Complicated Proteus UTI

A complicated Proteus urinary tract infection (UTI) is a symptomatic bacterial infection of the upper or lower urinary tract caused by organisms of the genus *Proteus* (predominantly *Proteus mirabilis*) occurring in individuals with predisposing factors such as structural or functional urologic abnormalities, indwelling urinary catheters, renal calculi, or host immunocompromise Clinically, affected patients often present with classic dysuria, frequency, flank pain, or fever, carrying an elevate...

Pathophysiologically, *Proteus* species express potent urease enzymes that hydrolyze urea into carbon dioxide and ammonia, resulting in urine alkalinization that promotes the precipitation of magnesium ammonium phosphate and calcium phosphate, directly fostering the formation of struvite (infection) stones, crystal encrustation, and protective biofilms

Clinically, affected patients often present with classic dysuria, frequency, flank pain, or fever, carrying an elevated risk of treatment failure, chronic obstruction, tissue necrosis, recurrent bacteremia, and urosepsis
