Renal abscess due to Pseudomonas aeruginosa: report of two cases.

We report two cases of renal abscess due to Pseudomonas aeruginosa in previously healthy children. The first patient was a nine-year old girl with a three-week history of intermittent fever and the second was a three-year old boy with a four-day history of fever. Pseudomonas aeruginosa was isolated from the urine cultures of both children. In both cases ultrasound and CT/MRI scans revealed the formation of a renal abscess. The patients were successfully treated with administration of antipseudomonal drugs for seven and five weeks, respectively. In both children no surgical intervention was required and the follow-up revealed no impact on the overall renal function or arterial pressure.
