DId you measure a post void residual? Maybe your measurements were accurate, but you didn’t completely empty your bladder?
Thats very possible, although I suspect it probably had to do with the fact that the bladder is in a more complex geometrical arrangement than a simple formula can 100% estimate. That being said, for me in the emergency department, the ease of this exam/calculation is definitely accurate enough for me to use clinically.
Hey Jacob – nice video. Look forward to working with you more.
