Abstract
Introduction and hypothesis
Overactive bladder (OAB) is a syndrome with symptoms such as urinary frequency, urinary urgency and urge incontinence. The aim of this study is to assess the validity and reliability of the Turkish overactive bladder symptom score (OABSS) and to evaluate the results of mirabegron treatment with OABSS.
Methods
The study was carried out with 117 patients who applied to the urology outpatient clinic between June 2018–January 2019. OABSS Turkish validation was developed from the English version. Demographic data of the patients were recorded. The OABSS, overactive bladder questionnaire (OAB-v8) and International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) were filled out by the patients. The patients were asked to fill in these questionnaires after 2 weeks. Patients receiving mirabegon treatment were evaluated with the same questionnaires and bladder diaries after 8 weeks.
Results
A total of 117 OAB patients, including 82 OAB-wet and 35-OAB dry, were included in the study. The mean age of the patients was 46.79 ± 14.26 (18–78) years, and the mean duration of OAB complaint was 32.28 ± 32.21 months. The mean score of the OABSS is 9.9 ± 3.14. The results of the reliability assessment showed that the intraclass correlation coefficient of the total OABSS score was 0.71 (weighted coefficients of individual item points, 0.635–0.831), and the Cronbach α was 0.736. In the validity analysis, the OABSS total score was highly correlated with that belonging to other questionnaire forms (OAB-v8, ICIQ-SF and bladder diary). After the treatment with mirabegron, mean OABSS scores of the patients improved significantly from baseline to the 8th week (p < 0.001).
Conclusion
The Turkish version of the OABSS has been approved as a valid and reliable tool for evaluating OAB. Mirabegron used daily improved the symptoms of OAB in patients.
