Urethral and bladder responses to anal electrical stimulation.

Urethral and bladder responses to anal electrical stimulation were evaluated by cystometry and urethral pressure profile measurements in 55 patients with different urethral-bladder dysfunctions. In 50 per cent of the patients examined the electrical stimulation caused normal reciprocal response, that is bladder inhibition with urethral contraction. In other patients the electrical stimulation caused almost all other possible bladder and urethral responses.
