Prenatal evaluation and outcome of fetal obstructive uropathies.
Between January 1982 and January 1986, 76 pregnant women between 15 and 40 weeks of gestation were referred because of suspected fetal obstructive urinary tract pathology. A total of 14 high-level (ureter) and 17 low-level (urethral) obstructions were diagnosed. High-level obstructions were at the uretero-pelvic level in 11 and at the uretero-vesical level in 3 cases. Increased amniotic fluid volume was observed in 28 per cent. The survival rate was 86 per cent. In the 17 cases of urethral obstruction, oligohydramnios was present in 70 per cent, associated structural defects in 30 per cent, and abnormal karyotype in 6 per cent. Pregnancy was terminated because of progressive massive hydronephrosis in 41 per cent; intrauterine or neonatal death occurred in 47 per cent, resulting in a survival rate of only 12 per cent.
