Mirabegron vs. solifenacin in control of endoscopically inserted ureteral stent-related symptoms.

Abstract

We aimed to assess the efficacy and safety of Mirabegron vs. solifenacin to treat LUTS resulting from DJ-stent insertion. A total of 97 patients who had DJ-stent inserted for urinary stone disease were randomly divided into three groups according to received treatment. Group A took Mirabegron 50mg daily, group B took solifenacin 5mg daily from the 4th day after stent placement until the stent was removed, and group C only was hydrated well. All patients were evaluated by USSQ and IPSS at 4th day post-insertion of ureteral stent, follow-up day before removing of stent and post-removal of stent. The USSQ urinary symptom scores at day 4 comparing to day of removal of stent showed significant difference in between study groups (32 ± 6-13 ± 6 vs. 31 ± 6-14 ± 4 in Mirabegron and solifenacin, respectively) and without significant difference in control group. The USSQ body pain score significantly decreased in both Mirabegron and solifenacin groups at day of stent removal comparing to day 4 post-insertion of DJ with insignificant decreasing in the control group. Quality of life scores showed significant improving in Mirabegron and solifenacin group, and there was no difference in control group at 4 and 14days after treatment. No severe complications were observed in either group. In our series, we indicate that Mirabegron and solifenacin can be used to improve symptoms caused by the insertion of DJ-stent without significant difference.
