Abstract

Before the advent of ultrasound guided regional anaesthesia, post-operative pain in percutaneous nephrolithotomy was mainly confined to opioid consumption and other analgesics. The use of Ultrasound in regional anaesthesia has facilitated the visualization of anatomical structures, needle advancement and the spread of local anaesthetic. This has led to the development and refinement of fascial plane blocks. Quadratus Lumborum block (QLB) facilitates early postoperative ambulation and reduction in length of hospital stay by effective postoperative analgesia.
