Renal and Urinary Tract Infection

Overview
  • Urinary Tract Infections typically begin from external bacterial seeding of the urethra and extention up the urinary tract. Acute infection of the kidneys, termed acute pyelonephritis, can occur either by upward migration of a urinary tract infection or in rare cases through direct hematogenous seeding of glomeruli. Necrotizing papillitis represents a catastrophic complication of acute pyelonephritis that occurs when renal infection occurs in the context of poor renal perfusion. Additionally, repeated bouts of acute pyelonephritis can evolve into chronic pyelonephritis.
