For both mine the put the catheter in first.. with my 2nd it was elective and I was in the day surgery area.. I went out the back they got me to shower and dress in a lovely gown.. then they came by and took all my obs. (pulse, BP ect) then they gave me this foul foul drink to keep tummy acid down (or something like that) then they inserted the catheter and then I got a IV started and then just waited.. all of 15 mins then they said it was my turn

I found the catheter didn't hurt at all the first time nor did it coming out but the 2nd time it hurt a little but I may have been anxious too. and it felt uncomfy coming out as well but once that was all said and done I was almost as good as new

I hope that helps some

Good luck
