Participants in this arm will receive an ultrasound-guided Quadro-Iliac Plane Block. The block will be performed at the end of surgery, before extubation, with the patient in the prone position under standard sterilization conditions. A convex ultrasound probe will be placed at the level where the quadratus lumborum muscle (QLM) attaches to the iliac crest to visualize the erector spinae muscle (ESM) and the underlying QLM.~The block location will be confirmed by injecting 2 mL of isotonic solution at the QLM-iliac crest junction. Subsequently, 20 mL of 0.25% bupivacaine will be injected, and the spread of the local anesthetic between the ESM and QLM will be observed under ultrasound guidance. The block will be performed bilaterally with a total volume of 40 mL.
