I am sorry; having to face an operation with on older piggy is always a major leap of faith!
The good news is that generally bladder stone operations on sows are pretty straight forward and they tend to heal well and without any complications. it is going to take 2-3 days for the body to settle after the operation, so you have to factor that in. I found that a spay was a worse operation to recover from than a bladder stone one. How well also depends on how complicated/long the operation is and how much damage there is to the bladder.
What you can do for post op care:
- please ask your vet how soon after the operation Rosie can have painkillers and if necessary a gut stimulant.
- keep her on light vetbed, flece or towels. A little bleeding during the first 2 days is normal, but any large amount needs to be seen asap. Change any soft bedding and/or cosies daily or preferably twice daily at first.
- If it makes her happier, she can have a companion with her as soon as she is eating normally and is chipper.
- Make sure that you have got everything for hand feeding, as well as probiotics etc. in case she's not got her appetite back. Do not hesitate to step in order to keep the guts working. Also offer as much water as she will take, as flushing any bacteria out of the system will also help.

- Check at least once or twice during the first night that Rosie is leaving her operation scar alone and is not pulling out any stitches or gnawing on it.
- See your vet or an out-of-hours vet promptly in case Rosie doesn't pick up or is becoming very apathetic at any stage; the same goes if she seems to be in real pain.
- if Rosie is not yet on bladder wall coating vegetarian glucosamine or glucosamine based cystease/cystaid etc., you may want to look into that to help ease the discomfort and protect the walls.
- you may want to look into low calcium diets, pellets and filtered water to minimise the chances of a reoccurrance/new build up if that is possible. It depends on what is causing the stones. Not all factors can be controlled, as there is sadly still very little research.

The IS diet has been integrated into our general diet recommendations; it is listed under "daily veg" (just leave away any other veg, herbs and fruit). We would recommend feeding 5 low calcium Bunny pellets per piggy per day with it; they are the currently best available brand.

Wishing your girl all the best! My Ceri had an emergency bladder operation at a similar age and at very low weight (540g) after a rapid sudden weight loss, but she made it through thanks to a very good vet and was back to over 700g within two weeks of the op, so it can be done!
