What this trial studies

This clinical trial aims to evaluate the effectiveness of the erector spinae plane (ESP) block in providing postoperative pain relief for patients undergoing flexible ureterorenoscopy (URS) surgery. Participants will be randomly assigned to either receive the ESP block with bupivacaine or standard pain management without the block. The study will assess pain levels, opioid consumption, the need for additional pain treatment, and the incidence of postoperative nausea and vomiting (PONV) in the first 24 hours after surgery. The ESP block will be administered under ultrasound guidance to ensure accurate placement of the anesthetic.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 undergoing elective flexible ureterorenoscopy with an ASA classification of I-II.

Not a fit: Patients with a BMI over 35, allergies to local anesthetics, or those requiring emergency surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management and reduce opioid use after URS surgery.

How similar studies have performed: Other studies have shown promising results with the use of ESP blocks for postoperative analgesia, suggesting this approach may be effective.
