Fetal Renal Pyelectasis
Ask your OB: I assume they have done the proper testing , most babies that have pyelectasis which is not totally uncommon do not have ds but if u are worried please discuss with your obgyn. ...Read more
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
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
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
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
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
I did my 36w ultrasound and found left fetal renal pelviectasis with 7.7mm. What causes it?Does my son need test for any infection such as toxoplasma?
Incidental finding: As the kidneys form the central collecting area may appear large on prenatal ultrasound. This is during a time when most kidney functions are done by mom/placenta. Within the first 4-6 weeks after birth this finding often disappears as the kidney begins its normal work. It would need a follow-up ultrasound after birth but I wouldn't assume something bad. It is not an infectious process. ...Read moreSee 1 more doctor answer
Dr plese tell if it is risky to deliver normally for baby & mother when the foetus is detected with renal pyrlectasis. Do it pressurize kidneys.?
Safe: Yes it is safe to delivery normally with this situation. There are no risks to either baby or the mother. ...Read more
Healthy diet.: Human fetal growth relies on many factors, most of which are not modifiable (e.g. Genetic material, placental function). Some others are, namely healthy diet, avoidance of smoking cigarettes and euglycemia. The curve attached shows how the human fetus grows exponentially near the end of the pregnancy - so another thing you can do to help your fetus grow is to avoid stress and reach your due date. ...Read more
Some thoughts: 26 million americans have some from of kidney disease. Typically the cause of this is related to a history of diabetes or hypertension. Other kidney diseases, although less common includes those related to kidney stones, genetic diseases (polycystic kidney disease), intrinsic kidney diseases (glomerularnephritis) etc. Great question! ...Read more
Ultrasound: You will need to have an ultrasound to know the gender of the fetus. You can also do an amniocentesis which is more invasive but more accurate and definitive to get a DNA test for sex determination. I am not sure if that is necessary unless you have a family history of genetic disorder that is related to sex of the baby. ...Read more
Thought to be safe: Mesalamine, or pentasa, (mesalamine) is thought to be one of the safer forms of medication for controlling ulcerative colitis or chrons in pregnancy. There are no known negative effects on the fetus. Sometimes rectal Mesalamine can be used for lower systemic dosing. ...Read moreSee 1 more doctor answer
Your Obstetrician: May suspect the fetus is measuring small for your gestational age on the basis of physical examination. An ultrasound may be ordered to assess size and growth. Fetal biometry, which includes measurements of the fetal head, abdomen and femur, is used to measure the fetus, and these numbers are compared to the expected size based on established gestational age. ...Read more
Physiology: This is one more way to see how good a person's kidney function is, to decide for example whether they can be a donor. A person may be given a radioisotope and their ability to clear it measured before and after they take a protein meal. It's a test of the ability of the kidney to increase its filtration rate (as when stimulated by a protein load.) ask a nephrologist how useful it is. ...Read moreSee 1 more doctor answer
