Congenital exstrophy of the urinary bladder is a birth defect. The lower belly wall does not close in the middle during early pregnancy. The front of the bladder also stays open. At birth, the inside of the bladder is visible on the outside of the baby’s lower belly. The urethra, genitals, pelvic bones, and pelvic floor muscles can also be affected. Doctors call this group of problems the exstrophy-epispadias complex (EEC). Bladder exstrophy is rare. It needs careful care from pediatric urology teams. Surgery is used to close the bladder and the belly wall and to help the child gain urine control later in life. With expert care and follow-up, many children do well. NCBI+2PMC+2
Bladder exstrophy is a birth defect where the bladder and nearby tissues do not close inside the lower belly during fetal growth, so the bladder plate is exposed on the outside at birth. It is part of a spectrum called the exstrophy-epispadias complex (EEC), which ranges from isolated epispadias (milder) to cloacal exstrophy (more severe). Children need staged or complete primary surgery to place the bladder inside, close the abdomen, and build urinary control. Lifelong follow-up is common to protect kidneys, support continence, sexual function, and quality of life. The exact cause is not fully known. Incidence is rare. auanews.net+3NCBI+3rarediseases.info.nih.gov+3
During early pregnancy, the lower abdominal wall and bladder should close. In exstrophy, failure of that closure leaves the bladder open; pubic bones are wide apart and genitals may be affected (often with epispadias). Because the bladder cannot store urine, babies leak urine constantly until repaired. Protection of the exposed bladder, skin care, and early specialist transfer are important before surgery. NCBI+1
Other names
Bladder exstrophy is also called: exstrophy of the bladder, exstrophy-epispadias complex (when epispadias is present), classic bladder exstrophy (to distinguish from cloacal exstrophy, a more severe form), and ventral body wall defect involving the bladder. These names describe the same core problem: the bladder and front belly wall did not close properly before birth. NCBI+1
Types
Doctors place bladder exstrophy within a spectrum:
Isolated epispadias – the urethral opening is on the top side of the penis in boys or displaced in girls; the bladder may be intact. This is the mild end of the spectrum. NCBI
Classic bladder exstrophy – the bladder plate (inner bladder surface) lies open on the lower abdomen; there is usually a wide gap between the pubic bones, changes in the belly wall, urethra, and genitals. This is the typical form. NCBI
Cloacal exstrophy – the most severe form; the lower abdominal wall is open, and the intestines and bladder are split and exposed; there are often spinal and anal anomalies. Jpurol
Causes
The exact single cause is not known. Most experts think several early developmental steps go wrong together. Below are 20 contributing factors and mechanisms that have been discussed in the medical literature. Each item is a possible contributor, not a proven cause in every child.
Early failure of the lower belly wall to close – the tissue that should meet in the middle does not seal, leaving a gap. NCBI
Abnormal cloacal membrane – an unusually large or persistent membrane may block normal inward growth of muscle and connective tissue, preventing closure. ResearchGate
Poor migration of mesenchymal cells – these cells normally fill the area that becomes the belly wall; if they do not move in, the wall stays weak and open. ScienceDirect
Early rupture of the cloacal membrane – if the membrane breaks too soon (around week 7), the bladder and lower wall can open outward. Lippincott Journals
Timing mismatch between membrane rupture and pelvic development – a small shift in timing can change the final shape of the pelvis and bladder. ScienceDirect
Genetic susceptibility – most cases are sporadic, but family clustering suggests some genetic risk factors. PMC
Sex-linked differences – rates are higher in males than females, hinting at biologic susceptibility by sex. PMC
Environmental influences during early pregnancy – specific agents are not proven, but many congenital defects reflect combined genetic-environmental effects. (Epidemiology papers discuss multifactorial risk without pinning down a single toxin.) PMC
Abnormal pelvic floor muscle formation – the muscles that support the bladder and urethra may not form or align, leading to poor support. NCBI
Pubic bone diastasis – the pubic bones do not meet; the pelvis stays wide and open; this both reflects and worsens the defect. NCBI
Urethral development errors (epispadias) – the urethra opens on the top side in boys or is split in girls, often accompanying bladder exstrophy. NCBI
Malrotation/malposition of the bladder – the bladder can be pulled outward as the body wall fails to close. NCBI
Abnormal umbilical position – a low-set umbilicus is a clue to a broader midline closure problem. PubMed
Associated spinal anomalies – the spectrum sometimes includes spinal or sacral differences that share early developmental timing. NCBI
Abnormal genital tubercle development – affects penile or clitoral formation and location of the urethral opening. NCBI
Pelvic ring malalignment – the ring shape of the pelvis never forms tightly; this disrupts support for the bladder outlet. NCBI
Inadequate fetal bladder filling/emptying cycles – a secondary effect that can affect bladder growth and later capacity. PMC
Embryologic “wedge effect” theory – a large cloacal membrane acts like a wedge, stopping the two sides of the body wall from joining. ResearchGate
Multifactorial inheritance – many congenital anomalies arise from several small genetic variants plus environment; this model likely applies here. PMC
Unknown or unmeasured factors – most cases have no clear single trigger, which is common in rare congenital malformations. NCBI
Symptoms and signs
In newborns, the diagnosis is usually obvious by inspection. Later symptoms relate to urine leakage, infections, and pelvic support.
Visible open bladder plate on the lower belly – red, moist tissue at the midline below the umbilicus. This is the hallmark sign at birth. NCBI
Constant urine leakage from the exposed bladder surface – urine drains directly onto the skin. NCBI
Wide gap between pubic bones (pubic diastasis) – the pelvis looks broad; hips may appear turned outward. NCBI
Low-set umbilicus – the belly button sits lower than normal. PubMed
Epispadias – in boys, the urethral opening is on the upper penis; in girls, the urethra may split the clitoris; both can cause leakage. NCBI
Abnormal external genitalia – short or upward-curved penis in boys; separated clitoris and short urethra in girls. NCBI
Weak pelvic floor – poor muscle support can worsen leakage and continence issues later. NCBI
Urinary tract infections (UTIs) – skin exposure and later reconstructive anatomy can increase UTI risk. NCBI
Small bladder capacity – the bladder may be small at first; capacity may grow after staged care. PubMed
Incontinence after infancy – many children need staged reconstruction to improve continence as they grow. NCBI
Skin irritation – constant wetness can cause rashes on belly, thighs, and groin. NCBI
Pelvic/hip alignment issues – gait can be affected in some children due to pelvic diastasis. NCBI
Fertility or sexual function concerns later in life – depends on anatomy, repairs, and gender-specific factors; long-term follow-up is important. PMC
Psychosocial stress – children and families may face body-image, continence, and social challenges; counseling helps. PMC
Associated anomalies – in severe cases (e.g., cloacal exstrophy), there may be spinal, anal, or intestinal issues. Jpurol
Diagnostic tests
Diagnosis at birth is usually clear from the physical exam. Tests help define anatomy, plan surgery, check kidney function, and track growth. I’ve grouped tests into Physical Exam, Bedside/Manual, Lab & Pathology, Electrodiagnostic/Urodynamics, and Imaging.
A) Physical exam
Newborn inspection of the lower abdomen – the doctor looks for an open bladder plate, the low umbilicus, and skin changes. This confirms the diagnosis. NCBI
Genital exam – checks for epispadias, penile length/curvature in boys, clitoral/urethral appearance in girls, and perineal anatomy. This guides surgical planning. NCBI
Pelvic assessment – the clinician evaluates pubic bone gap and hip position. This helps anticipate orthopedic support needs. NCBI
Anal and spinal exam – looks for associated defects, especially when cloacal exstrophy is suspected. Early identification guides referrals. Jpurol
Skin integrity check – prolonged moisture can irritate skin; early protection prevents infection and pain. NCBI
B) Bedside / manual tests
Measurement of pubic diastasis – the distance between pubic bones can be estimated clinically and later measured precisely; large gaps are typical. NCBI
Fetal pubic diastasis measurement on ultrasound (during pregnancy) – if >10 mm later in gestation, this supports prenatal diagnosis. It adds objective evidence before birth. Karger Publishers
Gentle palpation of abdominal wall – checks muscle edges and hernias; helps plan closure. NCBI
Bladder plate observation during care – nurses and doctors watch urine drainage and mucosal health; this guides protective dressings before surgery. NCBI
C) Laboratory & pathology
Urinalysis and urine culture – screens for infection, blood, or protein; repeated tests help track UTIs after repair. NCBI
Serum creatinine and blood urea nitrogen – checks kidney function; important before and after surgeries. NCBI
Electrolytes and acid–base status – monitors hydration and any changes from urinary diversion or reconstruction. NCBI
Pathology of excised tissue (when applicable) – rarely needed for diagnosis, but tissue from surgery may be examined to confirm normal bladder lining and rule out uncommon changes. NCBI
Infection screening in infants with fever – culture-based testing guides antibiotics if a UTI develops. NCBI
D) Electrodiagnostic / urodynamics
Urodynamic studies – later in childhood, tests measure bladder capacity, pressure, and continence after reconstruction to guide next steps. NCBI
Electromyography (EMG) of pelvic floor during urodynamics – shows how pelvic muscles contract and relax; helps tailor continence surgery or therapy. NCBI
Uroflowmetry (when age-appropriate) – measures urine flow pattern after repairs; abnormal curves can signal outlet issues that need attention. NCBI
E) Imaging
Prenatal ultrasound – may show an absent filling bladder, a low umbilicus, a lower abdominal mass, small external genitalia, and pubic diastasis; these signs raise suspicion before birth. PubMed+1
Fetal MRI (selected cases) – adds detail when ultrasound is unclear; helps distinguish bladder from cloacal exstrophy and maps pelvic structures for delivery planning. PubMed+1
Postnatal pelvic/abdominal ultrasound – checks kidneys, ureters, and any swelling; tracks changes after surgery. This is radiation-free and repeatable. NCBI
Pelvic X-ray – shows the pubic bone gap and pelvic alignment; helps time orthopedic or pelvic ring closure with urologic repair. NCBI
Voiding cystourethrogram (VCUG) after reconstruction – outlines the bladder and urethra while voiding to assess reflux, leaks, or outlet narrowing. NCBI
Renal radionuclide scans (when indicated) – evaluates kidney drainage and function if ultrasound or infections suggest a problem. Uroweb
Non-pharmacological treatments (therapies & other measures)

Frequently asked questions
Can exstrophy be seen before birth?
Yes—experienced teams may see it on prenatal ultrasound; planning birth at a center with pediatric urology helps early closure. Mayo ClinicIs there a cure without surgery?
No. Surgery is needed to place the bladder inside and rebuild function; medicines and therapies support continence and kidney safety. CloudFrontWhich repair is “best”: CPRE or staged?
Both are acceptable in trained hands; outcomes depend on center expertise, anatomy, and follow-up. Discuss pros/cons with your surgeon. PubMed+1Will my child be dry (continent)?
Many achieve social continence with reconstruction, bladder training, and sometimes medications or CIC. Individual results vary. CloudFrontHow are kidneys protected?
By keeping bladder pressures low, emptying well (voiding/CIC), preventing UTIs, and regular imaging. Royal Children’s Hospital+1Are anticholinergic drugs safe for kids?
They’re commonly used by specialists with careful dosing and monitoring for side effects like dry mouth and constipation. FDA Access DataIs mirabegron an option if anticholinergics fail?
Sometimes, with blood pressure monitoring and retention precautions; pediatric cautions apply. FDA Access DataCan Botox help?
Yes, in selected refractory cases; patients must be ready for temporary catheterization if retention occurs. FDA Access DataDoes cranberry cure UTIs?
