Antenatal detection of renal abnormalities

Area of Science:

• Perinatal Medicine
• Fetal Imaging
• Pediatric Nephrology

Background:

• Prenatal diagnosis of congenital renal abnormalities is crucial for effective management.
• Routine ultrasonography plays a role in identifying potential fetal anomalies.
• Assessing the diagnostic value of prenatal ultrasound for renal conditions is essential.

Purpose of the Study:

• To evaluate the efficacy of routine prenatal ultrasonography in detecting renal abnormalities.
• To determine the correlation between prenatal ultrasound findings and postnatal diagnoses.
• To assess the impact of prenatal ultrasound on pregnancy management decisions.

Main Methods:

• Retrospective analysis of 29 pregnancies with suspected renal abnormalities over a two-year period.
• Routine prenatal ultrasound screening at 18-20 weeks gestation.
• Monthly or fortnightly follow-up ultrasounds for suspected anomalies.
• Postnatal evaluation including renal ultrasonography and histological/postmortem examination for non-survivors.

Main Results:

• 53% of suspected cases showed confirmed postnatal renal anomalies.
• Diagnoses in survivors included pelvi-ureteric junction obstruction, renal dysplasia, and vesicoureteric reflux.
• 14 infants with pelvicalyceal dilatation had normal postnatal ultrasounds, indicating a need for further investigation.

Conclusions:

• Abnormal prenatal ultrasound findings are valuable indicators of postnatal renal disease.
• Prenatal screening aids in pregnancy management decisions.
• Further collaborative studies are required to establish the significance of pelvicalyceal dilatation detected prenatally.
