[Study of bulbocavernosus reflex using electrostimulation electromyography].
Evoked response of bulbocavernosus reflex was taken in 8 normal control individuals and in 15 abnormal voiding patients (8 benign prostatic hyperplasia, 4 diabetic neuropathy, 3 supranuclear neurogenic bladder). the latency in control group showed 31.5 +/- 5.0 msec duration after penile stimulation and 65.4 +/- 11.0 msec duration after posterior urethral stimulation. The latency in diabetic neuropathy group was obviously prolonged but not that in the supranuclear neurogenic bladder group. This modern neurophysiological electrostimulation method provides simple and accurate information of bulbocavernosus reflex.
