This is a randomized, triple-masked, placebo-controlled parallel-arm human subjects clinical trial investigating the addition of a continuous erector spinae plane nerve block to a single-injection erector spinae plane block to provide postoperative analgesia following percutaneous nephrolithotomy. Participants will all receive a single-injection nerve block and perineural catheter insertion. Following surgery, participants will be randomly allocated to receive either perineural local anesthetic or normal saline until the second day following surgery.
