Pyelectasis is a dilation of the renal pelvis. 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.
Kay recommends that a neonate born with untreated in utero hydronephrosis receive a renal ultrasound within two days of birth. A renal pelvis greater than 12 mm in a neonate is considered abnormal and suggests significant dilation and possible abnormalities such as obstruction or morphological abnormalities in the urinary tract.

Bladder outlet obstruction can be identified during routine prenatal ultrasonography as dilation of the fetal urinary tract [3] and decreased amniotic fluid levels. If dilation of the fetal urinary tract is suspected during pregnancy, an ultrasound of the infant's kidneys and bladder should be obtained after birth.
The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound. US is an accessible, versatile inexpensive and fast aid for decision-making in patients with renal symptoms and for guidance in renal intervention. [1] Renal ultrasound (US) is a common examination, which has been performed for ...
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
Multicystic dysplastic kidney (MCDK) is a condition that results from the malformation of the kidney during fetal development. The kidney consists of irregular cysts of varying sizes. Multicystic dysplastic kidney is a common type of renal cystic disease, and it is a cause of an abdominal mass in infants. [5]
"The tech just said, 'Hey, look at that. There's her two fingers,' and we all looked and just started laughing about what was happening," Kyle Weener told Yahoo Life.
The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [ 15 ] [ 16 ] [ 17 ] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics.
