A urostomy may seem daunting because of perceptions on how it changes one’s lifestyle, but proper management can go a long way to helping people live fruitful lives with a stoma. If you are scheduled to undergo a urostomy soon but are not sure what it entails, this guide should help clarify your doubts and concerns. What is a Urostomy? A urostomy is a type of ostomy surgery in which an opening (called a stoma) is temporarily or permanently created in your abdomen to allow your body to remove urine. It is typically performed when the urinary tract cannot function properly, often due to a medical condition that requires removal of parts of the urinary system (such as the bladder). A urostomy diverts urine to be excreted through the stoma instead of through the urinary tract. A small segment of the small intestine (the ileum) is used to create a tube connecting the stoma to the ureters. The procedure will also involve carefully separating the functional parts of your digestive or urinary tract from the problematic parts. The excreted waste is then collected in a bag or pouch attached to the stoma. Living with a urostomy takes time to get used to, but once you become familiar with the proper care of your stoma, it will barely interfere with your usual daily routine. Types of Urostomies There are two primary types of urostomy procedures: incontinent and continent urostomies. Incontinent Urostomy An ileostomy diverts a part of the small intestine (ileum) to the abdominal wall as a stoma. Because the output tends to be more liquid-like, ileostomy bags are primarily designed to hold larger volumes of semi-solid or liquid output. An ileostomy bag is made of a soft, flexible, and durable material that helps prevent leaks over long periods, while the adhesive seal connecting the stoma to the wafer is also stronger, providing more secure bag placement and handling. High-output ileostomy bags are also available, allowing people with high-output stomas to have more peace of mind on busy days. Continent Urostomy A continent urostomy involves creating a new bladder-like pouch using a portion of your small or large intestine to hold urine without needing an external appliance. The urine is removed either by emptying into the urethra and being expelled as usual, or by a catheterising pouch that allows regular drainage via a catheter. Why Would You Need a Urostomy? Your urinary system comprises both kidneys, a pair of ureters that connect the kidneys to the bladder, and a urethra that expels the urine. The kidneys produce urine by filtering water and waste products from your bloodstream, then draining it through the ureters into the bladder. Urine is subsequently removed from the body through the urethra. When any part of the urinary system fails for various reasons (such as bladder cancer), a urostomy allows urine to be diverted from the urinary system and drained through the stoma. In doing so, it prevents urine from accumulating in the body, which could cause further (and more chronic) health complications. Some of the more common reasons a person may need a urostomy include: Bladder cancer Trauma to the bladder or urethra Urinary incontinence Nerve damage affecting bladder control Other spinal injuries or conditions Urinary abnormalities What to Expect After a Urostomy A urostomy is an involved surgical procedure that may require the removal of part or all of your bladder (or other parts of the urinary system). Urine may start flowing from the stoma a few days after surgery and may initially appear slightly pink or red. It should not be long before urine returns to its usual colour. Since the small intestine produces mucous as part of its digestive role, you may notice some mucous in your urine while excreting it. Once you begin the recovery phase, not long after surgery, your stoma care nurse or doctor will teach you how to use your ostomy pouch and care for your stoma. Stoma Care A healthy stoma should appear moist and reddish or pinkish, protruding from your lower abdomen. The stoma may initially appear swollen after surgery, but it will gradually shrink after several weeks. You may notice some bleeding when cleaning your stoma, but it should subside over time. When the output first comes out of the stoma, it will be strong-smelling and watery. This is normal, as your bowels have not been functioning properly since the surgery, so the output’s appearance will gradually normalise once you begin taking a balanced diet per your doctor’s instructions. Note that it may take some time before you can eat and drink as usual. To care for your stoma, be sure to follow these instructions: Wash your hands with soap and water before checking your stoma. Check your stoma often to detect and treat problems early. Gently clean the stoma to prevent excessive bleeding. Avoid applying any oils, creams, or powders around the stoma. Regularly shave the hair around your stoma to prevent inflammation of the hair follicles. Ensure the skin barrier is cut to fit your stoma properly, with no gaps that could cause a leak. Ensure the stoma area is dry before applying the urostomy pouch’s skin barrier. If you experience irritation or other issues around the stoma area, remove the urostomy pouch and look for signs of a leak. Clean the stoma area thoroughly and replace the urostomy bag. Urostomy Pouch Urostomy pouches are waterproof and odour-proof, preventing leakage of stoma output for several hours. These pouches are available as part of one-piece or two-piece systems: one-piece systems combine the pouch and skin barrier, while two-piece systems feature a skin barrier and a separate attachable pouch. One-piece systems are generally more convenient to use, while two-piece systems are more versatile and reduce skin irritation from frequent skin barrier changes. You will still need to change the pouch regularly to maintain your hygiene and prevent complications. Your choice of urostomy pouch will largely depend on the size and shape of your stoma, so
