  "abstract": "Introduction\n\nKlebsiella pneumoniae is broadly classified into classical and hypervirulent pathotypes, with the latter associated with invasive infections and hematogenous dissemination.Case presentation\n\nAn 89-year-old woman presented with fever and fatigue. Imaging revealed a large retroperitoneal abscess. Klebsiella pneumoniae was isolated from both pus and urine cultures, and the string test was positive. The clinical response to nonsurgical treatment was poor; however, definitive infection control was achieved after open surgical drainage.Conclusion\n\nThis case highlights serial reassessment and kidney-preserving open drainage for string test-positive infection refractory to percutaneous source control.",
