Correlation of maximum urethral closure pressure with Valsalva leak point pressure using air-charged urodynamic catheters.
OBJECTIVE
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.
