We investigated whether lung pressures exerted during forcible exhalation could serve as a surrogate measure for intra-abdominal pressure (PAbd) in patients with SUI or mixed urinary incontinence (MUI). METHODS In this prospective study, female patients with SUI or MUI underwent standard urodynamic evaluation. Minimally invasive measurements of lung-generated pressures (PLung) were also obtained, using Peritron Valsalva Pressure Monitor Mouthpiece (Laborie Medical Tech., VT). PLung and PAbd were recorded at the time of maximum exhalation, and the valsalva leak point pressure (VLPP) was also obtained. Three trials were attempted and then averaged for each patient. Only trials demonstrating leakage per urethra were analyzed. Linear regression modeling was used to correlate PLung with PAbd and VLPP. RESULTS 10 female patients (mean age 50, range 43-66) underwent standard urodynamic evaluation for SUI or MUI (7 and 3, respectively). In these 10 patients, 17 of 30 trials demonstrated leakage per urethra. The Pearson correlation coefficient between mean PLung and mean PAbd was 0.91. Linear regression modeling of mean PLung and mean PAbd, Figure 1, demonstrated a slope parameter of 0.94 (p < 0.001), and the coefficient of determination, R2, was 0.84. Linear regression modeling of mean PLung and VLPP, Figure 2, demonstrated a slope parameter of 1.0 (p < 0.01) and an R2 of 0.70. CONCLUSIONS In our pilot data for patients with SUI and MUI, PLung shows potential for serving as a less invasive surrogate measure for PAbd and VLPP, perhaps eliminating the need for a rectal catheter in urodynamic studies for select patients. Further research is required to validate these findings. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e488 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Harpreet Wadhwa More articles by this author Whitney Halgrimson More articles by this author Francesco Marson More articles by this author William Kobak More articles by this author Ervin Kocjancic More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ..." @default.
