It is normally controlled with anti-muscarinic medication or intra-detrusor botulinum toxin injections, which can have side effects. Neuromodulation of the pudendal nerve has been shown to increase bladder capacity and reduce pressures. We have investigated the effectiveness of an investigational wearable dorsal genital nerve stimulation (DGNS) device in controlling NDO in people with SCI over an 8 week period. METHODS: People with urodynamically proven NDO following SCI were invited to participate and gave informed consent. Baseline bladder diaries and questionnaires were completed. Urodynamics were performed with 4 filling cycles: a control, with DGNS initiated by investigator when pressure exceeded 10 cmH2O, with DGNS initiated by participant based on sensation and a final control. Maximum cystometric capacity (MCC) and maximum detrusor pressure (MDP) were recorded. DGNS was applied through a novel wearable device with cathode located on dorsum of penis or adjacent to clitoris and anode placed on thigh. DGNS was applied at 20 pps, 200 mcs pulse width and minimum current based on threshold for pudendo-anal reflex. Participants used the device at home for an 8 week period and then returned for further urodynamics cycles. A final set of urodynamics was conducted 4 weeks post-intervention. RESULTS: 11 participants with SCI were recruited (average age 48.4 years (range 26-65) and average time since injury 9 years (range 1-29). At baseline visit, control MCC was 201±139 ml which was significantly increased to 373±136 ml with DGNS (n=11). 5 participants have completed the full trial; MCC and MDP during control (solid line) and DGNS (dashed line) fills at each visit are shown in Figure 1. Control MCC was increased after 8 weeks, but this returned to baseline after intervention. CONCLUSIONS: We have demonstrated that DGNS through an investigational wearable device can increase bladder capacity and reduce MDP and provide an alternative to management of NDO following SCI.
