Living with Prune belly syndrome

A condition present at birth with weak abdominal muscles, wrinkled belly skin, and urinary tract differences.

Understanding Prune belly syndrome

Prune belly syndrome is a condition present from birth with missing abdominal muscles, undescended testicles in males, and urinary tract differences.

The belly skin wrinkles and looks like a prune. It is more common in males. Severity varies a lot. Some people have significant kidney and lung problems, while others have few or no urinary problems. GARD says the cause is unknown.

Signs & symptoms

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

  • Missing or weak belly muscles
  • Wrinkled belly skin
  • Undescended testicles
  • Bladder and ureter differences
  • Frequent urinary tract infections
  • Kidney problems

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. Consider genetic testing

    Changes in CHRM3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
