[Prenatal diagnois of uropathies. Ten case reports].
Obstructive uropathies are a frequent cause of child renal failure. The prenatal diagnosis of such abnomalities should lead to appropriate management.


OBJECTIVE
To evaluate the interest of ultrasonographic prenatal diagnosis of urinary tract malformations.


METHODS
Retrospective study of 10 cases of urinary tract malformations diagnosed in utero. The mean age of the patients was 34.9 years and the mean gestational age at the prenatal diagnosis was 28.2 weeks of amenorrhea. The abnormalities diagnosed were: 2 cases of ureteropelvic junction obstruction, 3 cases of posterior urethral valves and 5 cases of mild hydronephrosis. The fetal karyotype, realised in 8 cases, was normal. In one case the urinary abnormalities was part of a multiple malformation syndrome and led to the termination of the pregnancy. 7 cases had a post-natal follow-up: 5 had a surgical management and two new borns had transient pyelectasies. The prediction of postnatal renal function is made by ultrasonographic appearance of the kidney and the amniotic fluid. Although the analysis of fetal urine for the assessment of renal function leads to conflicting results, it seems that sodium and beta-2 microglobulin urinary rates provide useful informations.
