What is the difference between Pyelectasis and hydronephrosis?

Keeping this in view, is Pyelectasis dangerous?
It is a relatively common ultrasound finding in fetuses and is three times more common in male fetuses. In most cases pyelectasis resolves normally, having no ill effects on the baby. The significance of pyelectasis in fetuses is not clear. Pyelectasis is considered to be a "soft marker” for Down syndrome.
Additionally, what is Pelviectasis on ultrasound? A. Fetal pelviectasis (also called pyelectasis or renal pelvis dilation) is a common finding on midtrimester ultrasound, occurring in 0.5% to 4.5% of fetuses. Pelviectasis is defined as a renal pelvic diameter 4 mm to 9.9 mm, and hydronephrosis as 10 mm or larger.
In this regard, does hydronephrosis mean Down syndrome?
In most cases, there are no other abnormalities. However, hydronephrosis can be seen more commonly in babies with Down syndrome. The risk of Down syndrome is thought to be low when there are no additional risk factors, such as abnormal ultrasound or maternal serum screening results).
What causes Pyelectasis?
The most common causes of pyelectasis are: Ureteropelvic junction obstruction: A blockage of urine between the kidneys and the ureter. Vesicoureteral reflux: An abnormal flow of urine from the bladder to the kidneys.
