Impact of combined usage of questionnaire forms with bladder diary for overactive bladder syndrome

Bladder diary and questionnaire forms have an important role in the diagnosis of overactive bladder (OAB) syndrome and can predict response to OAB treatment. We aimed to evaluate the correlation between three different validated Turkish OAB questionnaires and bladder diary form.

Patients aged over 18 years who admitted to the urology outpatient clinic with OAB symptoms between March 2019 and April 2020 were enrolled into the study. Demographic data of the patients were recorded, and they were asked to complete a 3-days bladder diary. In addition, the patients filled Turkish validated OAB version-8 (OABv8), the International Consultation of Incontinence Questionnaire-Short Form (ICIQ-SF), and OAB Symptom Score (OABSS) questionnaire. The relationship between these questionnaire forms and bladder diary was evaluated with statistical analysis. The significant p was p < 0.05.

A total of 592 patients were included in the study. The mean total points of the questionnaire forms were 22.07 ± 8.34 (0-38) for OABv8, 10.78 ± 7.21 (0-21) for ICIQ-SF, and 9.36 ± 3.53 (0-15) for OABSS, respectively. There was a positive poor correlation between OABv8 questionnaire form and nocturia (r = 0.287, p = 0.013). There was a positive moderate correlation between OABSS and the number of micturition (r = 0.405, p = 0.03) and nocturia (r = 0.508, p = 0.036), and the urgency incontinence was negatively moderate correlations (r = -0.525, p = 0.041).

Both questionnaire forms and bladder diaries are important in the evaluation of OAB patients. According to our results the bladder diary and OABSS questionnaire forms were interrelated.
