Ureteric Stone-Related <i>Escherichia coli</i> Bacteraemia Associated with Spondylodiscitis

Abstract

Escherichia coli (E. coli)-related urosepsis associated with a ureteric stone has been shown to cause a systemic bacteraemia that can spread to other parts of the body. Hematogenous spread of infection is the most common cause of pyogenic spondylodiscitis. A 74-year-old female presented with acute left-sided flank pain and was found to have an obstructing 9 mm distal ureteric stone. After initial management involving ureteric stent insertion, the patient deteriorated and developed an E. coli associated bacteraemia, which proved difficult to treat. Further investigations revealed a subsequent spondylodiscitis, which required a 6-week course of antibiotics and no additional intervention. This case presents the likely association of stone-related bacteraemia, complicated by urinary tract instrumentation leading to spondylodiscitis, and demonstrates the importance of clinicians’ awareness of other causes of unresolving sepsis in an elderly patient.
