Abstract:
PURPOSE: Numerous studies of the effect of tadalafil on sexual function have been performed. However, its effects on lower urinary tract symptoms (LUTS) are unclear. Therefore, the long-term effects of tadalafil on the improvement of LUTS as well as erectile dysfunction were examined. MATERIALS AND METHODS: 69 patients who visited our hospital reporting LUTS and erectile dysfunction as chief complaints were divided into 3 groups. Group 1 received 10 mg/day alfuzosin (39 patients, age: 61.36+/-8.69), group 2 received 10 mg/day alfuzosin and 5 mg/2 day tadalafil (15 patients, age: 58.00+/-7.91), and group 3 received 5 mg/2day tadalafil (15 patients, age: 54.70+/-10.01). Drugs were administered for 24 weeks. At before and 12 weeks and 24 weeks after drug administration, maximum flow rate, IPSS, quality of life, IIEF-5, and self satisfaction were measured and analyzed. The SPSS 14.0 was used as statistical software, and the data were validated using ANOVA. RESULTS: Between pre- and post-administration, the maximum flow rate significantly increased in all groups (p<0.05). The IPSS of groups 1 and 2 were significantly reduced (p<0.05). Quality of life significantly decreased in group 3 (p<0.05). IIEF-5 for groups 2 and 3 significantly increased (p<0.05). Self satisfaction significantly decreased in groups 2 and 3 (p<0.05). CONCLUSIONS: When alfuzosin and tadalafil were administered together for 24 weeks, both LUTS and erectile dysfunction improved significantly. In the group administered tadalafil alone, LUTS improved. Thus, administration of tadalafil for 24 weeks is able to improve not only erectile dysfunction but also LUTS.
