Abstract
OBJECTIVE: To explore the current practice patterns for the management of renal cysts internationally among pediatric urologists and nephrologists.
MATERIALS AND METHODS: A survey composed of 21 questions and 4 clinical scenarios was distributed to pediatric urologists and nephrologists. Survey questions evaluated optimal imaging modality, management, and follow-up period. Interspecialty comparisons were made using chi-square analysis where appropriate.
RESULTS: A total of 183 respondents completed the survey (128 pediatric urologists, 37 pediatric nephrologists, and 19 other specialists). Most (57%) respondents agreed or strongly agreed with using an ultrasound based Bosniak classification to categorize renal cysts in children. The most commonly used follow-up intervals were 6-12 months for pediatric urologists and 1-2 years for pediatric nephrologists. Symptomatic mass effect (80.9%), gross hematuria (79.2%), or family history were the most common reasons for escalating surveillance. Pediatric nephrologists were more likely to increase follow-up with development of bilateral simple renal cysts (P = .008) or chronic kidney disease (P = .027) when compared to pediatric urologists. Laparoscopic marsupialization (39.4%) was the most common treatment for a simple renal cyst in a symptomatic child. Modified Bosniak III cysts had more heterogeneity in treatment based on the physician responses.
CONCLUSION: There is currently no consensus on the optimal protocol for the surveillance, imaging, or treatment of renal cysts in children. Most respondents agree that using an ultrasound-based Bosniak classification is reasonable. A call to action is therefore necessary for the development of registries and guidelines on the management of pediatric renal cysts and their associated malignancies.
