MIRABEGRON AND UAS OUTCOMES DURING RIRS

May 12, 2026 updated by: Arif Bedirhan Bayraktar, Ankara Training and Research Hospital

THE EFFECT OF PREOPERATIVE MIRABEGRON ON URETERAL ACCESS SHEATH INSERTION SUCCESS AND URETERAL INJURY DURING RETROGRADE INTRARENAL SURGERY: A RETROSPECTIVE COMPARATIVE STUDY

The aim of this study is to evaluate whether there is a difference in the passage rate of the ureteral access sheath between patients who used mirabegron (a beta-3 receptor agonist) for overactive bladder and those who underwent retrograde intrarenal surgery for kidney stones, and those who did not use mirabegron. Considering that beta-3 receptors in the smooth muscle of the ureter cause relaxation in the ureter, the hypothesis that the passage rate of the access sheath increases in those using mirabegron, thus facilitating access to kidney stones and improving surgical success, will be investigated.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Mirabegron Group
Patients using mirabegron for overactive bladder and scheduled for retrograde intrarenal surgery due to kidney stones.
Procedure: Retrograde intrarenal surgery
In our study, we evaluated the üreteral access sheath insertion rate in patients already using mirabegron for overactive bladder and scheduled for RIRS surgery for kidney stones. No additional intervention was performed beyond the routine surgical procedure.
Control Group
Not using mirabegron and scheduled retrograde intrarenal surgery due to kidney stones.
Procedure: Retrograde intrarenal surgery
In our study, we evaluated the üreteral access sheath insertion rate in patients already using mirabegron for overactive bladder and scheduled for RIRS surgery for kidney stones. No additional intervention was performed beyond the routine surgical procedure.
