Postoperative infection rates in low risk patients undergoing percutaneous nephrolithotomy with and without antibiotic prophylaxis: A matched case control study

摘要

Purpose: Current guidelines recommend prophylactic antibiotic therapy for all patients undergoing percutaneous nephrolithotomy. We examined the effects of antibiotic prophylaxis in patients undergoing percutaneous nephrolithotomy with negative preoperative urine cultures. Materials and Methods: Of the 5,803 patients in the CROES (Clinical Research Office of the Endourological Society) Percutaneous Nephrolithotomy Global Study database, a group of 162 patients undergoing percutaneous nephrolithotomy with a negative baseline urine culture who did not receive antibiotic prophylaxis were matched on preoperative nephrostomy, the presence of staghorn calculi and diabetes status with an equal number of patients who received antibiotic prophylaxis. Comparisons were made between the 2 groups in terms of operative and postoperative outcomes, including the incidence of fever and other complications.
