Bladder bowel fistula, freaking out

Hi, I've been a reader on here for a while now but this is my first time posting. I'm 21 and have had crohns for almost 10 years now with relatively no issues(only a handful of flare ups in those 10 years, no daily symptoms or diet restrictions). Well controlled with Pentasa.
I have an appt with a specialist on Friday, but I'm 99.9% sure I have a bowel bladder fistula. I've had uti's on and off for about 6 months, and have been noticing gas and little bits of.. er, matter, coming from my bladder as well.
Well I did some Internet researching on my own about it(bad, I know!) and now I am completely freaked out, reading things about bowel resections, catheters, giant incisions, and my worst fear, colostomy bags. Has anyone been through this? I'm just looking for some experiences and support. Thnx!

@spookydeuce..I have a rectovaginal fistula which have had for a few years, I would feel gas, have stool etc come out of my vagina so my gi doc glued it closed...I go for a scope and stricture dilation every three months at which time he will glue if needed. I now have a fistula on the outside near my groin that he just cut open but it closed in the last two weeks so I am freaking out.

oh spookydeuce - it's beyond horrid isn't it.  I have been experiencing the same and finally (its taken some time) a bowel to bladder fistula was confirmed via MRI just prior to Christmas.  I knew it was all along, like you with the constant UTI's. then wind, then bowel matter.  All my tests have been done now and I am also seeing my consultant this week, a day before you, on Thursday.  I'll post back what news I have, I know I will be going back on infliximab/remicade as that successfully healed a fistula that came out on the skin.  I too wonder about surgery but with the pain I have I would seriously consider it, I'm even going to ask to discuss it.  I had a right hemicolectomy in 1999 which meant I had to have a colostomy for a year.  After the initial pain of the operation I felt better almost immediately and honestly my experience of having an ostomy was a favourable one.  Hopefully it won't come to that for either of us, thankfully it seems from other posters that this type of fistula can be treated without a huge operation.  Please let us know how you get on, I am thinking of you.
