Causes, incidence, and risk factors
In Potter syndrome, the primary problem is kidney failure. The kidneys fail to develop properly as the baby is growing in the womb. The kidneys normally produce the amniotic fluid (as urine).
Potter phenotype refers to a typical facial appearance that occurs in a newborn when there is no amniotic fluid. The lack of amniotic fluid is called oligohydramnios. Without amniotic fluid, the infant is not cushioned from the walls of the uterus. The pressure of the uterine wall leads to an unusual facial appearance, including widely separated eyes.
Potter phenotype may also lead to abnormal limbs, or limbs that are held in abnormal positions or
Oligohydramnios also stops development of the lungs, so the lungs do not work properly at birth.
- Widely separated eyes with
epicanthal folds, broad nasal bridge, low set ears, and receding chin
- Absence of urine output
- Difficulty breathing
Signs and tests
The following tests may be used to help diagnose the condition in a newborn:
X-ray of the abdomen X-ray of the lungs
Resuscitation at delivery may be attempted pending the diagnosis. Treatment will be provided for any urinary outlet obstruction.
This is a very serious condition, usually deadly. The short-term outcome depends on the severity of lung involvement. Long-term outcome depends on the severity of kidney involvement.
There is no known prevention.
