Were you awake for that?? I’m not a urologist (I’m a colorectal surgeon) no we don’t pay for pain killers ourselves, I can’t speak for your surgeon but I ask my anaesthetists to give an epidural for most of my procedures and I use an ungodly amount of local anaesthetic after suturing because I find that stitches are painful and don’t really work with pain killers.
I know from my training how they do uteric stents, and I would have prescribed codeine, paracetamol, ibuprofen and some liquid morphine(not much just enough to cover the weekend) because pain is horrible and really impacts recovery, healing and mental health.
Are you at home? If so can you call your chemo line and be honest and say that you need better pain management? They should be ok to prescribe you something asap because it’s about to be a weekend and you can’t be left in pain.
