Theyll give you a local i would imagine. Years ago i took a cricket ball to the tackle as i was stupid enough not to wear a box, in short i went to hospital and aside from the massive swelling and bruising i couldnt pee, they tried inserting a catheter but couldnt get one in due to a small swelling.
They gave me a local and bunged only what i can describe as a thin soldering iron and burst/ cauterized the swelling so i could pee.... Nothing like the smell of your own flesh burning and peeing blood........
No lasting damage done but definitely not something to think about very often.
Hope you're ok OP, my father had his prostate cancer op.3 weeks ago so i feel your concern

After its a bit sore but thats about it, depending on the size of the tube and such /wink it can be done with nothing or numbing cream let alone a local.
