What to Do With Renal Cysts in Children?

Area of Science:

• Pediatric Urology
• Pediatric Nephrology
• Medical Imaging

Background:

• Renal cysts in children are a common clinical finding.
• Current management strategies lack international standardization.
• Variations exist in surveillance, imaging, and treatment protocols.

Purpose of the Study:

• To investigate current international practice patterns for pediatric renal cyst management.
• To identify consensus and discrepancies among pediatric urologists and nephrologists.
• To inform the development of standardized clinical guidelines.

Main Methods:

• International survey distributed to pediatric urologists and nephrologists.
• Survey included 21 questions and 4 clinical scenarios.
• Data analyzed using chi-square tests for interspecialty comparisons.

Main Results:

• 183 specialists responded; most (57%) supported an ultrasound-based Bosniak classification.
• Follow-up intervals varied: 6-12 months (urologists) vs. 1-2 years (nephrologists).
• Reasons for escalated surveillance included symptomatic mass effect, gross hematuria, and family history. Treatment for simple cysts varied, especially for modified Bosniak III cysts.

Conclusions:

• No international consensus exists for pediatric renal cyst management.
• An ultrasound-based Bosniak classification is widely considered reasonable.
• Development of registries and guidelines is crucial for standardized care and addressing associated malignancies.
