The study will investigate the effects of ultrasound-guided ESPB and RLB on intraoperative and postoperative analgesia in patients undergoing PCNL to identify a safe and effective regional block method for postoperative analgesia
All the patients will be blinded to the intervention received in this study. All patients will receive standard general anesthesia technique with endotracheal intubation and muscle paralysis. Postoperatively, all patients will receive analgesia in the form of non-steroidal anti-inflammatory drugs and paracetamol. In case the VAS scores exceeded 4 in any group, the patients will receive rescue analgesia with 25 mg IV meperidine. In both groups, the ESPB and RLB will be performed after induction of general anesthesia using portable ultrasound device.
