Ed,
The nurse or whomever told you it doesn't hurt doesn't have much common sense.
Your original problem was prostate constricting your urethra which caused urine to be retained in your bladder. By the way, I think that is a risk factor for bladder cancer all by itself as the longer urine stays in the bladder, the longer the carcinogens that the body is trying to expel through urine stay in contact with the bladder wall. No studies on that yet but it is a theory of mine.
In any case, if your prostatic sphincter is so tight that you have retention issues, it makes perfect sense that trying to push something through there would hurt like the dickens.
I had issues but it wasn't super painful and it only hurt when they pushed through that spot.
What did help was having them put the numbing gel in there and then waiting for 10 minutes for gel to work.
Also some people have problems with small urethra which I would also imagine could cause some pain.
I think that laser reduction procedure actually takes a while to work so it could be it hasn't reduced the constriction yet. You should talk to the urologist (not the nurse) about that.
