U.S., May 6 -- ClinicalTrials.gov registry received information related to the study (NCT07566416) titled 'The Effect of Preoperative Mirabegron Use on Ureteral Access Sheath Insertion' on April 28.
Brief Summary: 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 acces...
