Abdomen Sonography: Urinary Infections - Video Lesson

Hey everyone, welcome back to our abdominal extended sonography series. In today's lesson we're focusing on urinary tract infections. We will look at the sonographic features of renal and bladder infections, and how to differentiate these conditions based on their appearance, clinical significance and severity. As a sonographer, understanding what's normal, what's abnormal and what's urgent helps you confidently guide the clinical team and contribute to timely, effective care. Let's dive in! Let's start with Acute pyelonephritis, one of the most common upper urinary tract infections. It's usually caused by a sending bacterial infection from the bladder, often E. Coli, and typically affects women more than men. On ultrasound, acute pyelonephritis may present as an enlarged kidney with decreased or patchy echogenicity. In some cases, you may notice loss of the normal cortico medullary differentiation, and in focal cases, a hypoechoic, wedge shaped area of inflammation.
