Abstract

The bulbocavernosus reflex (BCR) was evaluated before, during and after micturition in 35 patients. All the 19 patients with upper motor neuron lesions had a positive BCR during micturition. By comparison, 11/16 of the patients with a lower motor neuron lesion or with urogynecologic diseases did not have a BCR during micturition. The persistence of BCR during voiding seems to be a loss of central inhibition and maybe represent a good sign of upper motor neuron bladder dysfunction.
