Abstract

Introduction: BPH associated lower urinary symptoms (LUTS) represent one of the most common bothersome condition in day to day urological practice and having negative impact on patient’s quality of life (QoL). Silodosin alone fails to alleviate moderate to severe storage symptoms and thus requiring additional therapeutic approach. The present study was aimed to evaluate the efficacy of Mirabegron addition in BPH patients on silodosin complaining of persistent storage LUTS.


Materials & methods: A total no of 130 patients of BPH on silodosin 8 mg with persistent storage LUTS who had attended urology OPD, Regional Institute of Medical Sciences (RIMS), Imphal were randomized into two groups and prospectively evaluated for 8 weeks. Group-A continued to use silodosin 8 mg only whereas mirabegron 25 mg was added with silodosin in group-B and statistically evaluated.


Results: After completion of 8 weeks group-B showed statistically significant improvement in respect to total IPSS (p-0.04); IPSS storage (p-0.002) and QoL (p- 0.006) score. However no statistically significant difference was noted in term of Q-max and residual urine volume measurement between both the groups.


Conclusion: Mirabegron, a potent B3 adrenoreceptor agonist improves compliance by  relaxation of bladder smooth muscle. Add-on therapy is more effective than monotherapy for improvement of quality of life improvement and alleviation of persistent storage symptoms in BPH patients.
