Potter Syndrome Overview
Learn About Potter Syndrome
Potter syndrome and Potter phenotype refers to a group of findings associated with a lack of amniotic fluid and kidney failure in an unborn infant.
Potter phenotype; Potter's 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) that surrounds the unborn baby.
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.
Symptoms include:
- Widely separated eyes with epicanthal folds, broad nasal bridge, low set ears, and receding chin
- Absence of urine output
- Difficulty breathing
Resuscitation at delivery may be attempted pending the diagnosis. Treatment will be provided for any urinary outlet obstruction.

This is a very serious condition. Most of the time it is 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.
Summary: The goal of this clinical trial is to learn if serial amnioinfusions can improve the chances of survival for fetuses with severe kidney problems that cause low amniotic fluid (anhydramnios). Low amniotic fluid can affect lung development and may lead to serious health issues for the fetus. The main questions this study aims to answer are: * Can serial amnioinfusion increase the chances of survival...
Summary: Early pregnancy renal anhydramnios or EPRA is a condition where a pregnant woman does not have any amniotic fluid around her fetus because of a problem with the fetus's kidneys. This condition is thought to be fatal once the fetus is born because of inadequate lung growth. The Renal Anhydramnios Fetal Therapy (RAFT) Trial offers eligible pregnant women with a diagnosis of EPRA an experimental ther...
