Purpose: Typically in Korea, for a standard dose (0.4 mg) of tamsulosin, two low doses (0.2 mg) are administered. The aim of this study was to evaluate and compare the efficacy of tamsulosin (0.2 mg and 0.4 mg) and alfuzosin (10 mg) in the treatment of lower ureteral stones.
Materials and Methods: A total of 141 patients presenting with a single 4- to 10-mm sized lower ureteral stone were randomly assigned to 4 groups. Patients in group 1 (n=41) and group 2 (n=30) received an oral dose of 0.2 mg tamsulosin once and twice daily, respectively, and patients in group 3 (n=36) received a daily oral dose of 10 mg alfuzosin. Patients in group 4 (n=34) received trospium chloride only. The spontaneous passage of stones, the stone expulsion time, and adverse effects were evaluated.
Results: There were no significant differences in patient background, including age, sex, BMI, stone size, stone side, and symptom duration. The spontaneous stone passage rate through the ureter was higher and the stone expulsion time was faster in groups 1, 2, and 3 than in group 4. There were no statistically different changes in groups 1, 2, and 3. The adverse effects observed in all groups were comparable and were mild.
Conclusions: Tamsulosin at 0.2 mg and 0.4 mg and alfuzosin (10 mg) proved to be safe and effective. A first cycle of medical expulsive therapy with tamsulosin 0.2 mg could be considered as an option in the management of single lower ureteral stone.
