Godspeed, bro'! Had this same thing done a coupla years ago- it's a piece of cake! Hardest thing was having to stay still for several hours after the procedure, and not being able to get up and pee!!! Not a fan of the bedpan!
Pray that the procedure will show everything clean and green! Let me know if you have any questions- hardest thing is not knowing what to expect, and I'd be happy to provide any details on that score!
