Bladder inhibition by electrical stimulation of the perianal skin

Abstract

Transcutaneous electrical stimulation was applied to the perianal skin of 25 patients with frequency, urgency or incontinence. Repeated cystometrogram during this stimulation disclosed suppression of detrusor activity, inhibition of detrusor instability in 4 of 8 patients and increase of maximum cystometric capacity in 5 of 25 patients. Electromyographic activity of the anal sphincter muscle increased in all the 25 patients. Poststimulation improvement was observed clinically in 9 of 12 patients.
