Has anyone had a formed scar tissues post PVP procedure that blocked the flow?

Here is my situation: On the 12th of January this year (2006), I had my PVP
procedure. The result was as follows:
1. Retro ejaculation
2. Burning sensation for over 6 months
3. After an initial strong flow, it started to get weaker and weaker that it
became worst than before the procedure.

Early August, I saw a different uro who performed a systoscopy and advised
that I had scar tissues that formed and blocked the flow. He attributed them
to a weak blood flow in the prostate as a result of the PVP laser. Last Tue,
9/5/2006, he performed what he called a Mini-Turp to remove these tissues
surgically. I stayed one night in the hospital for observation and the
catheter was removed yesterday (Friday 9/8). I'm recovering now, the burning
sensation is tolerable, and the flow is ok. However, in my talking to him
post the procedure, he indicated that there is a 10-15% chance that new scar
tissues may form again in the future.  
My question is: Has anyone experienced this condition? Is there anyone who is
knowledgable of this condition? I'm very concern that I may have this problem
again and again in the future.
Would appreciate any information.
