Evaluation of residual urine volume after catheterization by ultrasound performed by a nurse

The risk factors described associated with urinary tract infection (UTI) during urethral catheterization are the colonization of the urinary tissue during evaluation. The incidence of UTI is directly related to the duration of the catheterization, and, after considering this ever-present factor in multivariate analysis, it is the main and most important risk factor for UTI. Thus, a simple noninvasive method for determining the volume of urine in the bladder would be very well received. As such, it is possible for properly trained nursing staff to use ultrasound as a vehicle for the evaluation of residual urinary volume, and Brazilian institutions have the potential to gain much based on surveys already conducted.
