Bladder exstrophy–epispadias–cloacal exstrophy complex (BEEC) is a group (a spectrum) of rare birth defects that affect the front wall of the belly and the lower urinary and genital organs. In BEEC, parts that should be inside the body form on the outside or open to the outside. In epispadias, the urine tube opening is on the top side (not at the tip) and the pelvic bones in front may be wide apart. In classic bladder exstrophy, the bladder is split open and lies on the outside of the abdominal wall, and the pubic bones are separated. In cloacal exstrophy, the most severe form, the bladder and bowel are split and open on the outside, often with a belly-wall herniation (omphalocele), an imperforate anus, and spinal defects. Because these problems form very early in pregnancy, babies are typically diagnosed at birth or on prenatal imaging. All forms require coordinated surgical care and long-term follow-up to support urinary continence, kidney protection, bowel function, sexual health, and quality of life. NCBI+2PMC+2
BEEC is a group of rare birth differences in which the lower belly wall and urinary system do not form normally before birth. In epispadias, the urine tube (urethra) opens on the top side instead of the tip (boys) or the opening is split/too wide (girls). In classic bladder exstrophy, the bladder sits open on the outside of the belly at birth, the pubic bones are widely separated, and the pelvic floor muscles are weak. In cloacal exstrophy, the most severe form, the bladder is split and open, the intestines can also be outside, and babies often have other differences such as imperforate anus and spine or limb changes. The main goals of care are: close the bladder and belly wall, protect the kidneys, help the child become as dry/continent as possible, and support healthy sexual, bowel, and social function over life. Modern care uses modern staged repair of exstrophy (MSRE) or complete primary repair of exstrophy (CPRE) plus pelvic osteotomies to help the bones meet so closure holds. PMC+3SpringerOpen+3PMC+3

Types
1) Epispadias (mildest end of the spectrum).
The urinary opening is on the top of the penis in boys or splits the clitoris in girls. The pubic bones are often separated (pubic diastasis). Urinary leakage can occur if the bladder outlet does not close well. Epispadias can exist alone or with other exstrophy features. NCBI
2) Classic bladder exstrophy (middle of the spectrum).
The bladder is split open and exposed on the lower abdomen. The belly wall is open below the umbilicus. The urethra and external genitals are split, and the front pelvic bones do not meet in the center. Urine constantly leaks from the open bladder plate. Early, careful surgery aims to close the bladder and the belly wall, bring the pelvic bones closer together, and later improve continence. NCBI+1
3) Cloacal exstrophy (most severe end of the spectrum).
The bladder and the lower bowel are split and open on the abdomen, often with an omphalocele (a sac at the umbilicus), an imperforate anus, and spinal defects. Babies often need staged, lifesaving operations soon after birth and long-term bowel and urinary management. PMC+1
Causes
Important note: For most families, no single cause is found. BEEC results from an early embryologic problem of the front body wall and lower urinary/bowel tract. The items below describe risk mechanisms or associations that research and expert reviews discuss. NCBI+1
Abnormal early belly-wall development.
When the lower abdominal wall does not form or close correctly very early in pregnancy, internal organs can remain outside. This is the core mechanism in exstrophy. NCBILarge or fragile early cloacal membrane.
A larger-than-normal early membrane may block tissue from moving inward; if it ruptures, organs can open onto the belly surface. This classic embryologic theory helps explain the spectrum of severity. ResearchGateFailure of mesenchymal (soft tissue) migration.
Tissues that should move in to form muscle and fascia in the lower belly do not reach the midline, leaving a gap. NCBIPubic bone separation (pubic diastasis) as a developmental effect.
The front pelvic bones do not close, which is part of the same developmental error and contributes to urinary leakage and gait issues. NCBIGenetic susceptibility (polygenic).
Most cases are sporadic, but the condition can recur in families at a low rate, suggesting shared susceptibility rather than a single gene for most patients. AU A JournalsRare chromosomal changes.
Some babies have copy-number variants or chromosomal differences on genetic testing; these are uncommon and not the rule but can contribute in certain cases. NCBIMale sex (epispadias more common in boys).
Sex-related developmental pathways may influence risk; epispadias is observed more often in males. NCBIMaternal factors (general).
Most mothers did nothing to cause BEEC. Some studies explore links with general pregnancy factors, but no consistent, strong, preventable factor has been proven. FrontiersEnvironmental influences (hypothesized).
Researchers have studied possible environmental exposures; evidence is mixed and not definitive, but environment may interact with genes in some families. FrontiersAbnormal rotation or separation of the cloaca.
Early failure of normal division of the cloaca (common chamber for bowel and urinary tracts in the embryo) can lead to severe forms like cloacal exstrophy. PMCSpinal development anomalies linked to cloacal exstrophy.
Spinal dysraphism (like myelomeningocele or hemivertebrae) often co-occurs in OEIS, reflecting a broad midline developmental field problem. GARD Information CenterOmphalocele as part of the same field defect.
An umbilical herniation of organs (omphalocele) commonly appears with cloacal exstrophy, pointing to a shared early defect. GARD Information CenterImperforate anus due to failed anorectal development.
The anal opening does not form or is blocked; in cloacal exstrophy this is common and part of OEIS. GARD Information CenterPelvic floor muscle maldevelopment.
Weak or mispositioned pelvic muscles reduce bladder outlet resistance and continence potential. PMCAbnormal genital tubercle development (epispadias).
Incorrect position and rotation of the genital tubercle alters the urethral opening location. NCBIAssociated kidney/ureter anomalies.
Reflux, duplicated systems, or dysplasia can co-occur, reflecting broader urogenital development issues. PMCHernias due to weak inguinal tissues.
Groin hernias are frequent because the anterior abdominal wall and inguinal canal develop abnormally. PMCHip and gait changes from a wide pelvis.
A broad pelvic ring alters biomechanics and can cause waddling; this is secondary to the bony defect. PMCPsychosocial stressors as downstream effects.
Repeated surgeries and continence challenges can affect mental health; these are not causes of BEEC but are part of the overall burden. tau.amegroups.orgUnknown/idiopathic in most cases.
Despite research, most families never get a precise “cause.” The best approach focuses on coordinated care and long-term support. NCBI
Symptoms and signs
Visible open bladder plate (classic exstrophy).
At birth the bladder mucosa is exposed on the lower abdomen and urine drips continuously. NCBISeparated pubic bones and a wide, flat lower belly.
The front of the pelvis is open; the umbilicus sits high; the belly wall is low and split. NCBIEpispadias with urine leakage.
The urethral opening lies on the top of the penis or splits the clitoris; leakage and spraying are common. NCBIAbnormal external genitalia.
Boys may have a short, upward-curved penis; girls may have separated labia and a split clitoris. PMCConstant wetness (incontinence) before repair.
Because the bladder is open or the outlet is weak, urine cannot be stored. PMCRecurrent urinary infections.
Exposed mucosa and abnormal urine flow raise infection risk; careful hygiene and follow-up are important. PMCGroin hernias.
Soft tissue weakness and open inguinal canals increase hernia risk. PMCWide-based gait or waddling when walking.
The pelvis is wide and the hips may rotate differently; some children have a characteristic gait. PMCKidney/ureter problems (reflux, hydronephrosis).
Backflow of urine can injure kidneys if not detected and treated. PMCSkin irritation on the lower abdomen.
Urine exposure can cause redness and infection around the bladder plate before closure. PMCIn cloacal exstrophy: open bowel and omphalocele.
There may be two hemibladders with bowel mucosa between, plus an umbilical hernia sac and no anal opening. PMC+1Spinal findings in cloacal exstrophy.
Back dimples, masses, or limb differences can reflect spinal dysraphism. GARD Information CenterBowel control issues (especially in cloacal exstrophy).
Many children need bowel programs or stomas to manage stooling. PMCFertility and sexual function concerns later in life.
With modern care, many patients achieve relationships and parenthood, but some need tailored counseling and support. tau.amegroups.orgPsychosocial impact from repeated surgeries and continence work.

Diagnostic tests
A) Physical examination (what clinicians see and feel)
Newborn surface exam.
Clinicians see an open bladder plate (classic exstrophy) or open bladder and bowel plates (cloacal exstrophy). The umbilicus is high and the lower abdominal wall is split. This confirms the diagnosis at birth in most cases. NCBIGenital examination.
In epispadias, the urethral opening location is abnormal; in exstrophy the urethra and external genitalia are split. This guides future reconstructive planning. NCBIPelvic width and pubic diastasis assessment.
A wide gap between pubic bones is palpable and visible; this affects continence potential and surgical strategy. PMCAnal opening check.
In cloacal exstrophy, the anus may be absent (imperforate); the perineum is carefully inspected to plan urgent bowel care. GARD Information CenterHernia examination.
Inguinal hernias are common; the examiner looks for groin bulges and reducibility to plan repair timing. PMC
B) Manual tests (bedside maneuvers and simple probes)
Gentle bladder-plate palpation and observation.
Careful palpation and watching urine flow help estimate bladder tissue quality and outlet function before surgery. (Done gently to avoid mucosal trauma.) PMCPelvic ring compression test.
Manual inward pressure over the iliac wings estimates pelvic mobility and the likely need for osteotomy at closure. PMCDigital rectal examination (when appropriate).
Assesses anal tone (if present), perineal reflexes, and pelvic floor muscle activity to plan continence support. PMCMeatal/urethral probing in epispadias (delicate).
A small soft catheter may be passed to gauge urethral patency and course—this guides urethral reconstruction. (This is done by specialists.) NCBIHernia reduction and cough impulse.
Bedside tests confirm inguinal hernias and help prioritize repair. PMC
C) Laboratory and pathological tests
Basic blood tests (electrolytes, kidney function).
Serum creatinine and electrolytes show how well the kidneys are working and whether dehydration or acidosis is present—crucial before anesthesia and after surgery. PMCUrinalysis and culture (when obtainable).
Collecting urine is different before closure, but once a stoma or catheter is present, testing helps detect infection and guides antibiotics. PMCUrine protein testing (after reconstruction).
Protein in the urine can signal kidney strain, prompting closer imaging and reflux management. PMCGenetic testing (karyotype or microarray when indicated).
While most cases are not due to a single gene, testing may find chromosomal differences in selected patients, especially with multiple anomalies. NCBIPrenatal screening labs.
Very high maternal alpha-fetoprotein can occur with major abdominal wall defects like omphalocele, often present in cloacal exstrophy, prompting detailed imaging. PMC
D) Electrodiagnostic and functional tests
Urodynamic studies (after initial repairs).
Cystometry, uroflowmetry, and leak-point pressure testing measure bladder capacity, compliance, and outlet resistance. Pelvic-floor EMG during urodynamics shows coordination, guiding continence strategies. PMCPelvic floor electromyography (EMG).
Surface or needle EMG helps assess sphincter activity and timing, useful when continence is difficult after reconstruction. PMCVideo urodynamics.
Combines pressure testing with imaging to visualize reflux and outlet function during filling and voiding, helping decide on bladder-neck or augmentation surgery. PMC
E) Imaging tests
Prenatal ultrasound.
Second-trimester scans may show a persistently absent fetal bladder, low abdominal wall defects, omphalocele, and spinal anomalies, suggesting exstrophy or OEIS before birth. PMCPostnatal renal and bladder ultrasound.
Ultrasound checks kidneys (hydronephrosis, size) and bladder remnants, and monitors after each operation to protect renal function. PMCPelvic and hip X-rays.
Radiographs measure the pubic gap and pelvic angles, informing whether pelvic osteotomies are needed during closure. PMCVoiding cystourethrogram (VCUG) after reconstruction.
VCUG looks for vesicoureteral reflux and checks the bladder neck and urethra after repairs; results guide reflux treatment and continence planning. PMCSpine ultrasound or MRI (especially in OEIS).
These studies look for tethered cord or other spinal defects that may need neurosurgical attention. GARD Information CenterFetal MRI (when available).
Provides more detail about abdominal wall, bowel, and spine in suspected cloacal exstrophy, helping plan delivery and immediate care. PMCPelvic MRI in older children.
Shows pelvic floor muscles, continence mechanisms, and genital anatomy before complex reconstructions. PMCContrast enema (in cloacal exstrophy).
Outlines colon length and position and helps plan staged bowel reconstruction or stoma creation. PMCEchocardiogram (selectively).
Major abdominal wall defects sometimes co-occur with heart anomalies; screening is individualized by the care team. PMC3-D CT for pelvic planning (rarely in children).
When needed, 3-D imaging may help orthopedic teams plan pelvic osteotomies, used sparingly to limit radiation. PMCBone density or alignment follow-up (later).
Selected children get imaging to monitor gait and hip development after pelvic repairs. PMCFollow-up ultrasounds and VCUGs over time.
Because children grow, repeating imaging helps safeguard kidneys and adjust continence plans. PMC
Non-pharmacological treatments (therapies & other supports)
Modern Staged Repair of Exstrophy (MSRE) education & planning
Purpose: Help families understand the three steps (initial bladder/abdominal closure; epispadias repair; continence surgery later) and prepare for timing, hospital stay, and follow-ups. Mechanism: Breaking care into stages lowers body stress, lets the bladder grow, and gives the team time to tailor continence surgery based on how the bladder and sphincter develop. SpringerOpenComplete Primary Repair of Exstrophy (CPRE) pathway counseling
Purpose: Explain the “all-in-one” early repair (bladder closure + epispadias repair) used at experienced centers and set expectations for possible later procedures. Mechanism: A unified operation aligns the bladder and urethra at once; benefits depend on surgeon experience and strict peri-operative protocols. auau.auanet.org+1Pelvic osteotomy & external fixation education
Purpose: Prepare parents for bone cuts and temporary fixators that allow pubic bones to come together so the belly wall and bladder can close with less tension. Mechanism: Easier bony closure reduces pull on soft tissues, lowering dehiscence and wound issues and improving bladder closure success. Riley Children’s Health+1Clean Intermittent Catheterization (CIC) training (urethral or Mitrofanoff)
Purpose: Teach safe, regular emptying when needed after reconstruction or augmentation. Mechanism: CIC prevents overfilling, lowers pressure on kidneys, and reduces infection risk when done with clean technique and proper supplies. Agency for Clinical Innovation+1Mitrofanoff (continent catheterizable channel) self-care program
Purpose: For children/teens who struggle with urethral catheterization, a small stoma on the belly allows easy, private CIC. Mechanism: A tunneled valve from appendix/ileum into a low-pressure bladder/reservoir resists leakage but opens to a small catheter, improving independence and continence. PMC+1Skin & stoma care bundle
Purpose: Protect the belly skin around dressings/stomas, prevent rashes and infections, and support wound healing after closure or diversions. Mechanism: Barrier creams, gentle cleansing, correct wafer fit, and moisture control reduce maceration and bacterial growth at the skin-urine interface. Boston Children’s HospitalPelvic floor physiotherapy (when appropriate after repair)
Purpose: Strengthen available pelvic muscles and improve squeeze/coordination for continence support in selected patients. Mechanism: Targeted exercises and biofeedback help recruit muscles that assist the reconstructed bladder neck and urethra. SpringerOpenUTI prevention education (hydration, timed voiding/CIC, hygiene)
Purpose: Lower infection risk without routine antibiotics. Mechanism: Regular emptying keeps bladder pressures low and reduces bacterial dwell time; hydration dilutes urine; front-to-back hygiene reduces contamination. Agency for Clinical InnovationPain & spasm non-drug measures
Purpose: Ease discomfort from traction/fixators and bladder spasms. Mechanism: Positioning, splinting with pillows, warm packs (when allowed), and distraction techniques reduce perceived pain and muscle tension alongside medical care. ScienceDirectBowel program & constipation prevention
Purpose: Prevent hard stools that increase pelvic pressure and leakage. Mechanism: Fiber, fluids, toilet routine, and stool-softening strategies reduce strain that can stress repairs and continence. Boston Children’s HospitalNutrition optimization for healing

Purpose: Discuss anatomy after epispadias/cloacal repairs, function, fertility, and safe intimacy. Mechanism: Education plus referral to specialists reduces fear, supports healthy relationships, and aids informed decisions. PMCKidney protection monitoring (ultrasound & labs)
Purpose: Catch back-pressure or scarring early. Mechanism: Scheduled imaging and kidney function tests detect reflux, obstruction, or high pressures so care can be adjusted promptly. ScienceDirectBladder diary & leak log
Purpose: Track continence, CIC intervals, and triggers. Mechanism: Data-driven tweaks to timing, fluids, and meds improve dryness safely. Boston Children’s HospitalPeri-operative traction/external fixation protocols
Purpose: Stabilize closure and reduce tension. Mechanism: Standardized positioning and traction reduce wound stress and improve success after primary closure. ScienceDirectOrthopedic follow-up for gait/pubic diastasis
Purpose: Monitor hip/pelvic alignment and walking mechanics over time. Mechanism: Early therapy or bracing can address gait strain after diastasis repair. Riley Children’s HealthAdolescent transition clinic
Purpose: Shift to adult urology/gynecology care smoothly. Mechanism: Structured transfer keeps surveillance (kidneys, continence, sexual health) on track into adulthood. PMCCranberry strategy (adjunct for rUTI—discuss with team)
Purpose: Reduce symptomatic UTIs in select patients who catheterize. Mechanism: A-type proanthocyanidins limit bacterial sticking to bladder lining; evidence is moderate for prevention (not treatment). Cochrane Library+1Probiotic strategy (adjunct, case-by-case)
Purpose: Support a protective urogenital micro-environment in those with frequent UTIs. Mechanism: Lactobacillus species can compete with pathogens and reduce adhesion; evidence suggests possible benefit but remains mixed and evolving. PMC+1
Drug treatments
Oxybutynin (Ditropan/XL) – Antimuscarinic for bladder spasms/overactivity
Dose & time: Adults commonly 5–10 mg XL once daily (titrate per response). Pediatric dosing exists on some oxybutynin formulations; specialist guidance needed. Purpose: Lower involuntary bladder squeezes after reconstruction/augmentation to improve dryness. Mechanism: Blocks M-muscarinic receptors in detrusor muscle, reducing contractions and raising capacity. Side effects: Dry mouth, constipation, blurred vision; rare angioedema—seek urgent care. Note: Contraindications include urinary retention and uncontrolled narrow-angle glaucoma. FDA Access Data+1Tolterodine (Detrol/Detrol LA) – Antimuscarinic
Dose: Detrol LA 4 mg once daily (2 mg if renal/hepatic impairment or strong CYP3A4 inhibitors). Purpose/Mechanism: Similar to oxybutynin, with bladder-calming effect via muscarinic blockade.

Purpose/Mechanism: Create moisture barrier to protect healing skin from urine and adhesives, lowering rash and breakdown. Boston Children’s Hospital
Important honesty note: There are no FDA-approved medicines that “cure” BEEC itself; drugs are used to protect kidneys, help continence, manage pain/spasm, and treat or prevent infection—always under a specialist. PMC
Dietary molecular supplements
Cranberry PACs – 150–500 mg PACs/day in tested formulations may lower recurrent UTI risk by limiting bacterial adhesion; not a treatment for active infection and not effective in every group. Cochrane Library+1
Probiotic Lactobacillus (e.g., L. rhamnosus GR-1/L. reuteri) – Doses vary by product; may help restore a protective urogenital flora and reduce rUTIs; evidence suggests benefit but is mixed. PMC
Vitamin C (ascorbic acid) – 250–500 mg 1–2×/day; sometimes used to acidify urine (limited evidence); can support wound healing post-op. Avoid excess doses that cause stones/diarrhea. Boston Children’s Hospital
Zinc – 10–20 mg/day short-term aids wound repair by supporting collagen and immune enzymes; avoid chronic high doses (copper deficiency risk). Boston Children’s Hospital
Protein supplementation (whey or oral nutrition shakes) – Dosage per dietitian; supports tissue repair after major surgery. Boston Children’s Hospital
Fiber (psyllium/inulin) – 5–10 g/day to prevent constipation that worsens leakage and pressures on repairs. Boston Children’s Hospital

Immunity booster / regenerative / stem-cell drugs
Reality check: There are no FDA-approved stem-cell or “regenerative” drugs to repair the bladder or pelvic floor in BEEC, and no approved “immunity boosters” specific to BEEC. Tissue-engineered bladder grafts remain investigational and are not standard of care. Best “immune protection” is routine vaccination, nutrition, sleep, and infection prevention. Here are six safe, practical medical actions your team may use instead:
Routine vaccines (per age schedule) – Keeps infections that could stress kidneys/repairs at bay; follow national schedules. Boston Children’s Hospital
Influenza/COVID boosters as indicated – Lower febrile illness burden that can worsen dehydration and UTI risk. Boston Children’s Hospital
Nutritional repletion (protein, vitamin C, zinc) – Supports wound and bone healing; see diet section. Boston Children’s Hospital
Anemia correction (iron/B12/folate as needed) – Optimizes tissue oxygenation post-op. Boston Children’s Hospital
Physical therapy (graded) – Enhances function and reduces complications without drugs. SpringerOpen
Clinical trial referral (if available) – Access to investigational regenerative methods under ethics oversight—not standard care. PMC
Surgeries
Primary bladder and abdominal wall closure
What: Close the bladder and rebuild the belly wall soon after birth (MSRE or CPRE). Why: Protects bladder tissue, allows growth, reduces infection risk, and sets the stage for continence. Pelvic osteotomy often supports closure. SpringerOpen+1Epispadias repair
What: Reconstruct the urethra/penis or urethra/vulva to align the urine tube and improve function/appearance. Why: A straighter, more functional urethra helps continence and sexual function later. auau.auanet.orgPelvic osteotomy (sometimes staged) with fixation
What: Cut and reposition pelvic bones so pubic bones meet; add temporary external fixation. Why: Reduces tension on closures, improves hold, and lowers wound failure. PubMed+1Continence surgery (e.g., bladder neck reconstruction; augmentation cystoplasty in select cases)
What: Tighten bladder outlet and/or enlarge bladder with bowel patch if capacity/pressure remain poor. Why: Achieve dryness and protect kidneys when conservative steps are not enough. PMCMitrofanoff (continent catheterizable channel) ± Malone (bowel flush channel)
What: Create a small stoma to pass a catheter into the bladder (and, if needed, a channel to flush the colon). Why: Enables easy, private emptying and better dryness; improves independence and QOL. PMC

FAQs
1) Is BEEC caused by something parents did?
No. The exact cause is unknown; it happens during early fetal development. Family recurrence risk is low, but genetics may play a small role. Children’s Hospital of Orange County
2) Which is better—MSRE or CPRE?
Both are used at expert centers. Choice depends on the child’s anatomy and the team’s expertise. Long-term continence often needs additional surgery. SpringerOpen+1
3) Why are pelvic osteotomies common now?
They let the pubic bones meet so the soft-tissue closure is under less tension, improving closure success and lowering wound complications. Riley Children’s Health
4) Will my child be dry/continent?
Many children reach social dryness with staged care, bladder therapies, and sometimes Mitrofanoff/CIC. Kidney protection is the top priority. PMC
5) Is catheterizing forever?
Some will need long-term CIC (urethra or Mitrofanoff). Others void by urethra after reconstructions. The plan is individualized. PMC
6) Are anticholinergics safe for kids?
Oxybutynin has pediatric use on certain labels; others have limited pediatric indications. Your pediatric urologist picks the safest option and dose. FDA Access Data
7) Is mirabegron used in children?
Yes, Myrbetriq granules have an FDA pediatric indication for neurogenic detrusor overactivity (not BEEC itself), with specialist dosing and BP monitoring. FDA Access Data
8) Do supplements cure BEEC?
No. At best, cranberry/probiotics may reduce recurrent UTIs in some people; D-mannose showed no benefit in a 2024 RCT. Cochrane Library+1
9) Can UTIs still happen after Mitrofanoff?
Yes, but CIC through a continent channel is often easier and may reduce infections for some compared with long-term tubes, with good adherence. PubMed
10) Are there stem-cell cures?
