[Effectiveness of cleaning or disinfecting the urinary meatus before urinary catheterization: a systematic review].

The urinary tract infections associated with catheterization are very common in hospital and home care contexts. Currently there are several recommendations for its prevention, however, when approaching the kind of solute used in the urinary meatus prior to catheterization doubts continue to persist. Thus this study aimed at determining the effectiveness of cleaning the urinary meatus with water or saline comparing to its sterilization through a systematic review and meta-analysis. In order to do so, the principles proposed by the Cochrane Handbook were followed, a critical analysis was conducted by two researchers and the statistical analysis was performed with the use of STATA 11.1. We concluded that the cleaning or disinfection of the urinary canal prior to bladder catheterization is not statistically significant (OR=1.07, CI 95%=0.68-1.68, p=0.779) and that there is some evidence that the use of water/saline reduces rates of UTI (urinary tract infection).
