Objective: The objective of this study was to evaluate the safety and efficacy of tamsulosin hydrochloride 0.2 mg (TAM) and its combination with solifenacin succinate 5 mg (SOL) after transurethral resection of the prostate (TURP).
Patients and methods: The patients were randomized into three groups: TURP (group 1), TURP plus TAM (group 2), and TURP plus TAM + SOL (group 3). Patients in group 2 and group 3 received medication for 4 weeks. The primary efficacy end points were the mean change in total International Prostate Symptom Score (IPSS) and IPSS subscores. The secondary end points included quality-of-life score, Overactive Bladder Symptom Score, and short-form voiding and storage score of International Continence Society.
Results: In total, 37 men (31.8%) in group 1, 37 men (31.8%) in group 2, and 42 men (36.2%) in group 3 completed the study. In total IPSS, no significant improvement was seen from baseline to the end of treatment in groups 2 and 3 compared with group 1. However, in group 2, the decrement in the IPSS storage score was smaller than group 1 (P=0.02), and in group 3, the decrement in the IPSS voiding score was smaller than group 1 (P=0.05). In groups 2 and 3 compared with group 1, improvements in the quality of life score, total score of Overactive Bladder Symptom Score, and short-form voiding score and storage score of International Continence Society were not statistically significant.
Conclusion: Treatment with TAM and combination of TAM and SOL did not have significant additional benefits for lower urinary tract symptoms during the early recovery period after TURP.
