The impact of adding solifenacin to tamsulosin therapy for treatment of storage lower urinary tract symptoms owing to benign prostatic hyperplasia

Background Benign prostatic hyperplasia (BPH) is a common problem in aging males which has a potential impact on patients' health-related quality of life. In the present prospective study, we evaluated the effect of adding solifenacin to tamsulosin, compared to tamsulosin alone on overactive bladder symptoms scores (OABSS) and patients' quality of life (QoL) in patients with filling lower urinary tract symptoms due to BPH. Methods Patients included in our study were randomly assigned into 2 groups: group 1 included patients with BPH who received tamsulosin alone and group 2 included patients with BPH who received a combination of tamsulosin and sofinacin. Treatment period was 12 weeks in both groups. Quality of life and overactive bladder symptoms score questionnaires were obtained and compared in both groups before and after treatment. Results No significant differences were found between both groups before treatment. At the end of treatment period, The QoL score for Group 1 patients was significantly greater than the other group (mean rank was 138.98 in tamsulosin group versus 62.02 in the combination group, P-value < 0.01). Similarly, OABSS for tamsulosin only group was significantly higher than combined treatment patients (mean rank was 145.03 in tamsulin group versus 55.98 in the combination group, P-value < 0.01). Conclusion Adding solifenacin to tamsulosin was associated with an improvement of QoL and OABSS in patients with irritative urinary symptoms due to BPH when compared with tamsulosin monotherapy.
