A series of 23 women patients attending a urodynamic clinic were recruited for a study. After successful voiding of the bladder, sterile water was introduced in additions of 10, 15, and then 25 ml increments up to a final cumulative total of 175 ml. At each volume a measure of height (H) in mm and depth (D) in mm of largest ultrasound bladder images were taken. The product H <U+00D7> D was taken as a measure of liquid volume.
