Kidney Disorder During Pregnancy
Often, pregnancy does not cause
a kidney disorder to worsen.
Usually, kidney disorders worsen only in pregnant women who have high
blood pressure that is not well-controlled. If pregnant women have a
kidney disorder, they are more likely to develop high blood pressure,
including preeclampsia (a type of high blood pressure that develops
during pregnancy)
Having a before becoming pregnant
increases the risk that the fetus will not grow as much as chronic kidney
disorder expected or be stillborn. Having a severe kidney disorder usually
prevents women from carrying a baby to term.
In pregnant women who have a kidney
disorder, kidney function and blood pressure are monitored closely, as is
growth of the fetus. If the kidney disorder is severe, women may need to be
hospitalized after 28 weeks of pregnancy so that bed rest is guaranteed, blood
pressure can be controlled well, and the fetus can be monitored closely.
Women who have had a kidney
transplant are usually able to safely give birth to healthy babies if they
have all of the following:
·
A transplant that has been in place for 2 or more years
·
Normal kidney function
·
No episodes of rejection
·
Normal blood pressure
Women who have a kidney disorder that
regularly requires hemodialysis are often at high risk of pregnancy
complications, including miscarriage, stillbirth, preterm birt,
and preeclampsia. But because of advances in dialysis treatment, up to 90% of
babies born to these women survive.
Usually, delivery is required before
the due date because the woman develops preeclampsia or the fetus is not
growing as much as expected. Doctors may remove and analyze a sample of the
fluid that surrounds the fetus (amniotic fluid). This procedure,
called amniocentesis, helps doctors determine whether the fetus’s lungs
are mature enough to breathe air and thus when the baby can be delivered
safely.
Cesarean delivery is often done,
but sometimes vaginal delivery is possible.
