Klebsiella pyelonephritis

Klebsiella pyelonephritis is an acute upper urinary tract infection characterized by bacterial invasion and inflammation of the renal parenchyma and pelvicalyceal system caused by *Klebsiella* species, most commonly *Klebsiella pneumoniae* It predominantly arises from bacteria ascending from the lower urinary tract, frequently affecting hospitalized patients, older adults, individuals with indwelling urinary catheters, and those with underlying conditions like diabetes mellitus or structural uro...

Klebsiella pyelonephritis is an acute upper urinary tract infection characterized by bacterial invasion and inflammation of the renal parenchyma and pelvicalyceal system caused by *Klebsiella* species, most commonly *Klebsiella pneumoniae* Pathophysiologically, the organism's thick polysaccharide capsule and virulence factors promote tissue adherence and evasive inflammatory responses, which can lead to severe complications such as renal abscess formation, emphysematous pyelonephritis, bacteremi...

It predominantly arises from bacteria ascending from the lower urinary tract, frequently affecting hospitalized patients, older adults, individuals with indwelling urinary catheters, and those with underlying conditions like diabetes mellitus or structural urologic abnormalities Defining clinical features include high fever, flank pain, costovertebral angle tenderness, nausea, and pyuria, accompanied by laboratory confirmation of the pathogen in urine or blood cultures

Defining clinical features include high fever, flank pain, costovertebral angle tenderness, nausea, and pyuria, accompanied by laboratory confirmation of the pathogen in urine or blood cultures
