| description | Background: Congenital abnormalities of the
urinary system are among the most commonly
diagnosed ones during prenatal sonographic
examinations. Obstructive uropathies represent
the major part of fetal urologic abnormalities.
Methods: The retrospective study included a
group of neonates in whom isolated obstructive
uropathies were found and consequently studied
in Tertiary Ultrasound Center at the Department
of Perinatology in Ljubljana since January 2002
to December 2006. The types and frequencies of
isolated obstructive uropathies were described,
the findings before and after birth were compared
and the positive predictive value of sonographic
measurement was calculated.
Results: 52 neonates, all singletons, were included.
The group consisted of 32 (61.5 %) boys
and 20 (38 %) girls. There were 21 pyelectasies
and 8 hydronephroses. The findings matched
completely in 22 (42.3 %) cases and partially in
28 (53.8 %) cases. In 2 (3.8 %) cases the findings
did not match. We found spontaneous improvement
after birth in 18 (62.1 %) cases. The calculated
positive predictive value of sonographic examination
during pregnancy in our Department
equaled 82.7 %.
Conclusions: Sonographic examination of the
fetal urinary tract has a good positive predictive
value (82.7 %). Obstructive uropathies appear
more often in boys (61.5 %). The clinical course
is better in boys as spontaneous improvement of
isolated renal pelvis dilatation occurs in 77.8 % of
boys and 36.4 % of girls. Mostly only one or two
sonographic follow-up examinations in the third
trimester of pregnancy are sufficient. Karyotyping
is not necessary with isolated obstructive
uropathies. |
