An outbreak of Pseudomonas aeruginosa infection associated with contaminated urodynamic equipment.

Seven patients developed Pseudomonas aeruginosa urinary tract infections following urodynamic studies, over a two-month period. One patient developed septicaemia and meningitis and died following rupture of a berry aneurysm. Two others required hospital admission for intravenous antibiotic treatment. Pseudomonas aeruginosa was isolated from a pressure dome which covered the pressure transducer of the urodynamic system used for assessing bladder pressure. The device packaging carried the symbol designating this as a 'single use' product, but as an economy measure, a local decision had been taken to change the device monthly.
