This study examined test-retest reliability of four patient-reported outcome measures for patients with overactive bladder (OAB): Overactive Bladder Questionnaire (OAB-q), Patient Perception of Bladder Condition (PPBC), Urgency Questionnaire (UQ), and Primary OAB Symptom Questionnaire (POSQ). ⋯ The OAB-q, POSQ, and UQ demonstrated good test-retest reliability, with ICCs roughly equivalent or superior to those previously reported for 7-day micturition diaries. Findings suggest that the four measures examined in this study demonstrate the necessary reproducibility for use as outcome measures for OAB treatments.

Pudendal nerve stimulation has beneficial effects on numerous pelvic floor function impairments such as urinary and/or fecal incontinence, retention, and constipation. In preceding literature the implant technique required a fairly complex and invasive surgery, although recent advances with percutaneous placement of the lead through an introducer have made the procedure much less invasive. We performed staged procedure similar to that of sacral neuromodulation (SNM) to place tined lead near the pudendal nerve, using neurophysiological guidance that allowed accurate pudendal nerve stimulation through either perineal or posterior approach. We have named this approach chronic pudendal nerve stimulation (CPNS). ⋯ Chronic pundedal nerve stimulation is feasible. Neurophysiological guidance is mandatory to place the lead near the pudendal nerve either using perineal or posterior approach. Further studies must be carried out to identify the best stimulation parameters and to verify the long term results.
