[Evaluation of the empty bladder stress test in supine position as a marker of severity and quality of life in women with stress urinary incontinence].
OBJECTIVE
To assess the association between empty bladder stress test and objective and subjective measures of stress urinary incontinence (SUI) severity.


METHODS
Prospective, analytic and descriptive study of females with diagnosis of stress urinary incontinence referred for urodynamics study. Every patient underwent medical history (including number of daily pads) and physical examination, ISIQ-SF and short IIQ-7 questionnaires, and full urodynamic study, including the measurment of the abdominal leak pressure point (ALPP). Positive empty stress test was defined as stress urine leak on physical exam after uroflowmetry evacuation and in absence of significant post-void residual. To evaluate the relationship between empty bladder stress test and each one of the stress urinary incontinence severity measures, Stundent's t test was performed, considering a 〈0.05 value statistically significant.


RESULTS
107 patients were studied in the final analysis; of them 49 had empty bladder stress test (+) and 58 (-). Patients with positive test wet a greater number of protectors per day (3.9 vs 2.8; p 0.013), higher ICIQSF score (15.04 vs 12.22; p 0.0007), higher IIQ-7 score (52.2 vs 37.5; p 0.0049) and lower urodynamics ALPP (73 cm H2O vs 91 cm H2O; p 0.0002).


CONCLUSIONS
Patients with SUI and positive empty bladder stress test had a strong association with the objective and subjective perception of urine incontinence severity with a negative impact in patients quality of life.
