Summary

The aim of the study is to evaluate the effect of preoperative taking alpha-blockers (tamsulosin or silodosin) on the success rate of ureteral access sheath (UAS) insertion and the degree of ureteral injury during RIRS in non-prestented patients.

The results showed that patients who received alpha-blockers had a higher rate of successful UAS insertion and a lower degree of ureteral injury compared to non-prestented patients. In addition, patients with a BMI greater than 25 kg/m² and those older than 59 years demonstrated a higher success rate of UAS insertion and lower degree of ureteral injury.
