Bill,
I suggest you tell them in no uncertain terms that you are NOT pleased with them using a #16 catheter.
It is not required to use that size.
Print this out and bring it to them or ask them to read that peice of paper that comes with the BCG when they order it.
www.mcn-policy-library.com/Policy-procedure-documents/49/BCG-Instillation.htm
It clearly states in the instructions to use a #14. Other's have said they were instilled using a #12. If it takes a little bit longer to get it to drain with #12, so what?!? Patient comfort should be a factor. If they have people who have no problem with a #16 (or a half inch pipe), then good for them. Let them use that on them, but not on you.
Tell them you would like to try the #14 next and if that still causes pain, then go down a #12. Also, per the instructions, make sure they are putting the ky jelly on the catheter as well.
Sounds like some folks from back in the Inquisition times have been reincarnated as urologists! #16?! Sheesh!!!
For those that are interested, here is a link to the French Catheter scale:
en.wikipedia.org/wiki/French_catheter_scale
. It shows the sizes.
Better Luck on the next go!
Mike
