A multimodal analgesia regimen is suggested after nephrectomy, although some patients still report agonising pain. Regional anesthesia approaches may improve postoperative pain management and reduce the requirement for opioids after renal surgery.QLB provides early and rapid pain relief

The patient will be placed in the lateral position, after sterilization.. QLB will be done using ultrasound, The probe will be positioned superior to the iliac crest, in the transverse orientation, at the posterior axillary line. The Shamrock sign will be identified at the L4 level, and the insulated nerve block needle will be advanced from posterior to anterior, through the QL muscle, until the needle tip is visualized in the interfascial plane between the QL muscle and psoas muscle. As the correct needle placement is confirmed with 2-3 mL of saline, 20 mL of 0.25% bupivacaine will be injected ensuring that the psoas muscle will be pushed deeply.
