The most common cause of fetal bowel obstruction is due to a meconium plug.

Echogenic bowel is linked to all of the following EXCEPT:

If multicystic dysplastic kidney disease is bilateral, what are the associated sonographic findings?

What is the most common cause of fetal bowel obstruction?

A fetal sonogram reveals a lower abdominal wall mass inferior to the umbilicus, absence of the urinary bladder, and normal amniotic fluid. What disorder does this represent?

A male fetus is demonstrated to have bilateral hydronephrosis with hydroureter, dilated bladder, and dilated urethra. What is the likely cause of these findings?

Omphalocele has higher risk for heart defects and chromosomal anomalies than gastroschisis.

How is the level of echogenicity of bowel determined?

A fetal sonogram demonstrates a normal left kidney but the right has a severely dilated renal pelvis and dilated proximal ureter, the rest of the urinary system is normal. What is the most likely cause?
