[Electrostimulation of the urinary bladder].

The authors present their first results with urinary bladder stimulation in dogs by using an electronic stimulator and electrodes of their own construction. Neurostimulation was carried out by means of contactless application of electrical rectangular pulses with the voltage ranging from 1 to 10 volts, frequency from 10 to 300 Hz and pulse with 1 ms. Due to the stimulation of the branches of the pelvis plexus an isolated contraction of the bladder detrussor with an increase of intravesical pressure up to 65 cm H2O was observed with subsequent spontaneous voiding. The stimulation of the intact sacral root S2 led to detrussor-sphincteric dyssynergia caused by simultaneous contraction of the detrussor and the striated urethral sphincter. The poststimulus spurt of urine was observed at the end of each S2 stimulation. The authors inform about the further plan of experimental work before introducing the method into clinical practice.
