Let it Flow

So there's a commercial on for a pharmaceutical that treats male urinary symptoms and voiceover guy warns that if you're going to have eye surgery, let your doctor know that you're taking this medication. From this flows This Week's Discussion Question:

If I'm having an EYE OPERATION, I need to tell the doc that I'm on some drug that's helping me PEE? What the hell is this stuff doing?

Please keep the discussion civil and do not wander off into "I thought I'd stayed awake in biology class" or "Most of my male urinary symptoms begin after a couple of beers."

Discuss.
