Abdomen Sonography: Urinary Masses (Kidneys) - Video Lesson

Hey, everyone. Welcome back to our series on abdominal extended sonography. In today's lesson, we'll explore urinary masses, focusing on the kidneys and ureters. We'll walk through key cystic and solid lesions including both benign and malignant types, pediatric considerations and how to differentiate them based on their sonographic appearance. Evaluating urinary masses is a critical part of abdominal sonography because early detection and accurate characterization of renal and ureteral lesions can directly influence patient management and outcomes. Let's get started. First, we are going to discuss the sonographic criteria for differentiating cystic versus solid lesions. The criteria for identifying cysts includes looking for anechoic areas with thin walls and posterior enhancement. Solid lesions on the other hand contain internal echoes, may have shadowing and or irregular borders and possible vascularity. It is important to use color Doppler when
