Haven?t been here in a couple years and a search didn?t show this having been discussed, so my apologies if this has been asked and answered repeatedly...

I?ve been using 16fr Duettes in my SP for 6 months and they?re miracles. But last month it was a bear to get in. This morning it wouldn?t go in AT ALL. I fought with it for 15 minutes and it?s like the tip is bigger than 16, and it just won?t fit. I had some regular latex caths in the house thankfully, and that slid right in. It?s driving my bladder nuts already, though, and I want it out ASAP.

Are there variances with some some of the Duettes? Why is it suddenly so hard to put in? Is there a trick to it?
