Intermittent peri-tubal instillation of dexamethasone and ropivacaine on postoperative analgesia after percutaneous nephrolithotomy: A prospective randomized controlled trial.
Abstract
Percutaneous nephrolithotomy and placement of nephrostomy tube are performed for renal stones >2 cm in diameter. Attempts have been made to infiltrate local anesthetics with or without adjuvants into the surgical site to reduce pain. We hypothesized that there would be a significant prolongation of the analgesic effect of local anesthetic instillation along the nephrostomy tube due to the adjuvant dexamethasone.
