[Demographic, clinical and laboratory data of patients with urinary lithiasis in Fortaleza, Ceará].
[cystinuria]
To
describe
the
demographic
,
clinical
and
laboratory
data
of
patients
with
urolithiasis
in
Fortaleza
,
Ceará
,
Brazil
.
Secondary
data
were
collected
from
the
medical
records
of
197
patients
with
urolithiasis
,
during
the
period
1996
-
2006
.
Clinical
evaluation
and
24
-
h
urine
collection
for
measurements
of
urinary
volume
,
creatinine
,
calcium
,
phosphorous
,
uric
acid
,
sodium
,
potassium
and
magnesium
were
performed
.
Density
and
pH
value
were
determined
in
a
first
-voided
morning
urine
sample
.
Cystinuria
was
detected
by
stone
and
/
or
crystal
analysis
.
The
male
/
female
ratio
was
1
:
1
.
7
.
The
average
age
of
symptom
onset
was
35
.
8
±
13
.
3
years
,
with
no
significant
difference
between
the
genders
.
The
most
affected
age
range
was
20
-
39
years
(
56
.
3
%
)
.
Patients
reported
renal
colic
(
72
.
4
%
)
,
emergency
room
attendance
(
69
.
5
%
)
,
a
single
episode
of
lithiasis
(
46
.
7
%
)
or
recurrent
episodes
(
53
.
3
%
)
.
The
right
kidney
was
most
often
affected
in
women
(
44
.
4
%
)
,
while
men
suffered
predominantly
from
bilateral
lithiasis
(
39
.
7
%
)
.
The
main
metabolic
changes
observed
were
hypernatriuria
(
80
.
7
%
)
,
hypercalciuria
(
48
.
7
%
)
,
hyperuricosuria
(
17
.
3
%
)
,
and
cystinuria
in
5
patients
(
2
.
5
%
)
.
The
average
pH
value
and
density
were
5
.
74
±
0
.
59
and
1015
.
6
±
7
.
1
,
respectively
.
Urinary
volume
was
low
in
43
%
of
the
cases
.
Lithiasis
was
most
prevalent
in
adults
aged
20
-
39
years
,
and
affected
predominantly
women
in
our
region
.
The
most
frequent
metabolic
changes
,
in
descending
order
,
were
hypernatriuria
,
followed
by
hypercalciuria
and
hyperuricosuria
,
associated
with
low
fluid
intake
.
