A *Staphylococcus aureus* urinary tract infection is an uncommon microbial infection of the renal and urologic system caused by the Gram-positive bacterium *Staphylococcus aureus*

It predominantly affects hospitalized individuals, older adults in long-term care settings, and patients with indwelling urinary catheters, structural abnormalities, or recent urological instrumentation Clinically, it manifests with standard lower or upper tract features—such as dysuria, urgency, suprapubic discomfort, or flank pain and fever—accompanied by bacteriuria and pyuria, with significant risks for complicated disease, abscess formation, and secondary staphylococcal bacteremia

Unlike typical ascending enteric infections, its pathophysiology frequently involves secondary hematogenous seeding to the kidneys from a distant focus or bloodstream infection, though primary ascending infection can also occur

Clinically, it manifests with standard lower or upper tract features—such as dysuria, urgency, suprapubic discomfort, or flank pain and fever—accompanied by bacteriuria and pyuria, with significant risks for complicated disease, abscess formation, and secondary staphylococcal bacteremia
