Uropathies diagnosed in the neonatal period: symptomatology and course.

Forty infants with a uropathy diagnosed during the first two months of life were studied. Presenting signs were urinary tract infection in one-half of the cases, disorders of micturition, pelvic or abdominal wall malformations, abdomino-pelvic mass, and macroscopic hematuria. Obstructive uropathy was observed in 17 children and vesicoureteric reflux in 29. We noted a high incidence of extrarenal malformations (14 of the 40 cases) in this series of uropathies diagnosed during the neonatal period. Despite early diagnosis, the course was not favorable in 11 cases with congenital anomalies of the renal parenchyma.
