title: International Prostate Symptom Score for assessing lower urinary tract dysfunction in women.
abstract: OBJECTIVE
  Some lower urinary tract dysfunction (LUTD) subtypes may have similar symptoms. This study aimed to investigate the feasibility of using the International Prostate Symptom Score (IPSS) to evaluate lower urinary tract symptoms (LUTS) in women.
  
  
  METHODS
  All consecutive women with non-stress urinary incontinence LUTS who visited the urologic clinics for treatment were prospectively enrolled. LUTS include urinary storage, voiding, and post-micturition symptoms. All enrolled patients were requested to complete the Overactive Bladder Symptom Score (OABSS) and the modified Indevus Urgency Severity Scale (IUSS) questionnaires as well undergo uroflowmetry and post-void residual testing. A videourodynamic study was also performed, if indicated, for LUTD.
  
  
  RESULTS
  A total of 222 women were enrolled, including 60 with overactive bladder (OAB) dry, 42 with OAB wet, 78 with bladder oversensitivity, and 42 with voiding dysfunction. A significantly higher IPSS voiding to storage subscore ratio (IPSS-V/S) and IPSS voiding score were found in the voiding dysfunction group. IPSS-V/S was found to have the highest area under the receiver-operating characteristic curve for predicting voiding LUTD than other noninvasive methods, and an IPSS-V/S of ≥1.33 had the best predictive value for female voiding LUTD with a high negative predictive value (97.4 %). In addition, significantly higher IPSS storage subscore (IPSS-S) values were found in the OAB wet subgroup, and the IPSS-S was well correlated with the OABSS and IUSS.
  
  
  CONCLUSIONS
  The IPSS can be used to evaluate female LUTD. IPSS-V/S may provide an initial guide for the treatment of voiding dysfunction in women. In addition, IPSS-S may be used for evaluating storage LUTD in women.
