no urgency and no other problems. Everything else was totally normal including no ED issues. If you would care to read a fairly lengthy description of my "Brachytherapy Journey", just click the link at the bottom of my signature.
If you want to provide some more info re your case, e.g. Gleason, number of cores postive, % positive, prostate size, your age, PSA scores, etc. there are many folks here that can provide (non-medical, but informed) advice about your situation.
Good luck and let us know how we can help.
