How do I know if I have Prune Belly Syndrome?

Prune Belly Syndrome is a rare congenital condition characterized by the triad of partial or complete absence of abdominal wall muscles, urinary tract malformations, and undescended testicles (cryptorchidism) in males. It is typically diagnosed at birth or prenatally via ultrasound, though milder cases may be identified later in life through persistent urinary tract issues or physical examination.

What are the primary clinical signs of Prune Belly Syndrome?

In individuals with Prune Belly Syndrome, the most distinct feature is a wrinkled, "prune-like" appearance of the abdominal skin due to underdeveloped or absent abdominal muscles. Because the condition is congenital, it is almost always identified in infancy. If you are an adult questioning if you have Prune Belly Syndrome, look for a history of chronic urinary tract infections, recurrent kidney issues, or structural abnormalities of the bladder or ureters that were present from childhood.

How is Prune Belly Syndrome diagnosed?

Diagnosis is usually confirmed by a pediatric urologist or nephrologist using specific imaging and physical assessments. If you suspect you have undiagnosed Prune Belly Syndrome, you should request a consultation with a urologist to discuss the following diagnostic steps:

• Renal and bladder ultrasound: To visualize the anatomy of the urinary tract.


• Voiding cystourethrogram (VCUG): To assess bladder function and identify reflux.


• Physical examination: Specifically evaluating abdominal muscle tone and testicular position.


• Blood tests: To check kidney function markers like creatinine and BUN.

When should I seek urgent medical evaluation?

If you experience signs of kidney distress, such as significant flank pain, blood in the urine (hematuria), or sudden changes in urinary output, seek medical attention immediately. These can be red flags for complications related to Prune Belly Syndrome, such as severe hydronephrosis or renal failure.

How can I advocate for myself?

Rare diseases like Prune Belly Syndrome are often misunderstood by general practitioners. If your concerns are dismissed, bring documented records of your urinary history and request a referral to a specialist at a university-affiliated hospital. You can also connect with the 64 members of our Prune Belly Syndrome community at DiseaseMaps.org to share experiences and find expert-recommended clinics.
