Fig. 2 Detrusor pressure and estimated bladder volume in patient 1. The detrusor pressure and estimated bladder volume are shown at each point in time. During the control session (without stimulation), a detrusor contraction occurred that resulted in leakage (A). Bilateral stimulation of the posterior tibial nerve with either needle (B) or surface (C) electrodes was unable to suppress a detrusor contraction, and leakage occurred during contraction. The amplitude and shape of the time/pressure curve were similar in all three fillings, but each successive filling resulted in increased volume at first contraction.

Fig. 3 Detrusor pressure as a function of time from the second filling in which stimulation was applied with needle electrodes in eight patients. The arrows indicate the onset of leakage, and the bars beneath each tracing indicate that stimulation was applied.
