Fig 1.
Different patterns of abdominal pressure (pabd) and detrusor pressure (pdet) during the pressure-flow studies (PFSs).
(A) Patient voids using detrusor pressure with no meaningful abdominal pressure. (B) Patient voids mainly using detrusor pressure but with the addition of abdominal pressure. (C) Patient voids predominantly by abdominal pressure (abdominal straining). EMG = electromylography, pves = vesical pressure.
