Ileostomy, colostomy, urostomy: What’s the difference?

I came across this site the other day and thought it could be helpful for those with IBD who may be facing an ostomy. It's a personal blog with a lot of information. The blogger's name is Stephanie Hughes and she was diagnosed with Crohn's Disease in 1999 when she was 13 years old. She is a writer, a health activist and a triathlete. This particular page talks about the differences between an ileostomy, colostomy and a urostomy, but there is more information on her blog including a list of resources for IBD (many from the US).
