TL;DR
Augmentation cystoplasty, or bladder augmentation, is a surgery that increases the size and capacity of the bladder. A segment of the patient's own intestine is used to expand the bladder wall, which lowers internal pressure and improves urinary continence. It is mainly used for people with neurogenic bladder or a bladder that has lost its ability to stretch. It requires lifelong management, including daily mucus irrigation, but it is highly effective at protecting kidney function and improving quality of life.
Quick Answer — What is augmentation cystoplasty? Augmentation cystoplasty is a surgery that enlarges the bladder using a section of the small or large intestine. It is typically performed for people with neurogenic bladder, such as after a spinal cord injury or with multiple sclerosis, to lower bladder pressure and prevent kidney damage. The operation takes two to six hours and needs a five-to-seven-day hospital stay. Long-term care involves daily irrigation to remove mucus produced by the intestinal segment and, in most cases, ongoing self-catheterization to make sure the bladder empties completely.
Overview of Augmentation Cystoplasty
Augmentation cystoplasty is a reconstructive procedure that expands the storage capacity of the urinary bladder, the hollow, muscular organ that holds urine until it is passed. In some people the bladder becomes spastic, loses its ability to stretch, or develops dangerously high internal pressure. Bladder augmentation addresses these problems by adding a patch of intestinal tissue, usually from the small intestine (ileocystoplasty) or the large intestine (sigmoid or ceco-cystoplasty), to the bladder wall.

Clinical Indications
Surgery is often considered when conservative treatments, such as medication or long-term self-catheterization, are no longer enough to manage bladder symptoms or protect the upper urinary tract. The main goals are reliable urinary continence, less frequent urination, and, most importantly, prevention of kidney infections and permanent kidney damage caused by back pressure.
Condition Category | Common Indications |
Neurogenic bladder | Spinal cord injuries, multiple sclerosis, spina bifida |
Bladder spasticity | Chronic urgency, frequency, and urge-related leakage |
Reduced compliance | Loss of bladder elasticity and capacity |
Kidney protection | High internal bladder pressure threatening kidney function |
The Surgical Procedure
Augmentation cystoplasty is a complex operation that generally lasts between two and six hours. It can be done through a traditional open abdominal incision or with minimally invasive robotic-assisted techniques, depending on the patient's anatomy and the surgeon's recommendation.
Step-by-Step Method
Access: The surgeon reaches the abdominal cavity through the chosen incision method.
Bladder opening: An opening is made at the top of the bladder, often described as a "Pac-Man" style incision, to prepare it for the intestinal patch.
Tissue harvest: A section of small or large intestine is carefully removed and detubularized (cut open) to create a flat piece of tissue.
Augmentation: The intestinal patch is sewn onto the top of the bladder, enlarging its total volume.
Drainage setup: Several tubes and catheters are placed in the bladder and abdomen to allow drainage and irrigation during early healing.

Recovery and Post-Operative Care
Recovery begins with a five-to-seven-day hospital stay. Because the surgery involves the intestines, the bowels often become temporarily paralyzed (ileus). During the first few days, patients are not allowed to eat or drink until bowel function returns.
Hospital Transition
Once the ileus resolves, patients move from clear liquids to solid food, and discharge usually happens about three days after a regular diet is resumed. During the hospital stay, the clinical team gives intensive training on caring for the surgical drains and performing bladder irrigation.
Recovery Milestone | Expected Timeline |
Hospital stay | 5 to 7 days |
Return to solid food | 3 to 5 days after surgery |
Tube removal | Approximately 3 weeks after surgery |
Return to work or school | 6 weeks after surgery |
Full baseline recovery | 3 months after surgery |
Long-Term Management and Safety
A successful augmentation cystoplasty requires a lifelong commitment to specific care routines. Because the bladder is now partly lined with intestinal tissue, it will keep producing mucus, which is a natural function of the bowel.
Mucus Irrigation
This mucus must be flushed out of the bladder every day through irrigation. If it builds up, it can clog catheters, lead to bladder stones, or cause recurrent urinary tract infections (UTIs). In severe cases, a buildup of mucus and urine can overstretch the enlarged bladder or even cause it to tear.
Ongoing Monitoring
Patients also need annual check-ups. These typically include kidney imaging, blood work to check vitamin levels and body chemistry, and renewal of catheter supplies. Most patients continue self-catheterization for life so the bladder is emptied completely and at regular intervals.

Conclusion
Augmentation cystoplasty is a transformative procedure for people with severe bladder dysfunction. By increasing bladder capacity and lowering internal pressure, it offers a lasting improvement in urinary continence and acts as a critical safeguard for kidney health. The surgery requires a significant recovery period and a lifelong commitment to daily irrigation and monitoring, but the gains in quality of life and the protection of vital organs make it a cornerstone of modern urological reconstruction.
Next Steps
If you are considering augmentation cystoplasty, start by discussing your current bladder management routine with your urologist. Ask which intestinal segment would be used and whether a robotic-assisted approach is an option for you. It also helps to speak with a pelvic health specialist or a patient support group to understand the daily realities of mucus irrigation and long-term catheter use. Preparing your home for a six-week recovery, including arranging help with strenuous tasks, will make the transition after surgery smoother.
Frequently Asked Questions
What is augmentation cystoplasty?
It is a surgery that uses a piece of your own intestine to enlarge your bladder.
Who needs this surgery?
It is for people with small, spastic, or high-pressure bladders, often because of nerve damage.
How long does the surgery take?
The procedure typically lasts between two and six hours.
Is the surgery permanent?
Yes. The bladder enlargement from a successful augmentation is permanent.
How long is the hospital stay?
Most patients stay in the hospital for five to seven days.
Can I eat right after surgery?
No. You must wait a few days for your bowel function to return before starting liquids and then solid foods.
What is bladder irrigation?
It is the process of flushing mucus out of the bladder using a saline solution.
Why do I have to irrigate?
The intestinal patch produces mucus that can cause stones or infections if it is not removed.
How often do I need to irrigate?
Most patients irrigate once every morning for the rest of their lives, or as their care team directs.
Will I still need catheters?
Yes. Most people must continue self-catheterization to empty the enlarged bladder completely.
What are the main risks?
Risks include urinary tract infections, bladder stones, and, if the bladder is not emptied properly, the potential for the bladder to tear.
When can I go back to work?
Most people can return to work or school about six weeks after the procedure.
Are there activity restrictions?
Yes. Avoid heavy lifting and strenuous exercise for at least six weeks.
How does this protect my kidneys?
By lowering bladder pressure, it prevents urine from backing up and damaging the kidneys.
Will I need regular follow-ups?
Yes. Annual check-ups with kidney imaging and blood work are required for life.
