Intravaginal electrical stimulation. Clinical experiments on bladder inhibition.

Abstract

The effect of intravaginal electrical stimulation (IVS) on the bladder in 17 patients with motor detrusor instability was explored. Isotonic volume registrations and cystometries were used for evaluation of volume increase and inhibition of abortive detrusor contractions. With either one or the other method, bladder inhibition was found in all patients, but with both methods only in 6. During isotonic volume registration, the volume increase showed considerable variations ranging between 4 to 465%, and during cystometry between 11 to 3500%. Bladder inhibition proved to be most effective when using a frequency of 10 Hz.
