    Abstract:
    INTRODUCTION AND HYPOTHESIS: The objective of this study was to measure the correlation of maximum urethral closure pressure (MUCP) with Valsalva leak point pressure (VLPP) in women with urodynamic stress incontinence using air-charged urodynamic catheters. METHODS: Records of all women who underwent urodynamic testing for urinary incontinence using air-charged catheters over a 3-year period were reviewed. Data included scores on the Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). RESULTS: One hundred ninety-three women met the criteria for urodynamic stress incontinence. There was a modest correlation of MUCP with VLPP at 200 mL (r = 0.46, p < 0.001) and a low correlation of MUCP with VLPP at maximum capacity (r = 0.35, p < 0.001). There was no correlation of UDI-6 or IIQ-7 scores with MUCP or VLPP. CONCLUSIONS: The low to modest correlation of VLPP with MUCP with air-charged catheters is similar to what has been reported with water-filled and microtransducer catheters.
