Complicated E. coli UTI

A complicated *Escherichia coli* urinary tract infection (UTI) is a symptomatic bacterial infection of the urinary tract caused by the Gram-negative pathogen *E. coli* that occurs in the context of host factors increasing the likelihood of treatment failure or serious complications It affects the lower or upper urinary tract, often involving patients with anatomical or functional genitourinary abnormalities, indwelling catheters, male sex, pregnancy, advanced age, or systemic immunocompromise

Clinically, it presents with dysuria, urinary frequency, or urgency alongside systemic features such as fever, rigors, flank pain, or costovertebral angle tenderness

Pathophysiologically, uropathogenic *E. coli* invades the urothelium and overcomes compromised host defenses, which carries an elevated risk of tissue invasion, pyelonephritis, perinephric abscess formation, and urosepsis
