Efficacy of silodosin or mirabegron in medical expulsive therapy for ureteral stones: a prospective, randomized-controlled study.

Silodosin or mirabegron does not improve the stone expulsion rate. Silodosin improves the stone expulsion interval and decreases the need for an analgesic or < 6 mm stones. Mirabegron has no effect on the stone expulsion interval, but decreases the need for an analgesic in patients with distal or sized ≥ 6 mm stones.
