2.  The prune belly syndrome is a rare anomaly
comprising a specific constellation of features. It
consists of three major findings :
1. Gross ureteric dilatation
2. Anterior abdominal wall underdevelopment
(resulting in the "prune belly" appearance)
3. Bilateral undescended testes .
There is often an association with other respiratory,
gastrointestinal, musculoskeletal, and
cardiovascular anomalies.

3. FETAL ABDOMEN
FETAL
SPINE
An ultrasound examination
that reveals a dilated
bladder and/or fetal
ureters, a distended fetal
abdomen, and
oligohydramnios, either
alone or in combination,
should alert a physician to
the possibility of Prune-
Belly syndrome.

8. A partial or complete lack of abdominal

covering the abdomen.
Undescended testis in males
Urinary tract abnormality such as unusually
large ureters, distended bladder,
accumulation and backflow of urine from the
bladder to the ureters and the kidneys
Frequent urinary tract infections due to the
inability to properly expel urine.
Later in life, a common symptom is post-
ejaculatory discomfort. Most likely a bladder
spasm, it lasts about two hours.

9. Prune belly syndrome is
a rare, genetic birth
defect affecting about 1

97% of those affected
are male. Prune belly
syndrome is a
,congenital disorder of
the urinary system
characterized by a triad
of symptoms.
