Summary
Extracorporeal shockwave lithotripsy (ESWL) is widely used for the treatment of urinary tract
calculi; however, the vast majority of patients do not tolerate the procedure without
analgesia and sedation.
Lots of methods have been tried to control this pain (non-steroidal anti-inflammatory drugs,
opioids, alpha 2 agonists, transversus abdominis plane block with long-acting local
anesthetics, paravertebral block, local anesthetics infiltration, lidocaine/prilocaine
cream).
The quadratus lumborum block was first described by Blanco. QL block is performed as one of
the perioperative pain management procedures for abdominal surgery. QL block provides
anesthesia and analgesia on the anterior and lateral wall of the abdomen.
