Abstract:
PURPOSE: To determine the correlation between the maximal urethral closure pressure and the stress leak-point pressure in the patients with genuine stress incontinence, and to define the benefit of maximal urethral closure pressure for detecting type III stress urinary incontinence. MATERIALS AND METHODS: 115 patients with genuine stress incontinence were evaluated with multichannel urodynamics. Maximal urethral closure pressures and stress leak-point pressures were determined and correlated. RESULTS: There was a statistically significant relationship (p=0.0001) between the stress leak-point pressure and the maximal urethral closure pressure. However, a correlation coefficient of 0.50 demonstrated poor clinical relationship. A stress leak-point pressure less than 60 centimeter H2O had 91.7% sensitivity, 78.8% specificity and 28.9% positive predictive value in detecting low-pressure urethra. CONCLUSION: The stress leak-point pressure has poor clinical correlation to the maximal urethral closure pressure. And maximal urethral closure pressure has no additional benefit for detecting type III stress urinary incontinence.
