Reproducibility of Leak Point Pressure in Female Stress Urinary Incontinence

To assess the reproducibility of the Valsalva leak point pressure (VLPP) based on urodynamics in females with stress urinary incontinence (SUI).
From October 2008 to December 2009, 65 consecutive women with urodynamically confirmed SUI underwent duplicate VLPP measurements. The intra-individual reproducibility of the VLPP recording obtained by one urologist was determined. The two observations were separated by a 10-min interval.
The differences between the repeated measurements were not significant (initial vs. repeat VLPP, 84.8 ± 19.9 vs. 86.7 ± 20.3 cmH2O; P = .094). Repeated VLPP measurements were reproducible. Defining intrinsic sphincter deficiency (ISD) as VLPP In female SUI, the VLPP is a reproducible method for evaluating urethral resistance. For VLPP
