Fig. 2From: Tarlov cyst with self-healing cauda equina syndrome following combined spinal-epidural anesthesia: a case reportUrodynamic testingWith the increase of bladder perfusion, intravesical pressure was maintained at an inadequate level lower than 31 cmH2O, even when abdominal pressure was applied. Bladder perfusion was 106 ml at First Sensation and 423 ml at First Desire and 491 ml at Strong Desire. Uroflowmetry and viod volume were not able to be measured. (A) Pves: Intravesical pressure (normal range: 31–42 cmH2O). (B) Pabd: Abdominal pressure. (C) Pdet: Detrusor pressure. Pdet = Pves - Pabd (D) Flow: Uroflowmetry. (E) Volume: Viod volume. (F) VH2O: Bladder perfusionBack to article page
