Causes of Potter syndrome
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 contractures.
Oligohydramnios also stops development of the lungs, so the lungs do not work properly at birth.
Potter syndrome Symptoms
- Widely separated eyes with epicanthal folds, broad nasal bridge, low set ears, and receding chin
- Absence of urine output
- Difficulty breathing
Tests and Exams
A pregnancy ultrasound may show lack of amniotic fluid, absence of fetal kidneys, or severely abnormal kidneys in the unborn baby.
The following tests may be used to help diagnose the condition in a newborn:
Treatment of Potter syndrome
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.
Prevention of Potter syndrome
There is no known prevention.
