Effects of ejaculation by penile vibratory stimulation on bladder capacity in men with spinal cord lesions.

ABSTRACTPurpose: We examined the effects of ejaculation by penile vibratory stimulation on bladder capacity in men with spinal cord lesions.Material and Methods: Included in our study were 14 men with spinal cord lesions from C4 to T7 with detrusor hyperreflexia. Cystometry was performed before and immediately after ejaculation by penile vibratory stimulation to establish baseline conditions and repeated after 1 month of ejaculation by penile vibratory stimulation every third day. The third cystometry study was done after 1 month of ejaculation by penile vibratory stimulation every third day at home to determine any long-term effects of treatment. This third cystometry was performed 72 hours after the last ejaculation to exclude any acute effects of ejaculation by penile vibratory stimulation on detrusor hyperreflexia. In addition, 1 to 3 days later ejaculation was induced by penile vibratory stimulation and immediately followed by cystometry to examine whether it was possible to achieve an acute effect a...
