Which are the symptoms of Prune Belly Syndrome?

Prune Belly Syndrome, also known as Eagle-Barrett syndrome, is characterized by the triad of deficient abdominal wall musculature, urinary tract malformations, and undescended testes in males. Symptoms vary significantly in severity, ranging from life-threatening complications at birth to milder forms that allow for a relatively normal quality of life.

What are the primary symptoms of Prune Belly Syndrome?

The clinical presentation of Prune Belly Syndrome is defined by a distinct "prunelike" appearance of the abdominal wall due to absent or severely thin muscles. Beyond this, the condition involves complex urological issues. Common clinical features include:

• Abdominal wall deficiency: A wrinkled, lax appearance of the skin on the abdomen.


• Urinary tract abnormalities: Including megacystis (enlarged bladder), hydroureter (dilated ureters), and vesicoureteral reflux.


• Cryptorchidism: Both testicles fail to descend into the scrotum in male patients.


• Renal impairment: Varying degrees of kidney dysplasia or chronic kidney disease.

How does the severity of Prune Belly Syndrome vary?

The clinical spectrum of Prune Belly Syndrome is broad. Some infants are born with severe pulmonary hypoplasia (underdeveloped lungs) due to oligohydramnios, which can be fatal. Conversely, other individuals with Prune Belly Syndrome may have minimal renal involvement and only require surgical correction for cryptorchidism or abdominal wall reconstruction later in childhood.

Which symptoms impact daily quality of life?

For those living with Prune Belly Syndrome, the most significant long-term challenges involve managing chronic urinary tract infections and potential bladder dysfunction. Many individuals require intermittent catheterization or surgical interventions to manage urinary stasis. At DiseaseMaps.org, 64 community members have shared their experiences, highlighting that while physical limitations exist, many patients lead fulfilling lives with proactive, multidisciplinary care.

When should I seek immediate medical attention?

Families should seek urgent care if a patient with Prune Belly Syndrome experiences signs of acute kidney distress or infection. Key warning signs include high fever, decreased urine output, significant swelling (edema), or sudden abdominal pain, which may indicate an obstruction or severe urinary tract infection.
