VALSALVA LEAK POINT PRESSURE AND BLADDER VOLUME

Twenty-nine females with stress urinary incontinence (SUI) were evalua ted with fluorourodynamics, including Valsalva leak point pressure (VL LP) determinations. VLPP was determined at bladder volumes of 150 mi, 300 mi, and total bladder capacity. The VLPP determinations were analy zed using the signed rank and sign tests. Fluoroscopy was used to anal yze change in type of SUI based on bladder volume. No significant diff erence in VLPP determinations was noted at various bladder volumes. No change in type of SUI was noted at various bladder volumes. We believ e the volume in the bladder does not alter the category of SUI or stat istically change the VLPP determination.
