15846 Augmentation Cystoplasty Bladder Augmentation

Overview

Bladder augmentation — doctors also call it augmentation cystoplasty — is an operation that makes the bladder bigger. It is used when the bladder is small, stiff, or holds urine at a high pressure, so it cannot store urine safely. During the operation, the surgeon takes a small piece of bowel (or, less often, a piece of stomach) and stitches it into the bladder like a patch. The bladder can then hold more urine at a lower pressure. This helps protect the kidneys and can reduce leaking, urgency, and the constant need to go to the toilet. It does not cure the condition that caused the bladder problem, and many people need to use a thin tube called a catheter to empty the bladder afterwards.

It is not common. Bladder augmentation is a specialised operation offered only to a small number of people whose bladder problems have not been helped enough by other treatments.

It is used in both children and adults. The largest groups are people with a bladder that does not work properly because of nerve damage (for example spina bifida, spinal cord injury or multiple sclerosis), people whose bladder has become small and scarred after radiotherapy to the pelvis, people with long-standing bladder pain and inflammation, and people with severe overactive bladder that has not responded to other treatment.

Symptoms

Common symptoms

• Needing to pass urine very often, both day and night
• A sudden, strong urge to urinate that is hard to hold
• Leaking urine before reaching the toilet
• Passing only small amounts of urine at a time because the bladder holds very little
• Repeated urinary tract infections (UTIs)
• Urine flowing back up towards the kidneys, or kidney swelling seen on a scan
• Needing to use a catheter already to empty the bladder
• Feeling that the bladder is never fully empty

Symptoms in children

• Wetting during the day and night that continues well beyond toilet training
• Repeated urine infections
• Poor weight gain or slowed growth
• Swelling of the kidneys seen on an ultrasound scan
• Being born with spina bifida (a condition where the spine does not form completely) or another condition affecting bladder nerves
• Needing to strain or push to pass urine

Symptoms in older adults

• New or worsening incontinence, especially after pelvic surgery or radiotherapy
• Urgency and frequency that disturb sleep and daily life
• Repeated urine infections
• Changes in kidney function picked up on blood tests
• Long-term use of a catheter
• Note: surgery is considered very carefully in older adults, taking other health conditions into account

Causes

Main causes

• Nerve damage affecting the bladder — for example spina bifida, spinal cord injury, multiple sclerosis, or nerve damage from pelvic surgery
• Scarring and shrinkage of the bladder after radiotherapy to the pelvis
• Long-standing bladder inflammation, including bladder pain syndrome (also called interstitial cystitis) and chronic infection such as tuberculosis
• Severe overactive bladder that has not been controlled with other treatments
• Birth conditions such as bladder exstrophy (where the bladder forms outside the body)
• Long-term use of a catheter, which can keep the bladder small and stiff

Risk factors

• Living with a condition that affects the nerves controlling the bladder
• Previous radiotherapy or major surgery in the pelvis
• Repeated urine infections over many years
• Long-term catheter use
• Having had bladder or kidney problems since childhood
• Smoking, which raises the risk of bladder conditions that may lead to this surgery

When to see a doctor

See a doctor urgently if:

• You cannot pass any urine and your lower tummy is painful and swollen
• You have a fever with back pain, shivering, or feel very unwell
• There is blood in your urine
• You have severe abdominal pain with vomiting
• You are passing much less urine than usual and feel unwell

Book a routine appointment if:

• You are leaking urine or rushing to the toilet many times a day and it is affecting your life
• You keep getting urine infections
• You already use a catheter and it is becoming harder to manage
• A scan has shown a problem with your bladder or kidneys
• You would like to talk about whether bladder surgery might be an option for you

Diagnosis

A urology specialist (a doctor who treats bladder and kidney problems) will ask about your symptoms, how often you go to the toilet, your medical history, and any medicines you take. They will want to know how well your bladder stores and empties urine, and how well your kidneys are working. The decision to offer surgery is usually made after a number of tests, often over several appointments, and always after a full discussion of the benefits and risks.

Tests that may be done

• A bladder diary — a record you keep for a few days of how much you drink, how often you pass urine, and any leaks
• Urine tests to look for infection or blood
• Ultrasound scans of the bladder and kidneys
• Urodynamic studies — tests that measure the pressure inside the bladder as it fills and empties
• Cystoscopy — a small camera used to look inside the bladder
• Blood tests, including kidney function
• CT or MRI scans if more detail is needed
• In some cases, an assessment with a specialist continence nurse

What to expect at your appointment

The tests are usually done as outpatient appointments, and some take only a few minutes. Urodynamic tests involve a thin tube being passed into the bladder, which can feel uncomfortable but is usually quick. You will normally have a chance to talk through the results with your surgeon and ask questions before deciding whether to go ahead. A pre-operative assessment will check that you are fit for surgery and for the anaesthetic.

Treatment

Bladder augmentation is one option among several. Treatment usually starts with simpler approaches: changing how much and what you drink, bladder training, timed trips to the toilet, pelvic floor exercises, pads and other containment products, and learning to empty the bladder with a catheter. If these are not enough, doctors may suggest treatments that relax the bladder muscle or injections into the bladder wall. Surgery is considered when the bladder is dangerously high-pressure, the kidneys are at risk, or leaking and urgency are severely affecting daily life.

Self-care at home

• Keep a bladder diary so you and your care team can see patterns
• Drink enough fluid — cutting back too much makes urine more concentrated and can irritate the bladder
• Reduce caffeine and alcohol if you notice they make urgency or leaking worse
• Empty your bladder at planned times rather than waiting for a strong urge
• Treat constipation early, as a full bowel puts pressure on the bladder
• Keep to a healthy weight and stay physically active
• If you use a catheter, follow the cleaning and technique advice from your nurse
• Stop smoking if you smoke, and ask for help to do so

Medical treatments

Doctors may first suggest tablets or patches that calm an overactive bladder muscle, or injections into the bladder wall that relax the muscle for several months at a time. Other options include treatments to reduce nerve signals from the bladder, and help with catheter routines. If these do not work well enough or the kidneys are at risk, surgery may be discussed. Your specialist will explain the choices, what they involve, and their likely benefits and drawbacks for your situation.

When is surgery considered?

Bladder augmentation is offered when other treatments have not controlled the problem and the bladder is small, stiff, or holding urine at high pressure. The operation is done under a general anaesthetic. The surgeon makes a cut in the tummy, detaches a short section of bowel, and uses it as a patch to enlarge the bladder. Sometimes a small channel is also made so a catheter can be passed through the tummy wall. You will have drainage tubes and a catheter afterwards, and you will be taught how to empty your bladder before you go home. Recovery takes several weeks, and heavy lifting and strenuous exercise should be avoided at first. Alternatives such as other types of urinary diversion are also available, and your surgeon will discuss these with you.

Living with this condition

After bladder augmentation, most people settle into a routine of emptying the bladder with a catheter several times a day, either through the urethra (the usual opening) or through a small channel in the tummy. Because the piece of bowel used keeps producing mucus, you will be encouraged to drink plenty of fluids and may need to wash out (irrigate) the bladder to stop mucus building up. Follow-up appointments are a normal part of life afterwards and help catch problems early.

Lifestyle tips

• Build catheter emptying into your daily routine, for example before leaving home and before bed
• Carry spare catheters and supplies with you
• Drink water regularly through the day to keep urine flowing and mucus thin
• Tell your school, workplace, or travel companions what you need so you can empty your bladder comfortably
• Wash your hands before and after catheter use to lower infection risk
• Avoid heavy lifting for the first few weeks after surgery, then build activity back up gradually
• Keep a card or phone note explaining your surgery in case you need medical care elsewhere

Diet and exercise

A balanced diet with plenty of fibre helps prevent constipation, which can put pressure on the bladder. Drinking enough fluid is important, and some people find it helps to limit very sugary drinks, caffeine, and alcohol if they irritate the bladder. Regular gentle exercise supports general health and mood; after surgery, build back up slowly and check with your surgical team before returning to sport or heavy activity. Because part of the bowel is used, your team may check vitamin levels and salt balance from time to time, and may give specific dietary advice for you.

Mental health and emotional wellbeing

It is very understandable if bladder problems, catheters, or the thought of surgery affect your mood, confidence, body image, or relationships. Many people feel anxious before the operation and frustrated during recovery. These feelings are common and worth talking about. If low mood, worry, or distressing thoughts are weighing on you, please reach out to your doctor, a nurse specialist, or a crisis support service in your area — you do not have to cope alone.

Prevention

The operation itself is not something you can prevent — it is a treatment, not a disease. What can sometimes be prevented is the bladder damage that leads to it. Getting bladder problems assessed early, treating urine infections promptly, using catheters carefully, and keeping up with recommended check-ups can all help protect the bladder and kidneys over time.

Screening programmes

After bladder augmentation, long-term monitoring acts as a kind of regular screening. This usually includes periodic check-ups, blood tests, kidney and bladder imaging, and sometimes a camera test of the bladder. These appointments are there to catch stones, infections, salt imbalances, or other problems early. Keeping them, even when you feel well, is one of the most important things you can do.

Complications

If left untreated

• High pressure in the bladder can push urine back towards the kidneys and damage them
• Kidney function may slowly worsen, and in serious cases kidney failure can develop
• Repeated urine infections
• Bladder stones
• Ongoing leaking and urgency that restrict work, travel, sleep, and social life
• Strain on relationships and mental health

Long-term outlook

Most people who have bladder augmentation notice real improvements — fewer leaks, less urgency, and better protection for their kidneys. Recovery takes time, and life afterwards usually involves a catheter routine and regular check-ups, which most people get used to. As with any major operation there are risks, including infection, bowel-related problems, stones, and the need for further procedures, so the decision is made carefully with your specialist team. With good follow-up, many people find they can get back to the activities that matter to them.
