For a study, it was determined that renal abscess in children was a rare and severe form of infectious kidney disease that can lead to several dangerous consequences. This report presented a previously healthy 5-year-old girl who developed a renal abscess caused by Escherichia coli (E. coli) generating extended-spectrum- β-lactamase (ESBL), which resulted in bacteremia and renal scarring. The patient arrived at the clinic with a high temperature, headache, vomiting for two days, and a high inflammatory reaction. Researchers identified her with a urinary tract infection and prescribed ampicillin and cefotaxime for therapy. On day 3, they discovered Gram-negative bacilli bacteremia. Her fever remained on day 4, and a computed tomography (CT) scan indicated a left kidney abscess. After identifying the bacteria as ESBL-producing E. coli from the blood culture, they moved to the antibiotic meropenem and continued treatment for 3 weeks. They did not empty the abscess in the kidney. Although they treated renal abscess properly and vanished, successive CT scans revealed a low-density area in the same lesion. A dimercaptosuccinic acid renal scan conducted 4 months after onset suggested renal failure.

Given the rising incidence of ESBL-producing pathogens, doctors should know that community-acquired ESBL-producing organisms might cause kidney abscesses in previously healthy children. Early detection and therapy of a suspected renal abscess are critical for lowering the risk of life-threatening consequences and renal scarring.
