Living with Exstrophy-epispadias complex

A group of birth differences of the lower belly wall, bladder, and genitals.

Understanding Exstrophy-epispadias complex

Exstrophy-epispadias complex (EEC) is a range of birth differences that include epispadias, bladder exstrophy, and cloacal exstrophy.

It causes a visible difference in the lower belly wall, and the abdominal muscles do not form normally. Depending on severity, it can affect the urinary system, bones, pelvis, belly wall, genitals, and sometimes the spine and anus. It is seen during pregnancy or at birth. GARD says there is no known cause.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Difference in the lower belly wall
  • Bladder exstrophy (bladder open on the outside of the belly)
  • Epispadias
  • Urine flowing back toward the kidneys (vesicoureteral reflux)
  • Bladder bulging out (cystocele)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists, kidney specialists and urinary and male reproductive system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Association for the Bladder Exstrophy Community may keep lists of experts for this condition.
