What is it like to have any experience with fetal pyelectasis?

Fluid in kidneys: The fetal pyelectasis is the dilation of the fetal renal pelvis. This dilation could be secondary to an obstructive process the the fetal urinary tract or a back flow of urine in the fetal urinary tract. Obstruction can occur at the level of the kidney, the ureter or the outlet of the bladder (urethra). The diagnosis is made by ultrasound during pregnancy. ...Read more

Can fetal pyelectasis be fatal?

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

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

What to do if I'm 36 wks preg, baby is diagnosed fetal hydronephrosis,renal pelvis measures 7.5cm,will she lose her kidney?

Do nothing now: Baby is almost certainly perfectly OK. If renal pelvis 7.5mm, nothing to worry about & will 99 - 100% settle down as a normal kidney. 7.5 cm is very large & will almost certainly require intervention. Will require:- pediatric urologist, post natal US , VCUG & nuclear scan after birth to evaluate swollen kidney for function. Removal only if no or essentially no function. Life with 1 kidney is OK. ...Read more

Fetal ultrasound showed enlarged renal pelvis and large head. So could it be a syndrome?

May or may not.: Enlarged renal pelvises are common urinary tract anomalies. A large head can be familial. So not likely. But then there is much ultrasound can't diagnose. Just have to wait and see. ...Read more

What to do if I'm 35 weeks pregnant and my ultrasound says mild polyhydramnios with bilateral fetal dilated renal calyces?

Talk to your doctor: Depending on other clinical factors, mild polyhydramnios and mild dilated calyces may be within normal limits, but could be markers for a high risk delivery and underlying fetal problems. This cannot be answered in a forum. Your doctor needs to evaluate all the parameters. ...Read more

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 more
