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

If you talk to 3 different people with an ostomy, they may all actually be living with something very different from the others. As we discussed in our first Ostomy 101 lesson, an ostomy is essentially a non-natural opening in your body by which a person releases waste, but there is more than one type. The type of ostomy is dependent on what part of the digestive tract is used to make the stoma.

Ileostomy: This type of ostomy is made with a part of the small intestine (or ileum). It may be what-is-an-ileostomy-imageused when the entire colon has been removed (like mine) or it may be temporary following a resection or to allow the colon to heal before being reconnected. It is commonly used in patients with ulcerative colitis, Crohn’s disease, Familial Polyposis (FAP) and colon cancer. It is most often located at the lower right side of the stomach.

The poop is usually in liquid form and can be water or more of the consistency of applesauce. The individual does not have any control on the activity of the ostomy and must wear an ostomy bag, which needs to be emptied approximately 5-8 times a day.

what-is-a-colostomy-imageColostomy: This ostomy is formed with a part of the large intestine. It is used when only part of the colon is removed or when a section of the colon needs time to rest and heal and can also be either permanent or temporary. It is often used for patients who have diverticulitis, colon cancer, bowel obstruction, paralysis, injury or birth defects. There are 2 common types of colostomy that affects its placement: A transverse colostomy is on the upper part of the stomach and a descending/sigmoid colostomy on the lower left of the stomach.

The poop in a transverse colostomy is similar to the ileostomy, but may be somewhat more formed. The individual does not have control over the activity and must also wear an ostomy bag. For some who have a colostomy formed out of the descending colon, the poop may be closer to what is considered “normal”. In some cases, the individual may have an option of “irrigating” their ostomy (essentially an enema through the stoma) which may give a degree of control over the ostomy activity and some may even have the option to wear a plug over the stoma, rather than a bag.

what-is-an-urostomy-imageUrostomy: This type of ostomy is used for the urinary tract. It is actually a little more complicated than the other types of ostomies as it requires the removal of the bladder, as well as a section of the small intestine. The intestine is sewn back together, but the piece that was removed is then attached to the ureters that extend from the kidneys and is also used the create a stoma. It is only done as a permanent solution. A urostomy is most often needed due to bladder cancer, but also inflammation of the bladder or birth defects. It is usually placed on the right side of the stomach.

The pee empties into an attached urostomy bag. The individual has no control over its release. It needs to be emptied approximately every 2-4 hours.

what-is-a-j-pouch-imageJ-pouch: While not a type of ostomy, I feel the need to write a quick summary of a j-pouch. It is made after the removal of the colon when the small intestine can be reattached to the rectum and anus, forming an ileoanal reservoir. This surgery is usually done in 2 stages and involves the creation of a temporary ileostomy. It is often used in patients with ulcerative colitis (but not Crohn’s disease) and FAP.

In this scenario, the individual can still go to the bathroom in the normal fashion, however, the poop is less formed than what is considered normal.

So now you know: When someone is talking about ostomies, they will most often use “colostomy” as a blanket term, but that is likely to be an inaccurate description. Don’t be afraid to ask somebody you know about theirs. We appreciate not being lumped into a particular group, especially when each type affects individuals differently.

This is a very brief overview of the types of ostomies and there is a TON more that goes into each of these, but it’s a lot more detail than for my purposes here. UOAA has some guides with lots of good information. Images were stolen from here, here, here and here, respectively.

    Is it normal to still experience some pain inside my body after having 8 hour ileostomy surgery 6 months ago ?

    I also experience some pain 2 days a week when removing my bag to change it my skin in the area where bag is still a little tender ?

    Thank for any advice

    I have an existing urostomy that was done in 2005. I now need to have a colostomy. Will I have to manage 2 bags ?

    1. jtabler

      I have thw same question only in reverse. I have a permanent colostomy and am concerned I may need an apr, and have read sometimes this requires removal of the bladder. Do people have 2 bags or is it combined? How does one live this way?

    I am now more knowledgeable about which ostomy I have. My doctor’s used the word colostamy but I saw on a report that it was an iliostomy. However, I thought they took most of my large intestines. Also, it depends on what I eat as to the make up of my discharge. I was told I could eat anything as long as I chewed my food thoroughly. So far everything is great!

    I am having a difficult time keeping my pouch from breaking loose at the top. Does not drain and mustaches up at the stomach. Does anyone have Sandy suggestions what I can do to eliminate this problem

    My mom is 66 and had a colostomy 2 months ago. She doesn’t have appetite and hardly gets out of bed. she say’s she’s fine but hardly communicates with any one. We don’t know what to do to help. Please any advice?

      Hi Gloria, I’m sorry to hear that your mother is having some difficulty adjusting. It’s so hard early on, but I think it’s so great that you are looking for ways to help! Do you know if there are any support groups in the area? Around me, there is a group you can reach out to and they will send someone from the group to talk to people who have just had surgery. That’s what made the biggest difference for me was just getting to meet someone else who had been through it and could provide some advice and understanding. I would definitely start there. If there’s not, is she someone that might consider joining an online group? Honestly, I feel like getting to know others and joining a community is one of the biggest steps to coming to terms with all of this. Let me know if there’s more I can do. You can also email me at to chat more.

    Thank you for being so candid. I have a (new) friend with a “joey”, her term not mine. This article has helped me understand the situation better, without her having to go into embarrassing details. She will talk about it but I cannot make intelligent comments because of my ignorance. So once again, thankyou

      Ruby, I am so glad you found it helpful. I think it’s so wonderful that you’re looking into more on ostomies for your friend. We need more people like you in the world!

        I have a question and the groups on FB are not private when one posts question. Goes all over FB!
        Had colostomy almost 2 yrs ago and have been told a reversal might not work due to only small Amt. colon left and too dangerous. I have a fistula in abdomen that drains. (Attached to rectum)
        Also a wound that wouldn’t heal ( size of grapefruit) so had skin graft.
        I plan to visit surgeons about repair but it’s scary though since it might be very long surgery.
        Any experience with this?

    I have a urostomy since the age of 4 (1972) due to being born with Spina Bifida. In 2017, I had to get a colostomy because of a gastrointestinal fistula and other complications. Would it ever be likely that I would ever need an ileostomy as well. I am still learning the difference between the three. Also, ever since I have had my urostomy, even as a young child, I have had major issues keeping a bag in place. My stoma is a deep iny. The ostomy team at the hospital last year were even stumped because everything has been tried. I am an overweight wheelchair user as well. Any suggestions?

    “or the descending colostomy, the poop is much closer to what is considered normal. The individual sometimes has control over the ostomy activity and may not need to wear an ostomy bag.”

    You are serious???

    When do I have control over my descending colostomy pooping and not need to wear the bag? Please tell me. And what do you mean by “poop is much closer to what is considered normal”? Can not say I have noticed that.


Sit down, stay a while. I'd love to hear from you.
