Purpose:
To assess the reproducibility of the Valsalva leak point pressure (VLPP) based on urodynamics in females with stress urinary incontinence (SUI).
Materials And Methods:
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.
Results:
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 < 60 cmH2O, the diagnosis of ISD changed between successive tests in three cases (from 55 to 89, 58 to 64, and 61 to 55 cmH2O).
Conclusion:
In female SUI, the VLPP is a reproducible method for evaluating urethral resistance. For VLPP < 90 cmH2O, the diagnosis of ISD changed in repeated measurements in some patients; therefore, other clinical findings must be considered when deciding on a treatment method.
