Question from the clinician: management of prenatal hydronephrosis

A guide to evaluating survey research methodology in pediatric urology

Surveys are one of the most common study designs in healthcare research. They are easy to undertake, have minimal cost and aim to obtain reliable and unbiased information from a population of interest. Surveys in pediatric surgery/urology are an effective tool for gathering information on clinical practices for rare and complex conditions that highlight information on their behavior, institutional disparities, and healthcare paradigms. This education article consists of using a published survey by one of the authors as an example to demonstrate both positive and negative aspects, including limitations, of survey design studies with the purpose of helping pediatric urologists develop a framework to create and critically appraise survey methodology. Using this approach, readers should be able to reliably discern the methodological quality of published surveys.
