Investigation of nephrolithiasis in the West of ParanĂ¡.
[cystinuria]
Nephrolithiasis
is
com
>
mon
and
has
a
high
rate
of
recurrence
.
To
assess
the
prevalence
of
the
main
metabolic
and
anatomical
changes
and
the
chemical
analysis
of
stone
found
in
patients
with
nephrolithiasis
in
the
West
region
of
ParanĂ¡
.
Retrospective
study
with
681
adult
patients
with
nephrolithiasis
.
The
laboratory
investigation
included
at
least
two
samples
of
24
-
hour
urine
test
with
doses
of
calcium
,
uric
acid
,
citrate
,
oxalate
,
sodium
and
creatinine
;
qualitative
cystinuria
,
urinary
pH
following
12
-
hour
fast
and
water
restriction
,
urine
culture
and
chemical
analysis
,
when
the
stones
were
available
.
Renal
imaging
techniques
included
at
least
renal
ultrasound
and
excretory
urogram
.
The
metabolic
changes
most
frequently
found
were
:
hypercalciuria
(
51
.
8
%
)
,
hyperuricosuria
(
27
.
6
%
)
,
and
hypocitraturia
(
23
.
5
%
)
.
Chemical
analysis
of
stones
showed
calcium
oxa
late
in
85
.
7
%
of
the
cases
.
The
most
frequently
anatomical
changes
were
renal
cyst
,
duplicated
ureter
,
and
ureteropelvic
junction
obstruction
.
This
paper
served
as
a
base
for
knowing
the
characteristics
of
patients
with
nephrolithiasis
in
the
West
area
of
ParanĂ¡
.
