What Is An Ostomy?

An ostomy is a surgically created opening in the abdomen that allows stool or urine to exit the body when natural function is impaired. The three main types are colostomy, ileostomy, and urostomy. Ostomies may be temporary or permanent depending on medical need. This page explains how ostomies work, why they’re performed, what recovery looks like, and how people live full lives with an ostomy.

An Ostomy

Causes a change in the way urine or stool exits the body as a result of a surgical procedure. Bodily waste is rerouted from its usual path because of malfunctioning parts of the urinary or digestive system. An ostomy can be temporary or permanent.

A Stoma

The opening created by ostomy surgery. It is located on the abdomen and is dark pink in color. For most ostomies, a pouch is worn over the stoma to collect stool or urine. For some people it is possible to have a continent diversion,  an alternative to a conventional ostomy that eliminates the necessity for a pouch.

What is Ostomy Surgery?

Ostomy surgery is a life-saving procedure that allows bodily waste to pass through a surgically created stoma on the abdomen into a prosthetic known as a ‘pouch’ or ‘ostomy bag’ on the outside of the body or an internal surgically created pouch for continent diversion surgeries. An ostomy may be necessary due to birth defects, cancer, inflammatory bowel disease, diverticulitis, incontinence and many other medical conditions. They are also necessary in cases of severe abdominal or pelvic trauma resulting from accidents or from injuries sustained during military service.

Ostomy or continent diversion surgery can occur at any age and does not lower life expectancy but is the start of a “new normal” life.

Types of Ostomies

The most common specific types of ostomies are described below. Click for more info.

Colostomy

The surgically created opening of the colon (large intestine) which results in a stoma. A colostomy is created when a portion of the colon or the rectum is removed and the remaining colon is brought to the abdominal wall. It may further be defined by the portion of the colon involved and/or its permanence.

Urostomy

This is a general term for a surgical procedure which diverts urine away from a diseased or defective bladder. The ileal or cecal conduit procedures are the most common urostomies. Either a section at the end of the small bowel (ileum) or at the beginning of the large intestine (cecum) is surgically removed and relocated as a passageway (conduit) for urine to pass from the kidneys to the outside of the body through a stoma. It may include removal of the diseased bladder.

Ileostomy

A surgically created opening from the ileum, the lowest part of the small intestine. The intestine is brought through the abdominal wall to form a stoma. Ileostomies may be temporary or permanent, and may involve removal of all or part of the colon.

Continent Urostomy

There are two main continent procedure alternatives to the ileal or cecal conduit (others exist). In both the Indiana and Kock pouch versions, a reservoir or pouch is created inside the abdomen using a portion of either the small or large bowel. A valve is constructed in the pouch and a stoma is brought through the abdominal wall. A catheter or tube is inserted several times daily to drain urine from the reservoir.

J-Pouch

A surgically created (J-shaped) internal reservoir made from an individual’s own small intestine as an alternate way to store and pass stool. The ileal pouch anal anastomosis (IPAA) surgery is the most common pelvic pouch (see also, S, W, Kock pouch) surgery performed and most typically used to treat those with ulcerative colitis and inherited conditions such as familial adenomatous polyposis (FAP). J-Pouch creation is most often a multi-step surgery that requires a temporary ileostomy (stoma) on the abdomen and the use of an external pouching system to eliminate waste. When successful the stoma is reversed and patients return to expelling waste through the anus. Talk to your doctor about the benefits and serious risks of this surgery.

Frequently Asked Questions About Ostomies

Clear, trusted answers to the most common questions from new and experienced ostomy patients.

An ostomy is a surgically created opening in the abdomen that allows stool or urine to leave the body when the usual route is not safe or no longer works. The opening is called a stoma and it may be needed because of disease, injury, or other medical conditions.

An ostomy may be done for conditions such as colorectal or bladder cancer, inflammatory bowel disease (Crohn’s disease or ulcerative colitis), diverticulitis, birth defects, severe infection, or traumatic injury to the bowel or bladder. In these situations, an ostomy can protect healing tissues, prevent complications, and be a life-saving surgery.

No. Some ostomies are temporary and are reversed once the bowel or urinary tract has healed, while others are permanent because the affected organ has been removed or cannot safely be reconnected. Your surgeon will explain whether your ostomy is intended to be temporary or permanent and why.

The three most common ostomies are colostomy, ileostomy, and urostomy. A colostomy diverts stool from the large intestine, an ileostomy diverts stool from the small intestine, and a urostomy diverts urine when the bladder has been removed or bypassed. Each type is created for different conditions and has specific care needs.

Yes. People with ostomies work, travel, exercise, swim, play sports, and have relationships. Once recovery is complete and the right pouching system is found, most people return to an active daily life with family, friends, and work. Check out our Ostomy Mythbusters infographic  – Facts and Truth to Fight Ostomy Stigma.

In the United States, it is estimated that approximately 725,000 to 1,000,000 people are living with an ostomy, and about 100,000 ostomy surgeries are performed each year. This means you are far from alone, even if you may not realize how many others have an ostomy.
