Ultrasound-guided Transmuscular Quadratus Lumborum Block for Percutaneous Nephrolithotomy

Summary

Patients undergoing percutaneous nephrolithotomy (PNL) suffer from acute postoperative pain, despite a multimodal analgesic regime. We hypothesize that active (ropivacaine) transmuscular quadratus lumborum (TQL) block will significantly reduce postoperative opioid consumption and pain following PNL operation compared with placebo (saline) TQL block. The aim of this study is to investigate the effect of ultrasound-guided (USG) TQL block concurrent with a multimodal analgesic regime compared to the multimodal analgesic regime alone (and placebo TQL block) in a randomized and placebo controlled design.
