Carlos, I am the resident "expert" on chronic strictures. SRT can most definitely create additional stricture problems by itself. It's not super common, but hardly rare. My prior stricture issues from surgery, including 2 emergency dialations and 3 corrective surgeries, were only made worse with the SRT I underwent. This history was the main reason, that I had a suprapubic catheter the entire time I was undergoing SRT. The thinking was that my uro did not want me to deal with an emergency stricture situation in the middle of SRT or after, since I was prone to them.
With some guys, the sticture issues are a one or two time event, and normally a dialation or two will cure the issues. With a few of us, the stricture become chronic. I have read numbers in the 2-4% range of patients. Subicsquid and Pigeonflyer are two examples of guys here that had short term problems with strictures.
The SRT can cause some serious swelling issues during and after, especially at the bladder neck to urethra connection, which is touchy to begin with after surgery.
I hope for you, this dialation cures what woes you there, but if you suspect you are losing your flow, don't wait too long to contact your uro.
You definitely don't want it to become an emergency situation, and you don't want it to be an ER situation, as many ER's aren't properly geared to handle it without further damaging you in such a critical area.
I wish you best luck, and hopefully you won't be dealing with it again.
