Efficacy of Liposomal Bupivacaine for Pain Control After Percutaneous Nephrostolithotomy

Summary

Percutaneous nephrostolithotomy (PCNL) is a common endoscopic procedure performed for upper urinary tract calculus disease. Despite being minimally invasive, it is associated with significant postoperative pain, often necessitating inpatient hospitalization and narcotic pain medications. Additionally, one of a number of catheters is often left protruding from the access tract for a period of time following the procedure, adding to patient discomfort. Attempts have been made to study peri-tubular or access tract analgesic installation, which have shown promise.1-2 However, no studies, to our knowledge, have examined the use of liposomal bupivacaine preparations in this regard. In this study we hope to prospectively analyze the use of liposomal bupivacaine injected to the access tract site at the time of PCNL and determine its effects on postoperative narcotic requirement and pain scores. Patients presenting for PCNL will be randomized to either the liposomal bupivacaine or usual care, which involves no injection of local anesthesia. Patients will then be followed during their inpatient stay. Total narcotic requirement (in milligrams) and pain scores (using Wong-Baker FACES rating scale) will be compared.3 Typical postoperative care and discharge criteria will not change during the course of this study.
