In this lecture, Professor Zach Murphy breaks down Urinary Tract Infections with a clear, high-yield approach focused on recognition, diagnosis, and management. This video builds a practical framework for understanding how urinary tract infections develop, how to distinguish lower from upper tract disease, and how to identify patients at risk for complicated infection.
We begin with pathophysiology and microbiology, emphasizing ascending infection of the urinary tract, common pathogens such as Escherichia coli, and the major risk factors that predispose patients to infection, including urinary obstruction, catheterization, sexual activity, and anatomic abnormalities.
Next, the lecture covers clinical presentation, focusing on the key differences between cystitis and pyelonephritis. You will learn to recognize classic lower urinary symptoms such as dysuria, urgency, and frequency, as well as systemic findings like fever, flank pain, nausea, and costovertebral angle tenderness that suggest upper urinary tract involvement.
The session then focuses on diagnosis and complications, including interpretation of urinalysis and urine culture findings, indications for imaging, and important complications such as renal abscess, sepsis, and recurrent infection.
