ESP Block vs Control for Pain Control Following Percutaneous Nephrolithotomy

Description

The purpose of this study is to investigate the use of the erector spinae (ESP) block in reducing the morphine milligram equivalent (MME) consumption post percutaneous nephrolithotomy. Objectives: 1. - Determine if there is a significant effect on post percutaneous nephrolithotomy MME consumption with the usage of an ESP block vs. saline control. 2. - Determine if there is a significant effect on reported pain levels with the use of an ESP block vs. saline control in post percutaneous nephrolithotomies.
