Summary— Transvaginal linear array ultrasound is described as a method of measuring bladder volumes in the range 2 to 175 ml, overcoming the limitations of abdominal ultrasound at these smaller (though clinically important) volumes. The mean error over the range 10 to 175 ml was 23%. Statistical analysis of preliminary data obtained by this technique shows that bladder volume in ml can be calculated by the formula: Volume = 5.9 × (height × depth) ‐ 14.6 ml (95% confidence limits=±37 ml)
