Is the leak point pressure alone an accurate indicator of intrinsic sphincteric deficiency?
The aim of this study was to determine the characteristics of women who meet the criteria for intrinsic sphincteric deficiency (ISD) on maximum urethral closure pressure (MUCP) but not on leak point pressure (LPP) measurement. We performed a cross-sectional chart review of every patient who underwent multichannel, microtransducer urodynamic testing in our center between 1994 and 1996 (n=423). From this population we culled a sub-population of women who fit into one of the following two groups: women with no evidence of ISD on MUCP or LPP and women with evidence of ISD on MUCP only. Logistic regression was used to identify independent predictors of group membership. Increasing age (>60.5 years) and a positive supine empty stress test were the only independent predictors of membership in the group of women with ISD on MUCP only. Knowledge of these risk factors may help clinicians in choosing appropriate pre-operative testing.
