Efficacy of Propiverine in Improving Symptoms and Quality of Life in Female Patients with Wet Overactive Bladder

Objectives: The present prospective study was conducted to assess the effects of propiverine hydrochloride in improving symptoms and quality of life (QoL) in female patients with wet OAB. Methods: Propiverine was administered orally for 8 weeks to 58 female patients who had urgency incontinence. Prior to administration, and at 4 and 8 weeks after administration, symptoms and QoL of the patients were assessed using a micturition diary, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and the King's Health Questionnaire (KHQ). In addition, the relationships between changes in frequency of urinary incontinence or amount of urine leakage following treatment and changes in each domain of the KHQ were investigated by multiple regression analysis. Results: After administration of propiverine, the mean numbers of daily micturitions, incontinence episodes, and urgency episodes assessed on the basis of the micturition diary significantly improved in comparison to the baseline: from 11.7 to 9.6 for daily micturitions, from 2.8 to 1.1 for incontinence episodes, and from 5.9 to 2.3 for urgency episodes in 8 weeks. The mean of the ICIQ-SF total scores significantly decreased, from 8.4 to 4.6 points at 4 weeks and to 3.6 points at 8 weeks. The mean scores for three individual items in the ICIQ-SF, namely, frequency of incontinence episodes, amount of leakage, and impact on everyday life also significantly improved. The KHQ scores significantly improved at both 4 and 8 weeks post-administration in all domains except personal relationships. In the multiple regression analysis, improvement in frequency of incontinence was significantly related to the domain of severity measure of the KHQ, while improvement in amount of leakage was significantly related to the domains of general health perception and social limitations. Conclusion: Propiverine hydrochloride contributed to improvements not only in symptoms but also in QoL in female patients with wet OAB.
