Symptoms:

• Club foot or abnormal limbs (rare)
• Undescended testicles
• Wrinkled skin on belly area

Signs and tests:

Expectant mothers carrying affected infants may have varying degrees of oligohydramnios (not enough amniotic fluid), which make the infant likely to have lung problems.

An ultrasound done during pregnancy may show that the baby has a swollen bladder or enlarged kidney.

In some cases, a pregnancy ultrasound may also help determine if the baby has:

• Heart problems
• Musculoskeletal abnormalities
• Stomach and intestinal problems
• Underdeveloped lungs

The following tests may be performed on the baby after birth to diagnose the condition:

• Blood tests
• Intravenous pyelogram (IVP)
• Ultrasound
• Voiding cystourethrogram (VCUG)
• X-ray
