What does enlarged kidney in fetus mean?
Fetal hydronephrosis is swelling of a baby’s kidney caused by a buildup of urine. This can happen while the baby is still in the mother’s uterus.

This can occur from a blockage in the tubes that drain urine from the kidneys (ureters) or from an anatomical defect that doesn’t allow urine to drain properly.
What is the risk of Down syndrome with fetal pyelectasis?
Although Down syndrome can occur in any pregnancy, the chance for Down syndrome increases with the mother’s age. When pyelectasis is seen on ultrasound, the risk for Down syndrome is approximately one and one-half (1.5) times a woman’s age-related risk.
What is the treatment for an enlarged kidney?
Antibiotics are prescribed for the treatment of an enlarged kidney due to pyelonephritis .
What causes an enlarged kidney?

What are the causes of kidney dilation in a fetus?
The most common reason for fetal kidney dilation is an obstruction of some type. Doctors at Wayne State University’s Department of Urology explain that it “is not uncommon to see dilation of the kidney drainage system of a fetus before birth” and that most blockages are found at the beginning of the tube that connects the kidney and bladder.
What does a slightly enlarged kidney mean?
An enlarged kidney is a condition in which a kidney is larger than its normal size. Generally, kidney enlargement is a symptom of an underlying disease or disorder of the kidneys. Some common illnesses that may cause this to occur include polycystic kidney syndrome, a kidney stone and unilateral hydronephrosis.
Why would my 20 week baby have dilated kidneys on an ultrasound?
In some cases, one or both kidneys may fail to develop. In other instances, an abnormality may be present that blocks the outflow of urine. This blockage may cause urine to back up into the kidney, a condition called hydronephrosis, which causes the kidney to appear enlarged on the ultrasound test.
How common is enlarged kidney fetus?
Hydronephrosis is usually diagnosed in one of two ways. 1) A prenatal ultrasound (ultrasound during pregnancy) may reveal a fetus with dilated kidneys. This occurs in 1 per 100 pregnancies.
Is fetal hydronephrosis serious?
The severity of fetal hydronephrosis depends on how large the kidney has ballooned and the extent of the blockage. If not corrected, it can cause the kidney to lose its ability to make urine. True hydronephrosis is, therefore, a major concern.
How is an enlarged kidney treated?
Treatment depends on the cause of the kidney swelling. Treatment may include: Placing a stent (tube) through the bladder and ureter to allow urine to flow from the kidney into the bladder. Placing a tube into the kidney through the skin, to allow the blocked urine to drain out of the body into a drainage bag.
How long does it take for a swollen kidney to heal?
Kidney function will begin decreasing almost immediately with the onset of hydronephrosis but is reversible if the swelling resolves. Usually kidneys recover well even if there is an obstruction lasting up to 6 weeks.
Can severe fetal hydronephrosis correct itself?
About Fetal Hydronephrosis In half of all cases, the condition resolves on its own by the third trimester. If the condition persists, it usually improves after childbirth without treatment.
How is fetal hydronephrosis treated?
Treatment involves surgery, either major or minor, to correct whatever is causing the blockage of urine or to repair the valve-like structures of the ureter to prevent backflow of urine from the bladder.
Can a 20 week scan show enlarged kidney?
This is one of he most common things they find at the 20 week scan, the majority of the time it corrects itself after baby is born. You will more than likely just have to have monthly ultrasounds to monitor the growth of the kidney The limit for diagnosis of mild renal dilation is 4mm or above before 32 weeks and 7mm -10 mm after.
What did the ultrasound show at 19 weeks?

When did my daughter have her renal ultrasound?
Two days after she was born she had a renal ultrasound. Today we see a pediatric urologist and they are performing more tests to get a better picture of her anatomy. It sounds scary but she is the happiest, easiest little girl. You would never know anything is wrong. She pees normally and has no fussiness issues.
Is it normal to have kidney dilation at 32 weeks?
The limit for diagnosis of mild renal dilation is 4mm or above before 32 weeks and 7mm -10 mm after. It’s the most commonly diagnosed “abnormality”. I would not worry, the measurement is done with a curser on an ultrasound, if it was 3.98mm you’d be in the normal range.
