MARTINEZ-OLMEDO, José L. et al. Prenatal diagnosis of urinary tract malformations: postnatal evaluation and clinical outcome. Perinatol. Reprod. Hum. [online]. 2023, vol.37, n.2, pp.43-53.  Epub 02-Oct-2023. ISSN 2524-1710.  https://doi.org/10.24875/per.23000004.

Background:

Urinary tract malformations represent 15-20% of abnormalities in prenatal ultrasound; the prevalence oscillates between 3-6 per 1000 births.

Objective:

To know the clinical outcome of newborns diagnosed prenatally with some malformation of the urinary tract.

Material and methods:

Observational, analytical, ambispective. Newborns with prenatal diagnosis of malformation urinary. Postnatal evaluation diagnostic tests performed, we analyzed the days of hospital stay, surgical intervention, follow-up.

Results:

45 children, 55% male, 65% term, 77% c-section. Prenatal diagnosis with higher frequency was hydronephrosis. In all cases postnatal renal ultrasound was performed, 27% voiding cystogram, 42% renal gammagram. A 60% of the cases required prolonged hospital stay, 27% required a surgical intervention, 60% were follow-up. 89% of the cases diagnosed prenatally corroborated some type of malformation of the urinary tract, only in 75% of the cases was the same diagnosis.

Conclusion:

Postnatal evaluation always requires the performance of a renal ultrasound and not in all cases the performance of voiding cystogram or renal gammagram.
