Histopathology of Kidneys in Bacterial UTI Cases

Introduction: Urinary tract infections (UTIs) frequently involve kidneys, causing structural and functional changes.

Epidemiology: UTIs are prevalent worldwide, with higher incidence in women, elderly, and patients with comorbidities.

Bacterial Etiology: Escherichia coli, Klebsiella, Proteus, and other bacteria are the main causative agents of renal infections.

Pathophysiology: Bacterial invasion leads to inflammation, tubular damage, and interstitial alterations in kidney tissue.

Clinical Features: Patients often present with fever, flank pain, dysuria, hematuria, and urinary frequency.

Histopathological Techniques: Kidney tissue is examined using biopsy, H&E staining, and special stains to detect structural changes.

Histopathological Findings: Acute changes include neutrophilic infiltration and tubular necrosis; chronic changes show fibrosis and glomerulosclerosis.

Discussion: Histopathology helps correlate bacterial species, severity of infection, and clinical outcomes.

Conclusion: Kidney tissue evaluation is crucial for diagnosis, management, and prognosis of bacterial UTIs.
