Urosepsis is a syndrome resulting from a complicated UTI in a patient with one or more of the following signs: tachypnea, tachycardia, hyperthermia or hypothermia, or evidence of inadequate end-organ perfusion.
Inadequate tissue perfusion is often accompanied by elevated plasma lactate, oliguria, or hypoxemia.
Septic shock refers to sepsis syndrome that is accompanied by hypotension. Septic shock is a rare event after urologic procedures. Fortunately, septic shock following urologic procedures (often termed “urosepsis”) has a more favorable prognosis than septic shock from diseases of other organ systems because many urologic disorders are correctable. After correction of underlying urologic factors, the pathophysiology
of urosepsis is often reversible.
