In this lecture we review the approach to a patient with gross hematuria. Before you begin your evaluation think of the GU anatomy and build a differential of the possible causes of gross hematuria. From here figuring out what to ask on the history and what to look for on the physical will be easy. Consider your differential when ordering labs and be sure to always consider your wild cards. Use the algorithm in this lecture to understand when and when not to call urology. (10/18/18) https://www.blog.numose.com/emed-obgyn-uro/hematuria
