Example cystometrogram trials in cats during distention evoked voiding (A–C) and voiding with unilateral DPeriN phasic stimulation (D–F). (A) Bladder pressure (top) and voided volume (bottom) during a distention evoked trial. (B) An expanded trace from (A) showing bladder pressure (top) and voided volume during the bladder contraction. (C) An expanded view of the bladder pressure demonstrating the absence of high frequency oscillations (HFOs) during a void event. (D) Bladder pressure (top) and voided volume (bottom) during DPeriN phasic stimulation (red trace). DPeriN stimulation is turned on during a voiding event and is subsequently turned off after the end of the void. (E) An expanded trace from (D) showing bladder pressure (top) and voided volume during the bladder contraction. DPeriN phasic stimulation (red trace) elicited HFO’s during stimulation. (F) An expanded view of the bladder pressure during phasic stimulation. Oscillations in bladder pressure follow each stimulation burst. G) Example of urethral pressure in response to 2 Hz bursts of DPeriN stimulation. Urethral pressure recorded during bladder empty conditions. The inter-pulse frequency was 40 Hz, and each burst was 100 ms in duration.
