Abstract

Purpose: 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.
