Cystic kidney disease cannot be cured, but early evaluation in children can be helpful to decrease problems. If your child has been diagnosed with kidney cystic disease, you may need to be tested. Some of the cystic kidney diseases in children are passed down from a parent.

Can a baby survive bilateral renal agenesis?

It is often detected on fetal ultrasound because there will be a lack of amniotic fluid (called oligohydramnios). When both kidneys are absent this condition is not compatible with life. 40% of babies with bilateral renal agenesis will be stillborn, and if born alive, the baby will live only a few hours.

Does enlarged kidney mean Down syndrome?

Less often, a dilated renal pelvis is an early sign of a more serious problem with the bladder, kidney, or ureter. Down syndrome: Some studies suggest a small chance for Down syndrome with this ultrasound finding.

Can hydronephrosis be cured in babies?

The exact cause of MCDK is often unknown. It may be due to a blockage in the flow of urine along its path out of the kidney very early in development. There are rare cases when MCDK is due to a genetic condition. However, most occur randomly and are not inherited.

When is Potter’s Syndrome Detected?

If not detected before birth (prenatally), then lack of urine production, specific (facial) features or difficulty breathing may be signs of Potter syndrome. A routine specialized imaging technique called a fetal ultrasound may detect Potter syndrome before birth.

What happens if a baby only has one kidney?

Many children with only one kidney have no symptoms or complications and do not need treatment. Sometimes the other kidney grows larger than normal to make up for the missing kidney. However, children may be at risk of urinary tract infections (UTIs) and/or hypertension (high blood pressure) later in life.

Pediatric Kidney Size Percentile Calculator. contributed by Michal Kulon, MD on 9/15/2015. For age of 0 years 0 months 0 days, the average kidney length is 4.43 cm and standard deviation is 0.29 cm. Right kidney length of 0 cm corresponds to 0 percentile (15.35 standard deviations below the mean).

Is it common for a baby to have one kidney?

It is quite a common – it is estimated that one baby in a few hundred will be born with one hypoplastic (small) kidney. If this affects one kidney, it is called unilateral renal hypoplasia. Many children with one small kidney do not have long-term problems, but may need to go back to the doctor for tests.

What happens if a child has a small kidney?

Many children with one small kidney do not have long-term problems, but may need to go back to the doctor for tests. If this affects both kidneys, it is called bilateral renal hypoplasia. This is more serious.

What happens if a child has unilateral renal dysplasia?

Sometimes children with unilateral renal dysplasia have an abnormality in the other kidney. If the other kidney does not work normally, your child may have reduced kidney function. He or she may be at greater risk of progressing to later stages of chronic kidney disease (CKD), and will need more monitoring.
