Frequently asked questions

Exstrophy of the urinary bladder sequence is a rare birth condition. It starts when a baby is growing in the womb. The lower belly wall does not close. The front wall of the bladder also does not close. After birth, the bladder sits open on the lower belly. The bladder looks like a red, wet plate. It cannot hold urine. Urine leaks all the time. The bones in the front of the pelvis sit too far apart. The belly muscles in the middle are split. The urethra (the tube carrying urine out) is not closed. This problem is part of a group called the exstrophy-epispadias complex. It can be mild or very severe. In severe forms, the intestines and genital organs may also be open.

Doctors can see this at birth. Many times, they can suspect it during pregnancy using ultrasound. Surgery is needed. Surgery closes the belly wall and bladder, protects the kidneys, and helps the child store and pass urine in a more normal way. Often, more than one operation is needed as the child grows. With expert care, many children do well, go to school, play sports, and live active lives. But they may need follow-up for bladder control, kidney health, sexual health, and fertility as they become adults. NCBI+2BioMed Central+2

Exstrophy of the bladder sequence is a rare birth condition where a baby’s lower belly wall and bladder do not close before birth. The inside of the bladder opens on the belly, the pubic bones sit farther apart, and the urethra and genitals may be split or positioned differently (epispadias). Doctors call the whole spectrum the exstrophy–epispadias complex. It needs careful surgery and long-term follow-up to protect the kidneys, help urine control, and support healthy growth. BioMed Central+1

Exstrophy is rare worldwide. It comes from early problems in how the lower belly wall and bladder close during development in the womb. Many babies have no known cause, but studies suggest possible links with parental age, maternal smoking, high maternal body mass index, and sometimes assisted reproduction; genetics likely plays a role, but no single gene explains it. BJUI+3PMC+3PMC+3

Other names

Bladder exstrophy
Classic bladder exstrophy (when the bladder plate is open on the belly)
Exstrophy-epispadias complex (EEC or BEEC) (a spectrum from simple epispadias to cloacal exstrophy)
Cloacal exstrophy (the most severe end of the spectrum, with bowel and bladder both open)
Epispadias (an open urethral tube on the top side of the penis in boys or displaced opening in girls; often part of the spectrum) NCBI+3PMC+3Orpha+3

Types

Isolated epispadias – the urethra opens on the top surface and bladder control may be weak. The bladder itself is usually inside the body. NCBI
Classic bladder exstrophy – the bladder is open on the lower belly; pubic bones are separated; belly wall is split; epispadias is usually present. Orpha
Cloacal exstrophy – the most severe type; both bladder and intestines are open; there may be an omphalocele (sac at the umbilicus), spinal issues, and an imperforate anus. PMC
Exstrophy variants – partial or duplicate bladders, superior vesical fistula, covered exstrophy (skin covers it but structures are abnormal). These are uncommon forms. BioMed Central

Causes

Exstrophy does not happen because of anything the parents did. The exact cause is not fully known. Most experts think several small factors add up early in fetal growth.

Early belly wall closure problem – the lower belly wall fails to close in time.
Bladder wall closure problem – the front of the bladder does not form a closed tube.
Large, fragile “cloacal membrane” – a thin early membrane blocks normal tissue growth and then breaks. This is a common theory.
Poor movement of mesenchyme – support tissue does not move into the lower belly to make muscle and skin.
Abnormal splitting of the pubic bones – the pelvis stays wide and open in front.
Urethral plate stays open – the urethra does not roll into a tube (epispadias).
Abnormal position of developing organs – bladder and genital organs sit too far forward.
Gene effects – small changes in many genes may raise risk (no single gene explains most cases).
Family clustering – rarely, more than one person in a family is affected, showing some inherited risk.
Male sex risk – boys are affected more often than girls.
First-born risk – some series show more first-born babies are affected (not a strict rule).
Young maternal age – reported in some studies (not always).
Assisted reproduction link (weak) – some studies suggest a small association, but evidence is not strong.
Twinning – rare twin cases suggest early embryo events matter.
Certain medications (unproven) – no consistent drug cause has been proven.
Environmental factors (unclear) – no single toxin is confirmed; research continues.
Placental or umbilical problems (theory) – could change blood flow and growth signals; evidence is limited.
Abnormal early folding of the embryo – the body does not “fold” and close in front correctly.
Spinal/caudal development issues – sometimes linked with spine or anus defects in severe forms.
Random developmental error – in most cases, it seems to occur by chance during early growth. BioMed Central+2PMC+2

Symptoms and signs

In newborns and children

Open, red bladder plate on the lower belly that leaks urine all the time.
Wet lower belly and skin irritation because urine continuously touches the skin.
Wide gap between pubic bones (pelvic bones) seen on exam or X-ray.
Separated belly muscles in the midline (a visible gap).
Open urethra (epispadias) – in boys, the opening is on top of the penis; in girls, the urethral opening sits higher and the clitoris may be split.
Short or curved penis in boys; abnormal labia and small vagina in girls.
Poor bladder control – bladder cannot store urine; later, continence is a major goal of surgery.
Urinary tract infections due to open tissues and short path for germs.
Reflux of urine to kidneys (vesicoureteral reflux) in many cases.
Kidney swelling (hydronephrosis) from reflux or blockage.
Hernias in the groin (inguinal hernia) due to weak wall.
Bowel symptoms in severe forms (constipation, exposed bowel in cloacal exstrophy).
Gait differences – legs may turn outward due to the wide pelvis.
Psychosocial stress – body image, continence, and many surgeries can affect mood and confidence.
Fertility and sexual function concerns in adulthood – these depend on anatomy and past surgeries; specialized care helps many patients. NCBI+1

Diagnostic tests

Doctors diagnose classic bladder exstrophy by looking at the baby. Testing then checks kidney safety, plans surgery, and watches growth. We will group tests as you asked.

A) Physical exam

Newborn full-body exam – the doctor sees the open bladder and checks skin, belly, genitals, and anus.
Pelvic width check – measures the gap between pubic bones; helps plan bone or soft-tissue steps in repair.
Genital exam – looks for epispadias, split clitoris, vaginal size, penile length and curvature.
Hernia check – looks for groin lumps that get bigger when the baby cries.
Spine and limb exam – checks for foot position, hip range, and any spinal findings in severe forms. NCBI

B) Manual / bedside tests

Skin protection assessment – nurses and doctors test skin barriers and dressings to protect the open area before surgery.
Continence diary (later childhood) – families record leaking, voiding times, and pad use to guide therapy.
Catheter trial after surgery – simple bedside test to see if the bladder empties well through a small tube.
Pelvic floor squeeze check (older children/teens) – clinician checks if pelvic muscles can contract on command.
Abdominal pressure test – gentle cough or strain to see if urine loss happens with pressure.

C) Lab and pathological tests

Urinalysis – looks for infection, blood, and protein.
Urine culture – grows bacteria to choose the right antibiotic if infection is present.
Blood kidney tests (creatinine, BUN, electrolytes) – confirm kidney function is safe.
Urine electrolytes and osmolality (selected cases) – helps understand kidney handling of salts and water.
Pathology review (after surgery) – if any tissue is removed, the lab confirms what it is and checks for inflammation or other changes. NCBI

D) Electrodiagnostic / functional urology tests

Urodynamics (pressure-flow study) – tiny catheters measure bladder pressure, capacity, and control; shows if urine reflux or leak occurs during filling.
Electromyography (EMG) of pelvic floor – checks signals from pelvic muscles during filling and voiding.
Uroflowmetry (for toilet-trained children) – patient voids into a machine; the flow curve helps judge bladder outlet function after repairs. NCBI

E) Imaging tests

Renal and bladder ultrasound – painless sound-wave pictures of kidneys and bladder; looks for swelling, stones, and bladder wall thickness.
Voiding cystourethrogram (VCUG) – dye goes into the bladder via a catheter; X-rays show reflux to the kidneys and the urethral channel after repairs.
Pelvic X-ray – shows how far the pubic bones are apart; helps surgical planning.
MRI of pelvis – gives a 3-D view of soft tissue and pelvic floor; useful for complex planning.
CT scan (rarely used in children) – detailed bone and organ view if needed; used sparingly to avoid radiation.
Prenatal ultrasound – during pregnancy, signs such as a small or absent bladder and wide pubic bones can suggest exstrophy.
3-D ultrasound or fetal MRI – in selected cases, these better map the baby’s anatomy before birth. Mayo Clinic+1

Non-pharmacological treatments (therapies & others)

Newborn bladder and abdominal wall protection (pre-op care).
What it is: Right after birth, the exposed bladder plate is covered with sterile, moist dressings; the baby is kept warm, hydrated, and protected from infection while transfer to a specialty center is arranged. Purpose: Prevent drying, infection, and injury until surgery. Mechanism: Gentle moisture barriers and infection control reduce contamination of the bladder mucosa; careful positioning prevents pressure and trauma. Early specialty transfer enables timely closure and best outcomes. Mayo Clinic
Modern staged repair pathway coordination.
What it is: A planned series—initial bladder and abdominal wall closure (often with pelvic osteotomy), epispadias repair, then bladder neck reconstruction when the bladder is bigger. Purpose: Build bladder capacity and continence step by step while protecting kidneys. Mechanism: Staging lets tissues heal and grow between operations, improving continence and upper-tract safety over time. SpringerOpen+1
Complete primary repair (select centers).
What it is: Some centers perform a “single-setting” closure that combines bladder, abdominal wall, and epispadias repair. Purpose: Reduce total surgeries for selected patients and potentially improve alignment early. Mechanism: En-bloc reconstruction aims to recreate bladder and outlet anatomy in one operation when feasible. Translational Andrology and Urology+1
Pelvic osteotomy and immobilization techniques.
What it is: Controlled cuts in the pelvic bones (various patterns: bilateral iliac, Y-osteotomy, “bayonet” techniques) plus immobilization methods to bring the pubic bones together. Purpose: Reduce pubic diastasis, support soft-tissue closure, and improve continence potential. Mechanism: Aligning the pelvis reduces tension on the bladder/abdominal repair and provides mechanical support for the urethra and pelvic floor. BioMed Central+3ScienceDirect+3PubMed+3
Clean intermittent catheterization (CIC) training.
What it is: Teaching families/older children to periodically pass a clean catheter to empty the bladder if needed after reconstruction or augmentation. Purpose: Keep bladder pressures low and prevent urine retention and infections. Mechanism: Regular, complete emptying limits high-pressure storage and reduces stasis that fosters infection. MDPI
Pelvic floor therapy and biofeedback (when age-appropriate).
What it is: Guided exercises, sometimes with biofeedback, to strengthen and coordinate pelvic muscles. Purpose: Support continence goals and reduce leakage where anatomy allows functional gains. Mechanism: Neuromuscular training improves sphincter coordination and reduces detrusor–sphincter dyssynergia in selected patients. SpringerOpen
UTI-prevention lifestyle bundle.
What it is: Adequate fluids, timed voiding/CIC schedule, gentle perineal hygiene, constipation prevention, and careful diaper/skin care. Purpose: Lower recurrent UTI risk and protect kidneys. Mechanism: Diluting urine, preventing stool burden, and reducing perineal bacterial load all reduce ascending infection risk and bladder pressures. Uroweb+1
Kidney protection monitoring.
What it is: Regular ultrasound, renal function labs, and urodynamics after reconstruction. Purpose: Detect reflux, obstruction, or high-pressure storage early. Mechanism: Surveillance identifies problems before damage occurs so the care plan can be adjusted. MDPI

What it is: Teaching dressing changes, ostomy/continent stoma care (Mitrofanoff), and skin protection. Purpose: Prevent infections and skin breakdown. Mechanism: Good local care keeps tissues healthy and lowers bacterial contamination. MDPI
Hydration coaching.
What it is: Simple, age-appropriate fluid targets and spacing through the day. Purpose: Dilute urine, discourage crystals, and aid emptying. Mechanism: Adequate free water reduces irritants and helps prevent UTIs. Uroweb
Antibiotic-stewardship education.
What it is: Using cultures, avoiding treatment of asymptomatic bacteriuria, and limiting unnecessary antibiotics. Purpose: Protect the microbiome and reduce resistance. Mechanism: Evidence-based rules reduce avoidable antibiotic exposure while still treating real infections promptly. Uroweb
School/day-care continence plans.
What it is: Written plans for bathroom/CIC breaks, supplies, and privacy. Purpose: Prevent accidents and UTIs; reduce stigma. Mechanism: Predictable schedules maintain low bladder pressures and complete emptying. Mayo Clinic
Sexual and reproductive counseling (teens/young adults).
What it is: Sensitive counseling on sexual function, fertility, pregnancy, and delivery planning in women and men with prior repairs. Purpose: Prepare families and patients for adult health decisions. Mechanism: Early education reduces anxiety and supports informed choices. BioMed Central
Prenatal counseling and delivery planning (future pregnancies).
What it is: For families with history, discuss prenatal ultrasound signs, referral, and delivery at an experienced center. Purpose: Improve early care for affected newborns. Mechanism: Coordinated prenatal–neonatal handoffs speed protective care and closure timing. auanews.net+1
Bowel program to prevent constipation.
What it is: Fiber, fluids, routine toileting; sometimes stool softeners (per clinician). Purpose: Reduce bladder pressure and UTIs. Mechanism: Less straining and stool load decreases pelvic floor dysfunction and bacterial spread. Uroweb
Nutrition for healing.
What it is: Age-appropriate calories, protein, and micronutrients during peri-operative periods. Purpose: Support wound healing and growth. Mechanism: Adequate protein and vitamins enable tissue repair after major reconstruction. MDPI
Infection-control training at home.
What it is: Hand hygiene, catheter handling, and dressing changes. Purpose: Lower post-op and CIC-related infections. Mechanism: Interrupts contamination pathways. Uroweb
Shared-care roadmap.
What it is: Clear schedule for imaging, urodynamics, clinic visits, and who to call for fever or poor output. Purpose: Prevent silent kidney damage and manage issues early. Mechanism: Standardized follow-up catches problems sooner. MDPI

Immunity-booster / regenerative / stem-cell” drugs

Reality check: There are no FDA-approved “immunity boosters,” regenerative, or stem-cell drugs for treating bladder exstrophy. Tissue-engineered bladders have been studied in other conditions, but these approaches are not routine care for exstrophy, and the FDA warns strongly against unapproved stem-cell products marketed directly to patients. Below are six explanatory notes to guide safe decisions:

Unapproved stem-cell products—avoid outside trials. FDA warns of serious harms (infections, blindness, tumors) from unapproved stem-cell offerings. Dose/Mechanism: Not applicable; do not use outside regulated trials. U.S. Food and Drug Administration+1
Regenerative medicine consumer alerts. FDA and independent reviews document ongoing injuries from direct-to-consumer clinics; enforcement continues. Dose/Mechanism: Not applicable; seek only IRB-approved trials. ashpublications.org+1
Historic tissue-engineered bladder research. Early clinical reports in myelomeningocele showed feasibility but remain limited; this is not standard exstrophy care. Dose/Mechanism: Cell-seeded scaffolds; investigational. PubMed+1
Media/advocacy pieces are not medical approval. News about stem-cell “crackdowns” or permissive state laws does not equal safety or FDA approval. Action: Rely on FDA and your surgeon. time.com+1
If offered a “regenerative” add-on, ask for the FDA IND/IDE number. Legitimate studies list FDA oversight and ethics board approval. Action: Verify on ClinicalTrials.gov. U.S. Food and Drug Administration
Focus on proven pathways. Kidney protection, staged reconstruction, bladder management, and infection prevention have the strongest evidence today. Action: Partner with experienced exstrophy teams. SpringerOpen+1

Surgeries

Initial bladder and abdominal wall closure (often with pelvic osteotomy).
Procedure: Return bladder into the pelvis, close the bladder and belly wall; osteotomy brings pubic bones together. Why: Protect bladder mucosa, enable growth/capacity, and create the base for continence and further repairs. ScienceDirect+1
Epispadias repair.
Procedure: Reconstruct urethra and external genitalia (timing varies). Why: Improve urine channel alignment, continence mechanics, and genital appearance/function. SpringerOpen
Bladder neck reconstruction (continence surgery).
Procedure: Tighten and lengthen the bladder outlet when bladder capacity allows. Why: Achieve social continence while protecting upper tracts. SpringerOpen
Augmentation cystoplasty (selected cases).
Procedure: Enlarge bladder (often with intestinal segment) or consider tissue-engineering only in trials. Why: Lower storage pressure and improve continence when native bladder remains small/high-pressure. MDPI+1
Continent catheterizable channel (Mitrofanoff).
Procedure: Create a small stoma to pass a catheter easily through the belly. Why: Enable painless, independent bladder emptying when urethral catheterization is hard. MDPI

Frequently asked questions

Is exstrophy curable with one surgery?
Not usually. Most children need staged surgeries and years of follow-up to build capacity, improve continence, and protect kidneys. SpringerOpen
Why do some babies need pelvic osteotomy?
Bringing the pubic bones together reduces tension on the repair, helps close the bladder and belly wall, and supports better long-term continence. ScienceDirect
Can children become continent?
Many achieve social continence with staged reconstruction, bladder growth, and sometimes bladder neck surgery; others use CIC and/or continence channels. SpringerOpen
Will the kidneys be safe?
With low-pressure storage, complete emptying, and rapid UTI treatment, kidneys are usually protected—regular imaging and urodynamics check this. MDPI
Are anticholinergic medicines safe for kids?
They are widely used but require specialist oversight for dose, side effects (constipation, dry mouth), and monitoring; alternatives like mirabegron exist for selected cases. FDA Access Data+1
Do cranberry pills prevent UTIs?
Cranberry may help reduce recurrent UTIs in some groups, but results vary; discuss with your clinician. It does not treat active infections. jamanetwork.com
Does D-mannose work?
Recent high-quality evidence shows little or no benefit for preventing recurrent UTIs; don’t rely on it as your only strategy. jamanetwork.com
Is methenamine hippurate an antibiotic?
It’s a urinary antiseptic that releases formaldehyde in acidic urine and can reduce recurrences in some patients; avoid urine-alkalinizing agents and certain drug combinations. FDA Access Data
Should asymptomatic bacteriuria be treated?
Generally no, because treatment can be harmful; decisions depend on symptoms, cultures, and your urology plan. Uroweb
Are stem-cell or “regenerative” injections a cure?
No approved stem-cell therapies exist for bladder exstrophy; the FDA warns against unapproved products sold to patients. Consider only regulated clinical trials. U.S. Food and Drug Administration
Can girls with exstrophy have babies?
Many can, but pregnancy requires high-risk obstetric and urology planning; modes of delivery vary by reconstruction type. BioMed Central
What if closure fails?
Re-closure and additional procedures are possible; pelvic osteotomy and immobilization techniques improve success rates. auajournals.org+1
Why is constipation such a big issue?
Constipation raises pelvic pressure and worsens leakage and UTIs; a daily bowel program protects the bladder and kidneys. Uroweb
Do we always need antibiotics after surgery?
Hospitals use short, targeted prophylaxis; long courses without indication are avoided to reduce resistance. Uroweb
What specialists are on the team?
Pediatric urology, anesthesia, radiology, nephrology, orthopedic surgery (for osteotomy), nursing/wound/ostomy care, physical therapy, nutrition, and psychosocial support. SpringerOpen
