Bladder exstrophy is a rare congenital condition in which a baby is born with the bladder located outside the body. It occurs when the bladder and lower abdominal wall do not close properly during fetal development. Bladder exstrophy affects the urinary system, pelvic bones, and surrounding structures and usually requires specialized surgical care shortly after birth.
Bladder exstrophy is a rare congenital condition in which a baby is born with the bladder located outside of the body. During normal fetal development, the lower abdominal wall and bladder close and form inside the pelvis. In bladder exstrophy, this closure does not occur completely, leaving the bladder open and exposed on the surface of the abdomen.
Because the bladder is not enclosed within the body, urine cannot be stored normally. The condition also affects surrounding structures including the pelvic bones, abdominal muscles, and reproductive organs. Bladder exstrophy is part of a broader group of conditions known as the exstrophy–epispadias complex (EEC).
Bladder exstrophy occurs in approximately 1 in 30,000 to 50,000 births worldwide, and it is slightly more common in boys than girls. Although the condition is rare, advances in pediatric urology and surgical care have dramatically improved outcomes. Many individuals born with bladder exstrophy go on to lead full, active lives with appropriate medical care and long-term support.
Understanding the condition, available treatments, and the resources available for families is an important first step after diagnosis.
Bladder exstrophy affects multiple systems in the body because it develops early during fetal growth. In addition to the bladder being exposed outside the abdomen, the condition influences how nearby structures form and function. Because multiple structures are involved, treatment for bladder exstrophy typically requires specialized surgical care and ongoing medical follow-up.
Common areas affected include:
Children born with bladder exstrophy have several anatomical differences that are important for doctors to understand when planning treatment.
These differences may include:
These anatomical characteristics are part of the exstrophy–epispadias spectrum, and they help guide the surgical approach used to repair the bladder and restore urinary function.
Bladder exstrophy is considered a rare congenital condition. It occurs in approximately 1 in 30,000 to 50,000 live births worldwide. Because of its rarity, many families have never heard of bladder exstrophy before receiving a diagnosis.
The condition is slightly more common in males than females, although it can affect children of any sex. Bladder exstrophy also occurs across all geographic regions and ethnic groups.
Although the condition is uncommon, advances in pediatric urology and surgical care have significantly improved outcomes. Many children born with bladder exstrophy grow up to live active and fulfilling lives with appropriate medical treatment and long-term care.
Because bladder exstrophy is rare, families often benefit from working with specialized medical centers and support organizations that have experience treating the condition.
To learn more about the different forms of the condition, see Types of Bladder Exstrophy Conditions below.
Bladder exstrophy belongs to a group of related conditions known as the exstrophy–epispadias complex (EEC). These conditions vary in severity and involve differences in how the urinary and reproductive systems develop.
The three primary conditions in this spectrum include classic bladder exstrophy, epispadias, and cloacal exstrophy.
Classic bladder exstrophy is the most commonly recognized form of the condition. In this form, the bladder is open and exposed on the abdominal wall at birth.
Children with classic bladder exstrophy often have:
Treatment typically involves surgical repair of the bladder and surrounding structures, often beginning shortly after birth.
Epispadias is a related condition that affects the urethra. In epispadias, the urethra does not form normally and opens on the upper surface of the genitalia rather than at the tip.
Epispadias can occur on its own or as part of bladder exstrophy. When it occurs alone, it may cause difficulties with urinary control and may require surgical correction.
Because epispadias and bladder exstrophy share developmental origins, they are considered part of the same condition spectrum.
Cloacal exstrophy is the most severe form of the exstrophy–epispadias complex. It involves multiple systems of the body, including the urinary tract, intestines, and reproductive organs.
This condition is often referred to as OEIS complex, which stands for:
Bladder exstrophy is typically visible at birth because the bladder is exposed on the abdomen. However, the condition can also involve a range of symptoms related to the urinary system, pelvic anatomy, and reproductive organs.
Some individuals may experience urinary control challenges, bladder function differences, or other related conditions. To learn more about the signs and symptoms associated with bladder exstrophy, visit our detailed guide on Bladder Exstrophy Symptoms.
Bladder exstrophy can often be diagnosed before birth during a routine prenatal ultrasound. Doctors may notice that the bladder does not appear normally within the abdomen, prompting further evaluation. In other cases, the condition is diagnosed immediately after birth because the bladder is visibly exposed. A pediatric urologist or specialized medical team typically performs additional examinations to confirm the diagnosis and develop a treatment plan.

Treatment for bladder exstrophy focuses on reconstructing the bladder, protecting kidney function, and improving urinary control. Surgical repair is the primary approach used to treat the condition. Treatment plans vary depending on the child’s anatomy and the medical center providing care.
In some cases, surgeons perform a primary repair of bladder exstrophy (CPRE) shortly after birth. This procedure closes the bladder and abdominal wall and reconstructs the urinary tract.
The goal of primary repair is to place the bladder inside the body and create the foundation for normal bladder growth and function.
In some cases, surgeons perform a primary repair of bladder exstrophy (CPRE) shortly after birth. This procedure closes the bladder and abdominal wall and reconstructs the urinary tract.
Another approach involves staged surgical repair, where reconstruction is performed through a series of procedures over time.
This approach may include:
Both surgical approaches aim to help children achieve the best possible urinary function and quality of life.
Children born with bladder exstrophy typically receive care from a multidisciplinary medical team with experience treating complex urinary conditions. Because the condition affects multiple parts of the body, treatment often involves several specialists working together to support the child’s health and development.
The care team may include:
Many families choose to work with Centers of Excellence or hospitals that specialize in bladder exstrophy treatment, where experienced teams are familiar with the unique needs of children born with this condition.
Bladder exstrophy can affect several aspects of a child’s development and daily life, particularly during early childhood and school years. Because the condition involves the urinary system, pelvic anatomy, and sometimes additional surgeries, children may experience medical, social, and emotional challenges as they grow.
Every child’s experience is different. Many children with bladder exstrophy grow up to lead active and healthy lives, especially when they receive specialized care and support from experienced medical teams.
One of the primary goals of treatment is to improve bladder function and urinary continence. Children with bladder exstrophy may require multiple surgeries to help the bladder store urine effectively and protect kidney health. Over time, many individuals achieve improved urinary control, although some may continue to use additional medical strategies to manage bladder function.
Most children with bladder exstrophy are able to participate in normal childhood activities, including sports, school events, and social activities. After surgical recovery, many children can be physically active and enjoy the same types of play and exercise as their peers.
Doctors may provide guidance about recovery periods after surgeries and how to safely return to activities.
Growing up with a rare medical condition can sometimes bring emotional or social challenges. Children may have questions about their bodies, medical care, or differences they notice compared to other children.
Support from family members, healthcare providers, and community organizations can help children build confidence and develop a positive sense of identity as they grow.
Bladder exstrophy is a lifelong condition that requires ongoing medical follow-up. As children grow into adulthood, care may transition from pediatric specialists to adult urology providers who are familiar with the condition.
Long-term care focuses on maintaining bladder health, protecting kidney function, and supporting overall quality of life.
The exact cause of bladder exstrophy is not fully understood. Researchers believe the condition occurs early during fetal development when the structures of the lower abdominal wall and bladder do not close properly.
Most cases occur randomly and are not linked to actions taken during pregnancy. However, ongoing research continues to explore possible genetic and developmental factors that may contribute to the condition. Learn more about the potential causes and risk factors in our Bladder Exstrophy Causes guide.
Although bladder exstrophy is a complex congenital condition, many individuals grow up to live active, fulfilling lives. Advances in pediatric urology, reconstructive surgery, and long-term care have significantly improved outcomes for children born with this condition.
Living with bladder exstrophy often involves ongoing medical care and follow-up, particularly during childhood and adolescence. However, with appropriate treatment and support, many children participate fully in school, sports, and social activities.
Because the condition affects the urinary system and pelvic anatomy, some individuals may require additional procedures or specialized care as they grow. Long-term follow-up helps ensure bladder health, kidney protection, and overall well-being throughout childhood and adulthood.
Children with bladder exstrophy often attend school, participate in activities, and develop friendships just like their peers. Families may work with healthcare providers and school staff to ensure appropriate support when needed, particularly during recovery from surgeries or when managing bladder care.
Many families find that open communication and supportive school environments help children build confidence and independence.
As children grow into adolescence, medical care may gradually transition from pediatric specialists to adult healthcare providers familiar with bladder exstrophy. This transition helps ensure continuity of care and supports long-term health.
Adolescence can also bring questions related to body image, independence, and future health planning. Healthcare teams and support organizations can help guide families through these stages.
Adults with bladder exstrophy may continue to see urologists who specialize in long-term bladder health. Ongoing care focuses on maintaining kidney function, bladder health, and overall quality of life.
Many adults with bladder exstrophy pursue education, careers, relationships, and families of their own. Access to knowledgeable medical providers and supportive communities can make an important difference throughout adulthood.
A diagnosis of bladder exstrophy can feel overwhelming for families, especially when it is unexpected. Access to reliable information and supportive communities can make a significant difference during this time.
A-BE-C works to provide education, resources, and connections for families and individuals affected by bladder exstrophy. Through conferences, educational programs, and community support, families can find guidance and reassurance from others who understand the journey.
Support networks, medical experts, and educational resources can help families navigate each stage of care.
If you or your child has been diagnosed with bladder exstrophy, learning about the condition and available treatment options is an important first step.
