To evaluate the activity of the therapeutic agents (tamsulosin and/or tolterodine) used to accelerate the expulsion of stones and to reduce the probable complications during observation of the medical treatment of distal ureteral stones to allow spontaneous passage.


A total of 120 patients with distal ureteral stones were included in the study. Patients with stones less than 10 mm and allowing urinary flow were included in the study. The patients were studied in four randomly divided groups. Group 1 patients received tamsulosin 0.4 mg/day, group 2 patients received tamsulosin 0.4 mg/day plus tolterodine 2 mg (twice a day), group 3 patients received tolterodine 2 mg (twice a day), and group 4 patients did not receive any medical treatment (control group).


Differences among the four groups in patient age and stone dimension were not statistically significant (P >0.05). The stone expulsion rates were greater (P <0.05) in groups 1 and 2 than in groups 3 and 4. A significant variation (P <0.05) regarding the time to stone expulsion was observed in groups 1 and 2.


In our study, the use of tamsulosin for the expulsion of distal ureteral stones was effective; however, the use of tolterodine provided no additional advantages.
