Proteus pyelonephritis

Proteus pyelonephritis is an upper urinary tract infection characterized by bacterial inflammation of the renal parenchyma and renal pelvis caused by species of the Gram-negative genus *Proteus*, most commonly *Proteus mirabilis* It disproportionately affects elderly individuals, patients with indwelling urinary catheters, and those with structural or functional urinary tract abnormalities

It disproportionately affects elderly individuals, patients with indwelling urinary catheters, and those with structural or functional urinary tract abnormalities This process markedly alkalinizes the urine, causing mucosal damage and precipitating magnesium ammonium phosphate and calcium phosphate crystals, which predisposes patients to struvite staghorn calculi, urinary obstruction, and renal parenchymal scarring

Clinically marked by fever, flank pain, costovertebral angle tenderness, and pyuria, its hallmark pathophysiology involves potent bacterial urease activity that hydrolyzes urea into ammonia and carbon dioxide
