title: Reproducibility of Leak Point Pressure in Female Stress Urinary Incontinence.
abstract: OBJECTIVE
  To assess the reproducibility of the Valsalva leak point pressure (VLPP) based on urodynamics in females with stress urinary incontinence (SUI).
  
  
  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 &plusmn; 19.9 vs. 86.7 &plusmn; 20.3 cmH2O; P = .094). Repeated VLPP measurements were reproducible. Defining intrinsic sphincter deficiency (ISD) as VLPP &lt; 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).
  
  
  CONCLUSIONS
  In female SUI, the VLPP is a reproducible method for evaluating urethral resistance. For VLPP &lt; 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.
