title: Diagnostic Tool for Assessing Overactive Bladder Symptoms: Could the International Prostate Symptom Storage Subscore Replace the Overactive Bladder Symptom Score?
abstract: OBJECTIVE
  The goal of this study was to compare the International Prostate Symptom Storage Subscore (IPSS-s) and the overactive bladder symptom score (OABSS) as tools for assessing the symptoms of overactive bladder (OAB).
  
  
  METHODS
  A cross-sectional study was conducted of a sample of 1,341 patients aged 50 years and older with lower urinary tract complaints who had undergone a medical examination at one of several centers. For each patient, we reviewed the International Prostate Symptom Score and the OABSS. The patients were divided into 2 groups according to their IPSS-s result (group 1, score ≥6; group 2, score<6) and into another 2 groups according to their OABSS diagnosis (group 3, OAB patients; group 4, non-OAB patients). We determined whether the OABSS varied to a statistically significant extent between groups 1 and 2. Furthermore, we evaluated the correlation of IPSS-s severity with the OABSS results in group 3, and the OAB diagnosis rate was compared between groups 1 and 2.
  
  
  RESULTS
  In groups 1 and 2, the OABSS results were not found to vary to a statistically significant extent (P=0.326). In group 3, no significant correlation was found between IPSS-s severity and the OABSS results (P=0.385). In the prevalence analysis, no statistically significant difference was found among the groups, and the receiver operating characteristic curve showed an area under the curve of 0.474.
  
  
  CONCLUSIONS
  The results of this cross-sectional analysis suggest that the IPSS-s and the OABSS are not significantly correlated. Although both scores are used to measure OAB symptoms, the simultaneous use of IPSS-s and OABSS is not warranted.
