Thanks for the replies folks.
We'll have a go next season with the sponge tipped catheters and see how she goes. I'm quite certain that we weren't in the bladder - exactly the same proceedure & angles as used on the first gilt, who didn't bleed or have any problems.
Will report back in 3 weeks

Pretty certain that you didn't push it into the bladder also(would be a lot more blood). Just letting you know what the pit falls can be with the twisters.
Sponges need to be pushed relatively hardish in when using them, but not so hard that it will hurt the sow in any way.
If in correctly, should be able to pull it without it coming out(just use two fingers to gently pull on it. If pushed in far enough it should stay in position and not fall out).
The use of KY jelly is a good idea, BUT(and there is always a but...
when screwing the lid on and off dirt gets trapped inside the lid which is not a good thing.)
Everything that is pushed into your gilt/sow needs to be nice and clean. So no holding to tip of the cathetar with grubby fingers or sticking it in your mouth to hold it before using it(this has all been seen believe it or not!!)
Best is to put the cathetar in first then attach the bag after.
Little words of wisdom(been there, seen it and done it a thousand times).
Things to give you food for thought, and hope you have much fruitfulness.
