Abstract
A portable ultrasound unit (BladderScan BVI 2000) has been developed which offers a non-invasive procedure to determine urine volume. This study was undertaken to evaluate the accuracy of measurements by this method. A high correlation was demonstrated between the catheterized volume and ultrasound estimation (r=0.98, p<0.0001). In patients with residual urine of >50 ml, the unit could correctly identify 93%. This instrument is useful in estimating the residual urine volume, and its application is recommended as an alternative to catheterization for the determination of residual urine.
