Leak point pressure does not correlate with incontinence severity or bother in women undergoing surgery for urodynamic stress incontinence.

The aim of this study was to correlate the lowest Valsalva or cough leak point pressure (LPP) with clinical measures of incontinence severity and quality of life in women with pure urodynamic stress incontinence (SUI). This is an analysis of the baseline data from a prospective, multicenter, randomized trial comparing the Monarc transobturator sling to the tension-free vaginal tape. One hundred fifty-five women with SUI underwent urodynamic evaluations including abdominal or vesical LPP determinations, and each completed the Sandvik Incontinence Severity Index, a 3-day voiding diary, and quality-of-life questionnaires. In patients with a LPP, there were no significant correlations between LPP and the above clinical measures of incontinence severity or condition-specific quality-of-life questionnaire scores. In this patient population with pure urodynamic SUI, LPP is not a useful urodynamic predictor of baseline SUI severity and its effects on quality of life.
