INHERENT PHYSIOLOGIC MECHANISM CAUSING NEGATIVE DETRUSOR PRESSURE DURING COUGH PROVOCATION IN URODYNAMIC STUDY OBSERVED BY SIMULTANEOUS DUAL CHANNELS OF EMG

초록

Concluding message This dismatched contraction between rectus and perineal muscles, especially an ahead contraction of perineal muscles could cause the negative detrusor pressure during cough provocation of urodynamic study. Thus, our study suggest that this negative pressure during urodynamic study is inherent physiologic reaction, not an artefact.
