[Cystic and hyperechogenic kidneys in children]

Area of Science:

• Pediatric Nephrology
• Prenatal Diagnosis
• Medical Genetics

Background:

• Cystic kidneys and obstructive uropathies represent the most frequent renal anomalies detected prenatally via ultrasound.
• These conditions carry significant genetic and clinical implications, necessitating early identification.
• Common causes include autosomal dominant/recessive polycystic kidney diseases and TCF2 gene-related anomalies, alongside syndromes like tuberous sclerosis.

Purpose of the Study:

• To highlight the importance of recognizing common prenatal renal anomalies.
• To emphasize the diagnostic approach for these conditions.
• To underscore the benefits of improved classification for tailored patient management.

Main Methods:

• Diagnosis relies on sonographic and morphological analysis of renal abnormalities.
• Evaluation includes a thorough family history assessment.
• Identification of extra-renal manifestations is also a key component.

Main Results:

• Prenatal ultrasound is effective in identifying frequent renal anomalies such as cystic kidneys and obstructive uropathies.
• A spectrum of genetic conditions, including polycystic kidney diseases and TCF2-linked anomalies, are associated with these findings.
• Syndromic associations with renal cysts are also noted.

Conclusions:

• Accurate diagnosis of prenatal renal anomalies is essential for understanding their genetic basis and clinical course.
• A comprehensive diagnostic strategy combining imaging, family history, and assessment for systemic involvement is crucial.
• Enhanced classification of affected patients facilitates personalized follow-up and optimized care strategies.
