@da69, I'm so glad that you chose to see a specialist and that you wrote for thoughts and experiences of others here. Searching on the internet can be informative, but also scary. I know you're making a list of questions. Here are some of the questions I would want to ask:

What is the predicted outcome of surgery?
What are the risks?
How will post-operative pain be managed?
Will I urinate normally after treatment?
How long will I need the temporary catheter?
What can I do pre and post-operation to improve my recovery?

I'm also tagging a few additional members like @jakedduck1 @jimb1950 @predictable @upstatephil to see if they have experiences to add, especially regarding recovery and pain levels, to help you prepare for your upcoming consult.
