To determine whether real-time ultrasound measurement of multiple linear dimensions of the bladder could be used to estimate total bladder volumes of women in labour. ⋯ It is possible to use real-time ultrasound in estimation of total bladder volumes of women in labour. The implications are that all of those normally selected as being in need of catheterisation could be detected, while about a quarter of those women would avoid unnecessary catheterisation.
