Bladder Augmentation (Ileal or Ileocaecal)

What is Bladder Augmentation (Ileal or Ileocaecal)?

Bladder augmentation, also known as augmentation cystoplasty, is a reconstructive surgical procedure used to increase the size and capacity of the bladder. During the operation, a segment of the small intestine, either the ileum (ileal augmentation) or the ileocaecal segment (ileocaecal augmentation), is used to enlarge the bladder.

The procedure is performed when the bladder is too small, stiff, or overactive to store urine safely. By increasing bladder capacity and reducing bladder pressure, augmentation cystoplasty can improve urinary continence, protect kidney function, and enhance quality of life in carefully selected patients.

What are the Benefits of Bladder Augmentation (Ileal or Ileocaecal)?

For appropriate candidates, bladder augmentation can provide significant long-term improvements in bladder function.

Benefits include:

  • Increases bladder capacity
  • Lowers bladder storage pressure
  • Improves urinary continence
  • Protects kidney function from high bladder pressures
  • Reduces urinary urgency and frequency
  • Improves quality of life
  • May reduce the need for long-term urinary drainage
  • Can be combined with other reconstructive urological procedures when required

When is Bladder Augmentation (Ileal or Ileocaecal) Recommended?

Bladder augmentation is generally reserved for patients with severe bladder dysfunction that has not responded to conservative treatments.

It may be recommended for:

  • Neurogenic bladder caused by spinal cord injury, spina bifida, or multiple sclerosis
  • Severe overactive bladder resistant to medication and other therapies
  • Small, contracted bladder following chronic inflammation or previous treatment
  • Bladder damage resulting from pelvic radiotherapy
  • Congenital bladder abnormalities
  • Poor bladder compliance causing kidney damage
  • Selected complex reconstructive urological conditions

The procedure is considered only after less invasive treatment options have been fully explored.

What does Preparation for Bladder Augmentation Involve?

Before surgery, your urologist will perform a detailed assessment of your bladder function and overall health.

Preparation may include:

  • Comprehensive medical history and physical examination
  • Blood and urine tests
  • Kidney function assessment
  • Ultrasound or CT imaging of the urinary tract
  • Urodynamic studies to assess bladder pressure and capacity
  • Cystoscopy to examine the bladder lining
  • Review of medications
  • Bowel preparation if required
  • Discussion of the procedure, expected outcomes, long-term follow-up, and potential need for intermittent self-catheterisation

Patients will also receive counselling regarding lifestyle changes and the long-term care required after bladder reconstruction.

How is Bladder Augmentation Performed?

Bladder augmentation is performed under general anaesthetic and usually takes several hours.

The surgeon first makes an incision using either an open or, in selected cases, a minimally invasive approach. A carefully measured section of the small intestine is then isolated while preserving its blood supply. Depending on the patient's anatomy and clinical requirements, either a segment of the ileum or the ileocaecal region is used.

The bowel segment is opened and reshaped into a patch to create a larger reservoir. The bladder is then opened, and the intestinal patch is carefully stitched to the bladder, significantly increasing its capacity while reducing storage pressure. The remaining bowel is reconnected to restore normal intestinal continuity.

A urinary catheter is left in place to allow the bladder to heal, and temporary drains may also be inserted. In some patients, a continent catheterisable channel, such as a Mitrofanoff, may be created during the same operation if catheterisation through the urethra is difficult.

Following surgery, the enlarged bladder gradually adapts to its new capacity over several weeks.

What to Expect during Recovery after Bladder Augmentation?

Recovery following bladder augmentation is longer than with many other urological procedures.

During recovery, patients can expect:

  • A hospital stay of approximately one to two weeks
  • Urinary catheter drainage for several weeks
  • Temporary surgical drains
  • Gradual return to eating as bowel function recovers
  • Mild to moderate abdominal discomfort controlled with pain medication
  • Regular bladder irrigation to remove mucus produced by the bowel segment
  • Follow-up imaging before catheter removal

Many patients require clean intermittent self-catheterisation after surgery to ensure complete bladder emptying. Long-term follow-up is essential to monitor bladder function, kidney health, and potential complications.

What are the Risks and Complications of Bladder Augmentation?

Bladder augmentation is a complex reconstructive procedure and carries the risks associated with major surgery.

Possible complications include:

  • Bleeding
  • Infection
  • Urinary tract infections
  • Leakage from the bladder reconstruction
  • Bowel obstruction
  • Blood clots
  • Excess mucus production within the bladder
  • Difficulty emptying the bladder requiring intermittent self-catheterisation
  • Bladder stones
  • Metabolic disturbances caused by absorption through the bowel segment
  • Rare long-term risk of malignancy developing within the augmented bladder
  • Need for future revision surgery

Your urologist will explain whether bladder augmentation is the most appropriate treatment for your condition, discuss the expected benefits and potential risks, and provide detailed guidance on the lifelong follow-up required after this reconstructive procedure.
