Abstract

The bulbocavernosus reflex can be elicited either by penile or urethral stimulation. The mean signal transit time after electrostimulation of the dorsal penile nerve to evoked response in the anal sphincter (35 msec) was only half the signal transit time after stimulation in the posterior urethra (60 msec). Thus, the modified bulbocavernosus reflex elicited either by squeezing the glans penis or by pulling a urethral balloon catheter represents two different reflexes with differenct afferent and probably different intraspinal pathways. In the clinic it is therefore important, when testing the bulbocavernosus reflex, to report how it is elicited.

摘要

球海绵体反射可通过阴茎或尿道刺激引出。电刺激阴茎背神经至肛门括约肌诱发反应后的平均信号传导时间（35毫秒）仅为后尿道刺激后信号传导时间（60毫秒）的一半。因此，通过挤压阴茎头或牵拉尿道球囊导管引出的改良球海绵体反射代表两种不同的反射，其传入神经不同，脊髓内途径可能也不同。因此在临床上，检测球海绵体反射时，报告其引出方式很重要。
