Cystic kidney disease presenting in infancy.

Area of Science:

• Pediatric Nephrology
• Medical Imaging
• Genetic Disorders

Background:

• Severe renal cystic disease in infants is a complex condition.
• Early diagnosis is critical for management and prognosis.
• Ultrasound is a primary imaging modality for detecting renal abnormalities in neonates.

Purpose of the Study:

• To review clinical, histological, and imaging findings in infants with severe renal cystic disease.
• To evaluate the diagnostic utility of various investigations, including ultrasound and intravenous urography.
• To assess the diagnostic yield of parental ultrasound in identifying underlying genetic causes.

Main Methods:

• Retrospective review of 12 infants diagnosed with severe renal cystic disease in their first year of life.
• Analysis of clinical data, renal biopsies, and imaging studies (ultrasound, intravenous urography).
• Inclusion of parental ultrasound findings for genetic correlation.

Main Results:

• A heterogeneous group of disorders was identified, including cystic dysplasia, autosomal dominant polycystic disease, autosomal recessive polycystic disease, and specific malformation syndromes.
• Renal sonography alone was insufficient for specific diagnosis or prognosis.
• Parental ultrasound proved to be the most valuable imaging procedure for establishing a diagnosis.

Conclusions:

• Severe renal cystic disease in infants represents a common pathway for diverse underlying conditions.
• Diagnosis and prognosis cannot be solely determined by infant renal sonography or intravenous urography.
• Parental ultrasound is essential for accurate diagnosis and should be performed in all suspected cases.
