title: Clinical features of community-acquired Pseudomonas aeruginosa urinary tract infections in children.
abstract: This retrospective chart review sought to determine clinical, radiological, and gender-associated characteristics of community-acquired Pseudomonas aeruginosa (PA) urinary tract infections (UTIs) among children admitted to two medical centers. The records of 73 children with community-acquired PA UTIs were compared with records of 109 children with community-acquired UTIs caused by other pathogens. The mean age of both groups was similar. The PA UTI group included more boys. Features significantly more common in the PA UTI group were the number of patients who had undergone urinary tract surgery, patients with skeletal and/or neurological malformation, patients with >1 previous episode of UTI, patients on prophylactic antibiotic treatment on admission, and patients with pathological renal ultrasound and voiding cystourethrography (VCUG) findings. Multivariate logistic regression analysis revealed the following to be associated with PA UTI: >1 episode of UTI in the past [odds ratio (OR) = 35.5; 95% confidence interval (CI) 11.6-108.7], previous urinary tract surgery (OR = 34.1; 95% CI 7.00-166.2), and pathological VCUG results (OR = 2.62; 95% CI 0.96-7.15). In conclusion, PA UTI is associated with >1 previous UTI, urinary tract abnormalities, and past urinary tract surgery. We recommend that when UTI is suspected in children with these risk factors, a thorough radiologic investigation, including a VCUG, should be considered.
