Urinary volume assessment: comparison of the performance of Mobissom® portable bladder ultrasound equipment with tabletop equipment

This study aimed to compare the performance of Mobissom® portable bladder ultrasound equipment with tabletop ultrasound equipment to assess bladder urine volume. 192 images of 16 adult patients who underwent the exam were analyzed. The bladder volumes obtained by the portable equipment were archived in the form of an image and, later, compared with the ultrasound report of the evaluation performed by a tabletop ultrasound device. The results obtained were compared using the paired t test and the differences were graphically distributed using the Bland & Altmann method. In the overall result, there were no significant differences between the two devices. It is concluded that the equipment, despite the limitation in the visualization of other organs, is easy to use and relevant for bedside assessment.
