Normalized tissue impedance of the urinary bladder U(t)/U(0) and cystomanometry p(t)/p(0) as a function of time during direct nerve stimulation with 15 mA, 1000 µs pulse width and 30 Hz on the vesicouterine ligament according to the depicted stimulation protocol. Impedance measurement was carried out with four needle electrodes (setup 2). Tissue impedance of the bladder and bladder pressure are consistent and rise during direct nerve stimulation and decrease during relaxation.
