Hypercalciuria in Children

Hypercalciuria means there are high levels
of calcium in the urine. This can be checked
on a single urine sample, but is best checked
with a 24-hour urine test. The high level of
calcium in the urine is often caused by
increased absorption or a defect of the
kidneys. Increased levels of urine calcium
can cause kidney stones.

Hypercalciuria is treated by bringing the
urine calcium to normal levels. This lowers
the risk of getting kidney stones.

1. As part of your child’s work-up, we
will do blood tests and we may
suggest a 24-hour urine test to look
for risk factors leading to kidney
stones. The results of this test will
help us plan further treatment. We
will also do 24-hour urine tests 2 to 4
times a year to watch the level of
calcium in the urine.

2. A kidney (renal) ultrasound and
abdominal x-ray (KUB) may be
ordered to look for kidney stones.
These tests might be done every 12
to 18 months.

3. A low salt diet is a very big part of
the treatment to lower calcium in the
urine and prevent kidney stones.
Our nutritionist will be talking with
you about your child’s eating habits
to help lower their risk for kidney
stones.

Increasing fluids: Kidney stones are
more likely to form in urine that is
concentrated. By drinking more, your
child’s urine will be more diluted. This
will lower the risk of stones forming.

The goal for your child is to drink
___________oz. of water/fluids each
day. It is best to drink water, but all
fluids count. Some children use water
bottles to remind them to drink. You
may need to tell your child’s teacher that
your child needs to drink a lot of water
and may also need bathroom breaks
more often.

Decreasing salt: The salt in your diet is
linked to calcium in the urine. If the
amount of salt in the diet is lowered, the
amount of calcium in the urine will also
be lower.

The goal for your child is to have no
more than _____________mg of sodium
a day. Our kidney nutritionist can talk
with you about how you can lower salt
in your child’s diet.

Eating the right amount of calcium:
Your child’s high urine calcium levels
are not caused by eating too much
calcium. In fact, because your child is
losing calcium in the urine, most of this
comes from the bones. We want to be
sure that your child takes in enough
calcium in his daily diet, but not more
than is needed. The goal for your child
is to have _______mg of calcium a day.

4. Drugs are often used if your child
has a kidney stone or if the level of
calcium in the urine is high and does
not come down with fluid and diet
changes alone. Diuretics are the
most common types of drugs used.





Diuretics: Moduretic or
Hydrochlorothiazide are diuretics we
often use. These drugs help to lower the
amount of calcium in the urine. For 2-6
hours after taking the drug, your child
will have to go to urinate more often.
The kidneys will lose more potassium
with the use of these drugs. Because of
this, we suggest you increase the
potassium in your child’s diet.

We will be checking the level of your
child’s blood potassium about 2 weeks
after starting the diuretic and 2-3 times a
year. If your child has a low potassium
level our pediatric nutritionist will be
able to talk to you about increasing
potassium in the food you eat. If your
child’s potassium level is too low, we
may prescribe a potassium supplement.
