Can girls have pyelectasis?

Pyelectasis is a collection of fluid in the fetal kidneys causing them to dilate. Pyelectasis is also referred to as “renal pelvic dilatation.” This iss seen in approximately 1% of pregnancies, and is more common in male than in female fetuses.

Is pyelectasis something to worry about?

Pyelectasis is a finding on an ultrasound examination and requires follow-up but not necessarily treatment as we have discussed. Frequently, the finding disappears by itself and does not have any negative impact on the baby.

Does pyelectasis mean Down syndrome?

Pyelectasis can indicate Down syndrome on an ultrasound; however, most babies with pyelectasis do not have Down syndrome.

Is pyelectasis genetic?

Compared with normal fetuses, those with pyelectasis had a relative risk of 6.1 to have a recurrence of this finding in their next pregnancy (95% confidence interval, 4.3-7.5, p < 0.001). These results suggest a predisposition for pyelectusis that may be influenced by genetic and/or environmental factors.

How common is fetal pyelectasis?

Pyelectasis is an increased collection of urine in part of the baby’s kidney called the renal pelvis. Approximately 1 in every 40 pregnancies have pyelectasis, and this can be seen in one or both of the kidneys. Pyelectasis can be seen in any pregnancy, but is more common in boys.

How serious is fetal pyelectasis?

A fetus with severe pyelectasis or hydronephrosis is at increased risk of developing problems such as low amniotic fluid and kidney disease. In addition pyelectasis has a weak association with chromosome abnormalities, in particular Down syndrome .

Is fetal pyelectasis serious?

How common is pyelectasis?

Is pyelectasis common?

When is a repeat prenatal scan indicated in the workup of pyelectasis?

Some advocate a repeat prenatal scan at 30-40 weeks gestation for fetuses if ≥6 mm of renal pelvic dilatation is detected prior to 28 weeks as well as postnatal follow-up for persistent pyelectasis 6). Postnatally, most cases with pyelectasis resolve spontaneously in the first year of life, and invasive procedures are not required.

When is fetal pyelectasis considered to be present?

According to the Society of Fetal Urology (SFU) consensus 15, fetal pyelectasis is considered present if the anterior to posterior diameter of the renal pelvis measures: 1 >4 mm up to 28 weeks#N#or 2 >7 mm at or after 28 weeks gestation More

What is the normal range of pyelectasis?

The amount of stretching of the renal pelvis with pyelectasis is typically defined as greater than 4 mm but less than 10 mm in a baby younger than 24 weeks of gestation. Enlargement of 4 to 10 mm also may be called mild hydronephrosis. In 90 percent of cases, this condition will improve by itself and never become hydronephrosis.

What is pyelectasis of the pelvis?

When the pelvis is stretched or enlarged, but not enlarged enough for doctors to diagnose hydronephrosis, it is considered pyelectasis. Pyelectasis also is known as renal pelvic dilatation.
