An uncommon cause of acute kidney injury in young children: cystinuria.
[cystinuria]
Bilateral
obstructive
nephrolithiasis
is
a
rare
cause
of
acute
kidney
injury
(
AKI
)
in
early
childhood
.
As
soon
as
the
identification
of
AKI
secondary
to
ureteral
stone
is
made
,
it
will
necessitate
an
emergency
treatment
.
We
report
three
infants
with
AKI
caused
by
bilateral
obstructive
ureteral
cystine
stones
.
They
were
diagnosed
with
acute
post-
renal
injury
due
to
obstructive
bilateral
ureteral
stones
based
on
ultrasound
scan
findings
.
Immediately
,
bilateral
ureteral
stents
were
inserted
for
urinary
drainage
.
Once
renal
function
recovered
to
normal
,
each
patient
underwent
ureteroscopy
and
percutaneous
nephrolithotomy
at
the
same
session
.
Cystinuria
was
diagnosed
by
stone
analysis
and
increased
urinary
excretion
of
cystine
.
Patients
were
advised
to
maintain
a
high
fluid
intake
and
were
treated
with
potassium
citrate
in
addition
to
tiopronin
.
With
these
three
cases
we
would
like
to
emphasize
the
importance
of
urolithiasis
in
the
differential
diagnosis
of
acute
renal
failure
in
young
children
,
since
urolithiasis
may
only
cause
nonspecific
symptoms
in
this
population
.
An
early
diagnosis
with
prompt
treatment
and
a
close
follow-up
are
the
key
for
achieving
the
best
long
-term
outcome
in
cystinuria
.
