Introduction: To determine the clinical yield of stone culture in patients undergoing percutaneous nephrolithotomy (PCNL), and to identify patients who may benefit from this test.

Materials And Methods: We queried our database for all patients who underwent PCNL from 2005 to 2017, from whom urine culture (UC) and stone culture (SC) were obtained. Study endpoint was systemic inflammatory response syndrome (SIRS) within 48 hours of PCNL.
