“Potter&;s syndrome” is associated with
**Core Concept**
Potter's syndrome is a rare congenital disorder characterized by bilateral renal agenesis, leading to oligohydramnios, and subsequent pulmonary hypoplasia, facial deformities, and other systemic anomalies. This condition is often associated with severe fetal distress and high perinatal mortality rates.
**Why the Correct Answer is Right**
The correct association of Potter's syndrome is with bilateral renal agenesis, which is the absence or underdevelopment of both kidneys. This results in a significant reduction in the production of amniotic fluid, causing oligohydramnios. The decreased amniotic fluid volume impairs fetal lung development, leading to pulmonary hypoplasia. Additionally, the decreased amniotic fluid volume can cause the fetal skin to become wrinkled and the facial features to become distorted, resulting in characteristic facial deformities.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while Turner syndrome is a genetic disorder that affects females, it is not directly associated with Potter's syndrome.
**Option B:** This option is incorrect because while bilateral renal agenesis is a hallmark of Potter's syndrome, it is not the only condition associated with this finding. Other conditions, such as renal dysplasia or obstructive uropathy, can also cause bilateral renal agenesis.
**Option C:** This option is incorrect because while pulmonary hypoplasia is a common finding in Potter's syndrome, it is not the primary cause of the condition.
**Option D:** This option is incorrect because while facial deformities are a characteristic feature of Potter's syndrome, they are not the primary association.
**Clinical Pearl / High-Yield Fact**
To remember the association of Potter's syndrome with bilateral renal agenesis, recall that the "P" in Potter's syndrome stands for "pyelectasis" (dilatation of the renal pelvis), which is a common finding in this condition.
**Correct Answer:** C.
