Spinal reflex bladder activity induced by bladder irritation after acute spinal cord transection (SCT) at T9/T10 level. A: cystrometrogram (CMG) during saline infusion demonstrates no reflex bladder contractions after acute SCT, but infusion of 0.25% acetic acid (AA) induces small-amplitude bladder contractions. B: bladder capacity during 0.25% AA infusion is smaller than the saline capacity measured before SCT (n = 10 cats). The downward arrow on the AA CMG trace indicates where the AA bladder capacity is measured. *Significant (P < 0.0001) difference (paired Student's t-test). Note: Bladder capacity (%) was normalized to initial saline control capacity prior to SCT in each cat.
