[A clinical approach to renal cysts]

Area of Science:

• Nephrology
• Genetics
• Medical Diagnostics

Background:

• Kidney cysts are linked to various diseases, broadly categorized into hereditary and non-hereditary types.
• Hereditary renal cystic diseases include autosomal recessive (e.g., autosomal recessive polycystic kidney disease) and autosomal dominant forms (e.g., autosomal dominant polycystic kidney disease), as well as syndromic cysts.
• Non-hereditary renal cystic diseases encompass conditions like cystic dysplasia, simple cysts, and acquired cystic kidney disease.

Purpose of the Study:

• To present a rapid and accessible clinical approach for diagnosing renal cysts.
• To consolidate the classification of hereditary and non-hereditary renal cystic diseases.
• To highlight the growing importance of genetic studies in understanding and potentially treating kidney cyst-associated diseases.

Main Methods:

• Literature review and synthesis of existing classifications for renal cystic diseases.
• Clinical categorization based on genetic inheritance patterns (autosomal recessive, autosomal dominant) and non-hereditary origins.
• Identification of key diseases within each category, including specific examples like Polycystic Kidney Disease and Wilm's tumor.

Main Results:

• A clear distinction between hereditary (e.g., Autosomal Dominant Polycystic Kidney Disease) and non-hereditary renal cystic diseases.
• Sub-classification of hereditary diseases based on inheritance patterns and associated syndromes.
• Enumeration of various non-hereditary cystic conditions, including simple and acquired types.

Conclusions:

• A structured classification aids in the clinical management of kidney cysts.
• Genetic insights into renal cystic diseases are vital for developing future therapies.
• This review provides a practical framework for clinicians encountering renal cysts.
