Figure 1.

Example of poststimulus voiding using a Brindley stimulator. The three upper traces show the intravesical (Pves), intra-abdominal (Pabd), and detrusor (Pdet) pressures during stimulation with a Brindley stimulator. The increase in EMG signal reflects the activation of the stimulus during 5 seconds. Stimulation is activated every 12 seconds. The intermittent stimulation pattern allows the urethral sphincter to relax while the detrusor pressure remains elevated. This results in an intermittent flow pattern.
