Hydronephrosis is one of the most commonly identified prenatal anomalies, and the severity may vary from mild to severe, depending on the underlying cause, many of which stem from disruptions in the formation of the renal collecting system. Permanent renal damage may occur if the condition progresses before birth, and in some cases, oligohydramnios may result in lung hypoplasia, a potentially fatal condition. Many cases resolve spontaneously before birth, but for those that do not, the…

Postnatal imaging of neonates with prenatally diagnosed genitourinary abnormalities: a practical approach
TLDR
A practical approach to postnatal imaging of the neonate is discussed and the important genitourinary anomalies in this age group are presented and illustrated.
Urological Imaging in the Newborn
TLDR
Sometimes neonatal magnetic resonance imaging (MRI) can be very helpful to further evaluate complex urinary tract anomalies but is not used unless other techniques are insufficient to define the abnormality or to evaluate extent of disease, such as in neonatal neoplasms.
Neonatal imaging evaluation of common prenatally diagnosed genitourinary abnormalities.
TLDR
US remains the first-line imaging modality for evaluating the genitourinary system during the neonatal period and may be enhanced with the use of focused, high-resolution linear images of the pyramids, providing a powerful combination for morphologic and functional assessment.

Management of neonatal hydronephrosis.
Management of fetal hydronephrosis
TLDR
Prenatally detected hydronephrosis has become a common diagnosis and management involves a regimen of ultrasounds, voiding cystourethrograms, and nuclear renograms for diagnosis and surveillance.
Antenatal Hydronephrosis as a Predictor of Postnatal Outcome: A Meta-analysis
TLDR
Overall, children with any degree of antenatal hydronephrosis are at greater risk of postnatal pathology as compared with the normal population, indicating that comprehensive postnatal diagnostic management should be performed.
Outcome of isolated antenatal hydronephrosis: a systematic review and meta-analysis
TLDR
It is concluded that in patients with IAHN and lesser degrees of pelvic dilatation, pelvic diameter decreases to the normal range or does not worsen with the vast majority of patients.
Postnatal follow-up of antenatal hydronephrosis: a health-care challenge
TLDR
The absence of traditional barriers for compliance highlights the need to explore new ways of improving postnatal follow-up of infants with ANH, and the antepartum program for diagnosis of ANH is accessible and efficient.
The postnatal management of hydronephrosis diagnosed by prenatal ultrasound.
Optimal timing of initial postnatal ultrasonography in newborns with prenatal hydronephrosis.
TLDR
The degree of hydronephrosis varied between scans performed in the first 48 hours and 7 to 10 days of life in most newborns but this difference was not clinically significant at further followup.
Long-term follow up of antenatally diagnosed megaureters.
