Randomized Controlled TrialIntermittent perirenal instillation of bupivacaine after tubeless percutaneous nephrolithotomy under spinal anesthesia: a double-blind, placebo-controlled clinical trial.
Pain at the surgery site is a common complaint in patients who experience percutaneous nephrolithotomy (PCNL). The aim of this double-blind, randomized clinical trial is evaluation of the effect of scheduled infusion of bupivacaine on postsurgical pain and narcotic consumption after tubeless PCNL under spinal anesthesia. ⋯ Intermittent perirenal instillation of bupivacaine via the nephrostomy tract after PCNL decreases the need for more systemic narcotics and provides acceptable analgesia in the postoperative period.
