The accuracy of Bardscan: a new tool for the measurement of the bladder volume.

The Bardscan has been recently introduced into clinical practice with the potential advantage of providing real time ultrasound imaging and hence the ability for an accurate estimation of bladder volume, and concurrently the detection of any incidental bladder pathology. Independent clinical data regarding this machine is limited, and therefore this study was carried out to ascertain whether the Bardscan machine is accurate in the estimation of bladder volume for women in the urodynamic clinic and in the postoperative period. Fifty four women had a Bardscan estimation of their bladder volume which was compared with an immediately obtained catheter volume. The results show that the Bardscan volumes correlate closely with the bladder volumes detected on catheterization (r =0.982, p=0.16). This study has shown that the Bardscan is an accurate tool in the measurement of bladder volume in women with the advantages of being safe, non-invasive and well tolerated by patients. The aim of this study was to evaluate the accuracy of the Bardscan machine in the measurement of urinary bladder volume.
