NCT04800302

Brief Summary

Percutaneous nephrolithotomy (PCNL) is considered to be the first choice and a more conservative procedure than open stone surgery. Not only postoperative pain related to dilatation of the renal capsule and parenchymal tract, but also patient's discomfort \& nephrostomy tube-related stress are reported to delay recovery time and increase the complication rates. This study is designed to provide postoperative analgesia by using ultrasound-guided continuous Quadratus Lumborum Block (QLB) III in patients undergoing PCNL and to assess pain scores \& side effects with less opioids consumption.

Procedure: Intra-venous Morphine

Interventions

Continuous infusion of Bupivacaine 0.125 % at a rate of 0.1 ml/kg/hr (not exceeding 12 ml/hour), infused through a catheter inserted in the plane between quadratus lumborum \& psoas major muscles with ultrasound guidance.

Continuous QLB group

Single injection of a mixture solution of 20 ml Bupivacaine 0.5% + 10 ml Lidocaine 2%, injected through a needle inserted at the posterior aspect of the quadratus lumborum muscle between it and erector spinae muscle with ultrasound guidance.

Continuous QLB groupSingle dose QLB group

Intra-venous Morphine \[0.1 mg/kg\] as rescue analgesic shots when the Visual Analogue Score (VAS) for pain exceeds 4.
