Fetal Renal Pyelectasis
No.: Fetal pyelectasis refers to borderline prominence of the renal collecting system and is defined as >4 mm by 20 weeks; >7 mm between 20-30 weeks and >8 mm after 30 weeks. It is seen in 3% of all pregnancies associated with polyhydramnios and diabetes mellitus. It is a very weak marker of increased risk for fetal down syndrome but never causes mortal risk. Neonatal follow-up is required! ...Read more

25wk fetal boy; us shows eif, and both dilated kidneys 5.2mm/5.8mm pyelectasis, normal quad screen testing, should I be worried? Is this serious?
On the fence. If : There were > 2 markers, especially if they included nuchal thickening ; hyperechoic bowel , your OB would have offered a genetic amniocentesis to rule out aneuploidy, an abnormal # of fetal chromosomes. Ask to see a fetal-maternal medicine specialist who can review fetal growth ; markers, do a super-high-tech fus ; maybe a fetal echocardiogram. Then make an informed decision about amnio. ...Read more
For my fetus, all my usg were normal till 30 weeks. Now at 32 weeks it shows that fetus has pyelectasis at 8.2 mm.Can pyelectasis develop so suddenly?
Fetal growth is fast: The fetus is constantly growing rapidly and logarithmically to become the little baby you get to see at the end of 9 months from being a single celled embryo. By 3 weeks many of the eyes, ears, and such are already developed. So, the rest is occurring at rapid pace. It's amazing how automatically the human fetus is programmed to develop perfectly as time moves on. There are even neonatal surgeons! ...Read more

Prenatal pyelectasis: Prenatal pyelectasis is common , the current reccomendation is to get postnatal ultrasound exam. Of the kidneys and bladder at 36-48 hours prior to discharge and repeat the exam at 4-6 weeks, if the dilation persist you should consult a pediatric urologist in your area , if the early (36 hrs) ultrasound study show bilateral hydronephrosis in a baby boy a voiding cystourethrogram is reccomended. ...Read moreSee 2 more doctor answers
No big deal.: Detecting renal problems by fetal ultrasound is very accurate and efficient because it can prevent serious complications postnatally. Fetal renal pyelectasis or even hydronephrosis is nothing to worry about, provided the amniotic fluid is monitored and remains normal. The neonatology team should be notified at birth to institute appropriate follow-up for the newborn; monthly ultrasounds are needed. ...Read moreSee 1 more doctor answer
At 20 week ultrasound, the baby's kidney showed renal pelvis dilation with calyceal dilation at 6 mm for both kidneys. There was no blockage in ureter. Opinions?
No question here: If you are asking "is there blockage in the ureter?" then the answer is possibly. Significant dilation in early gestation increases this risk. It is important to know that dilation (hydronephrosis) can occur without obstruction as well. If the amniotic fluid is low, see a pediatric urologist for prenatal consultation, particularly if you are having a boy (risk of urethral obstruction is high). ...Read moreSee 2 more doctor answers
