[Microbiological evaluation of cystoscope reprocessing at Brest university hospital from January 2007 through December 2014].

PURPOSE: Flexible cystoscopes are high temperature sensitive devices that must undergo high-level disinfection according to Spaulding classification. The objective of this study is to provide epidemiological data on the monitoring of microbiological quality of cystoscopes used in a teaching hospital, in order to determine the compliance rate of disinfection and to describe the main identified microorganisms.

MATERIAL: Prospective study of all the results of microbiological samples taken for 8 years at the Brest teaching hospital. The analysis results were interpreted according to the ministerial recommendations.

RESULTS: During the study, 87 microbiological tests were performed. The rate of non-compliant samples was 19.5% (17/87). This rate reached 24.5% (12/49) of the programmed controls. The microorganisms identified were present in small amounts, corresponding mainly to bacteria from the environment.

CONCLUSION: The rate of non-compliance of the microbiological tests performed on cystoscopes is relatively high (19.5%), but the infectious risk seems limited. Hidden microorganisms are present in small quantities and identified germs are not known to be responsible for urinary tract infections. Educating professionals responsible for cystoscopes reprocessing and conducting regular audits may help to ensure a good level of cystoscope disinfection.
