Urinary incontinence during orgasm.

Urinary incontinence occurring during orgasm in women is an infrequently volunteered symptom. We studied 3 such patients to understand the mechanism behind such leakage. Urodynamic studies were performed prior to and during orgasm. It was found that during orgasm, there was involuntary bladder contraction with simultaneous urethral relaxation, resulting in leakage. Similar studies performed prior to orgasm did not reveal any involuntary bladder contraction. We believe that incontinence during orgasm is multifactorial: the most important causes are sphincter incompetence, neuropathic hyperreflexic bladder, and non-neuropathic idiopathic bladder instability.
