Ureterostomy: Understanding the Surgical Procedure for Urinary Diversion

Your body's process of eliminating urine is something we often take for granted, isn't it? Urine, produced by the kidneys, travels down tubes called ureters, collects in the bladder, and is expelled when needed. But what happens if your bladder stops working correctly, or needs to be removed entirely? The body loses its natural pathway for urine elimination. This is where a specialized surgical procedure comes into play – one that offers a vital solution.

What Exactly is Ureterostomy?

In simple terms, Ureterostomy (යූරිටරොස්ටොමි) is a surgical procedure where the ureters – the tubes carrying urine from your kidneys to your bladder – are disconnected from the bladder and instead connected to a small opening created on the surface of your abdomen. This newly created opening is called a stoma (ස්ටෝමා).

Think of it like this: Imagine two pipes feeding water into a tank. Now, suppose the tank is broken or needs to be removed. The solution would be to disconnect the pipes from the tank and direct them straight out. In ureterostomy, the bladder (the 'tank') is bypassed, and the ureters ('pipes') are rerouted directly through the stoma to the outside of the body.

After the surgery, urine flows directly from the kidneys, through the ureters, and out of the body via the stoma. To collect this urine, a special plastic bag, known as a pouch (පෞච්), is attached around the stoma. You'll need to empty this pouch regularly, typically as often as you would normally urinate. For infants, the urine can be collected into a diaper.

The primary goal of this surgery is to create a reliable way for urine to exit the body safely when the bladder is no longer functional. Often, this is a permanent procedure.

Who Needs This Surgery?

Your doctor might recommend ureterostomy if your bladder cannot function normally to store or expel urine. Several reasons can lead to this situation:

Reason	Simple Explanation
Bladder Removal	The bladder needs to be completely removed due to cancer or another disease.
Bladder Damage	Severe injury from an accident or other causes has damaged the bladder beyond repair.
Congenital Conditions	Certain conditions present at birth, like Spina Bifida, prevent the bladder from working correctly.
Spinal Cord Injury	Damage to the spinal cord impairs the ability to control bladder function.

Pre-Surgical Preparations

Before the surgery, your doctor will order several tests to thoroughly assess your condition:

• Kidney Function Tests: To evaluate how well your kidneys are working.
• Blood Tests: To check your overall health status.
• Imaging Tests (X-ray, Ultrasound): To visualize the kidneys and urinary tract.
• Retrograde Pyelogram: A special dye is injected into the ureters, and X-rays are taken to map the urinary system.
• CT Scan or MRI: These provide detailed cross-sectional images of the body for a clearer picture.

Additionally, your surgical team will discuss the best location for the stoma with you. This is typically chosen to be easily visible, avoid clothing belts, and be on a relatively flat area of skin free from wrinkles.

The Surgery and How the System Works

During the surgery, the surgeon disconnects one or both ureters from the bladder and connects them to the newly created stoma on your abdomen. Urine no longer enters the bladder.

Here's how the new system functions:

Unlike the natural urinary tract, the stoma does not have a sphincter muscle to control urine flow. Therefore, urine will continuously drain from the kidneys through the ureters and out of the stoma.

Urine collection involves these steps:

1. Attaching the Pouch: A pouching system consists of two parts: a skin barrier that adheres to the abdomen around the stoma, and a collecting pouch attached to the barrier. Some systems combine both into one piece.
2. The Skin Barrier: This is typically a square-shaped adhesive with a hole cut to fit the stoma. It sticks securely to the skin, preventing urine leakage.
3. The Collecting Pouch: This bag attaches to the barrier and collects the urine draining from the stoma.

You'll need to empty the pouch when it's about one-third to half full. Most pouches have a small valve at the bottom, allowing you to drain the urine into a toilet without removing the entire pouch. At night, you can connect a longer tube to the valve and attach it to a larger drainage bag.

The pouch is usually worn under clothing and is not visible.

Stoma and Pouch Care

After surgery, your doctor or nurse will provide detailed instructions on caring for your stoma, the surrounding skin, and the pouch. Proper hygiene is crucial.

Daily care includes:

• Gently cleaning the stoma and surrounding skin with mild soap and water.
• Rinsing thoroughly and patting dry.
• Changing the pouch regularly, typically every 5 to 7 days, or sooner if it leaks or becomes soiled.

Maintaining a clean and dry stoma area is extremely important to prevent skin irritation and infection.

Potential Risks and Complications

Like any surgery, ureterostomy carries potential risks. Discuss these thoroughly with your doctor beforehand:

• Infection
• Bleeding
• Hernia development
• Skin irritation or allergic reactions around the stoma
• Failure to achieve the desired outcome
• Scar tissue formation

When to Contact Your Doctor

Monitor your stoma and surrounding skin closely. Contact your doctor immediately if you notice:

• Redness, rash, or blisters on the skin around the stoma.
• Skin breakdown or sores.
• Changes in urine appearance (dark color, blood, excessive foam) or odor.
• Signs of infection like fever, chills, back pain, nausea, vomiting, or loss of appetite.

Urostomy vs. Nephrostomy vs. Ureterostomy

These terms describe different types of urinary diversion surgeries:

• Urostomy: This is a general term for any surgery that creates an opening (stoma) to divert urine away from the bladder. Ureterostomy is one type of urostomy. Other forms might involve using a segment of bowel to create a conduit.
• Nephrostomy: In this procedure, a tube (catheter) is inserted directly into the kidney to drain urine into an external bag. This is often used when the ureters are blocked and may be temporary.
• Ureterostomy: As described above, this specifically involves connecting the ureters directly to a stoma on the abdominal wall.

Living After Surgery

Adjusting to life after ureterostomy can take time. It's normal to feel emotional about not being able to urinate in the conventional way. Talk openly with your doctor or a counselor; they can provide support and resources.

Remember, you are not alone. Many people have successfully adapted to living with a stoma. Focus on the fact that this surgery enables you to live a healthier, longer life.

Key Takeaways

• Ureterostomy reroutes urine from the kidneys directly through a stoma on the abdomen, bypassing the bladder.
• It's often necessary when the bladder is removed or non-functional due to cancer, injury, or congenital issues.
• A pouch worn over the stoma collects urine, which needs regular emptying and changing.
• Keeping the stoma and surrounding skin clean and dry is vital.
• Be vigilant for signs of complications like skin irritation, infection, or changes in urine, and contact your doctor promptly.
