Background: Percutaneous nephrolithotomy (PCNL) a minimally invasive method for the removal of renal calculi and is associated with significant pain in postoperative period. Conventionally, intravenous opioids, local anesthetic infiltration, and regional blocks (intercostal/paravertebral blocks) have been tried with less efficacy to control postoperative pain. The present study is conducted to assess the effectiveness of erector spinae plane block (ESPB) performed under fluoroscopy guidance for postoperative analgesia during PCNL. Subjects and Methods: After obtaining ethical clearance, the study was conducted on 61 American Society of Anaesthesiologists (ASA) I and II patients aged between 18–65 years admitted for PCNL. Group I (n = 30) did not receive ESPB while Group II (n = 31) received ESPB under fluoroscopy guidance and 20 ml of 0.375% ropivacaine was administered after PCNL. Patient-reported pain intensity using visual analogue scale (VAS) was considered as a primary outcome. The hemodynamic variables (heart rate, systolic, diastolic, and mean blood pressure) was considered as a secondary outcome. Statistical analysis was performed using Student's t-test and Mann–Whitney U test. Data analysis was performed using the Statistical Package for the Social Sciences version 23.0. Results: Postoperatively VAS score was significantly lower in Group II at 0, 1, 2, 3, 4, 6, 12, 18, and 24 hours after PCNL (P < 0.001). Dose of rescue analgesia significantly decreased in Group II compared to Group I. Conclusion: ESPB performed under fluoroscopic guidance is a simple and effective technique and it provides significantly better postoperative pain relief.
