BladderScan BVI 9400 is a portable 3D ultrasound device that measures bladder volume non-invasively to help assess urinary retention and post-void residual bladder volume. Four published prospective cohort studies (3 full papers, 1 abstract) were identified, involving 239 children and young people in secondary or tertiary care settings. These studies showed heterogeneity in the outcome measures and statistical analyses. The reproducibility and accuracy of the results were also varied. The average cost of a BladderScan BVI 9400 system is between £6000 and £8000, excluding VAT.
