Abstract

Purpose: The valsalva leak point pressure (VLPP), a quantitative measure of sphincteric function, is used widely to diagnose intrinsic sphincteric deficiency. The purpose of this study was to evaluate the correlation between VLPP and maximum urethral closure pressure (MUCP) in patients with stress urinary incontinence.
Materials and Methods: Two hundred sixty two women with stress urinary incontinence were evaluated prospectively, comparing VLPP with MUCP to evaluate their correlation.
Results: There was a statistically significant relationship between VLPP and MUCP (p=0.0001), however a correlation coefficient of 0.29 demonstrated poor clinical relationship.
Conclusions: The VLPP is a simple and reproducible methods for evaluating urethral resistance in stress urinary incontinence. The MUCP has statistically significant relationship with VLPP, however it is not clinically useful to evaluate urethral sphincter function because women with normal or high MUCP had leakage at low VLPP and vice versa.
