Calculating bladder volume on ultrasound

[jasonroy]

Calculating bladder volume on ultrasound involves measuring the three dimensions of the bladder and applying a specific formula. The most commonly used formula is the ellipsoid formula, which assumes the bladder shape approximates an ellipsoid. Here’s a step-by-step guide on how to calculate bladder volume using ultrasound:

Begin by obtaining an ultrasound image of the bladder. Make sure the bladder is adequately distended and that you have a clear view of its borders.

Measure the length (L), width (W), and height (H) of the bladder in centimeters using the ultrasound calipers. These measurements should be taken at the maximum dimensions of the bladder in each plane.
